WASHINGTON, Oct. 28 /PRNewswire-FirstCall/ — Massey Energy (NYSE: MEE) today accepted three Sentinels of Safety Awards in Washington, DC. The annual Sentinels of Safety award program recognizes achievement of outstanding safety records in America's mineral extractive industries. The Sentinels of Safety awards program is co-sponsored by the National Mining Association (NMA) and the Mine Safety and Health Administration. Massey is the first mining company ever to receive three of the mining industry's most prestigious safety awards in one year.
(Logo: http://www.newscom.com/cgi-bin/prnh/20071031/MASSEYENERGYLOGO )
The three Massey facilities to receive the Sentinels of Safety awards include:
- Chess Processing, of Elk Run Coal Company, in the Large Coal Processing Facility Group
- Chesterfield Preparation Plant, of Omar Mining Company, in the Small Coal Processing Facility Group
- North Surface Mine, of Alex Energy, Inc., in the Small Surface Coal Group
“At Massey Energy, we embrace our commitment to safety at all levels — from executive to miner. The Sentinels of Safety awards reflect the Company's dedication to safety at all of our facilities,” said Massey Chairman and CEO Don L. Blankenship. “No coal company can succeed over the long term without a total commitment to safety. More importantly, Massey is a family. We care about protecting our fellow members, which is why we strive to remain an industry leader in safety,” added Mr. Blankenship.
2008 marked the safest year in Massey history, and fifth straight year in which Massey's safety performance was stronger than the industry average. In fact, Massey's safety performance has been stronger than the industry average for 16 of the past 18 years.
The Sentinels of Safety awards recognize facilities with the lowest “no days lost” injury incidence rate, with the tie breaker being the most employee hours worked. The bronze-colored trophy remains in the custody of the mining operation for approximately one year. The operation then receives a replica trophy and the bronze trophy is transferred to the following year's winning operation.
Massey Energy Company, headquartered in Richmond, Virginia, with operations in West Virginia, Kentucky and Virginia, is the largest coal producer in Central Appalachia and is included in the S&P 500 Index.

Introduction to the Gold Mining Process for Tabular Ore Bodies
There are a number of different methodologies used to conduct mining operations. One of these methods are discussed in this article.
The gold bearing ore is in situ in the reef band where it was deposited millions of years ago. It requiers drilled and blasted to free it from the country rock. According to Nell (1984:95) this process is called stoping. He defines stoping as:
the actual mining of ore by means of breaking ground in stopes to a size suitable for handling and processing for the recovery of the mineral content.
The breaking of the country rock includes drilling blast holes and blasting it. This is followed by cleaning, supporting and the providing of the infrastructure to the stope faces.
The provision of infrastructure includes the maintenance and managing of:
• in stope water and air services that is necessary for the drilling and dust allaying process
• travelling ways to and from the stope necessary for creating access ways for people and material
• scatter walls to contain the blast rock in a conveniently concentrated muck pile for the cleaning crew,
• material and people handling appliances including monorail, mono rope and chairlift devises
• double drum winches and scraper scoops for the moving of blasted rock
• pumping and pump installations to ensure sufficient water pressure and or clear out the accumulation of excess water from low lying areas.
• rail tracks for the locomotives and trains that transports workers, material and broken rock pover long horizontal distances underground.
• Safety devices that include tips and grizzlies to prevent inadvertent access of people down these near vertical excavations.
• Blasting equipment that includes remote blasting system cables and ventilation sensor equipment in the intake and return air passages.
• Ventilation systems that consists of various sizes of columns, temporary and permanent ventilation brattices, -walls, -holings and fans.
• Electricity and electric equipment required for the use during the mining process.
With reference to figure 1 a three dimensional mining layout of a typical gold mine can be viewed here. The figuredepicts the basic components, in three dimensions, used to explain the mining layout of a typical gold mine.
The broken ore is typically scraped on dip, down a 30 meter stope face into a strike gully, by means of a double drum winch and scraper scoop once it is blasted from the country rock.
Another double drum winch and scraper scoop is used to scrape the broken rock on strike to an orepass or boxhole, situated in the original raise. This boxhole can be situated up to 90 meters from the face where the blasting took place. The broken rock now cascades down this steeply inclined excavation (boxhole or orepass) to a crosscut on a lower level.
In the crosscut a train, normally with ten eight ton hoppers are used to transport the broken rock to the shaft. The shaft can be kilometres away from the point of mining. At the shaft the train tips it's cargo down the shaft orepass system, where it again cascades down to the shaft loading station near the bottom of the shaft. The broken rock are hoisted up a 2000 meter vertical shaft in rock skips with a typical capacity of 12 tons by means of a rock hoist to surface, in the case of a surface shaft, or to just above the loading station of the surface shaft in the case of a sub – shaft.
On surface the broken ore is transported to the metallurgy plant by means of a conveyor belt. In the metallurgy plant the ore is milled, screened, and chemically treated in order to allow separation of the gold from the gold bearing ore. The slime residue is pumped to a tailing dam and the gold concentrate is further treated. The gold concentrate is smelted and the 89% pure gold is poured into gold bars weighing about 31 kilograms each.
These gold bars are then transported to a Refinery where the silver is removed and the gold refined to 99.99% purity. It is this pure gold that is sold on the world gold markets.

It's tough to beat gold, isn't it? There's no better medal
to win in the Olympics. For many people, there's no better
component of jewelry. And when it comes to investing, quite a
few folks think that other investments just aren't as safe or
lucrative.
Well, that's just wrong. You might think of gold as
safe-ish because it's a tangible item that exists in limited
quantities, and because piles of gold bars in a vault
somewhere won't be worth nothing anytime soon. Think
again.
Stocks are tied to tangible things, too: actual
bricks-and-mortar companies.
Merck (NYSE: MRK) stock is tied to Merck
buildings and Merck employees and lots of research and
formulations of medications and patents.
Chevron (NYSE: CVX) stock is tied to
oil-related equipment and data, to oil fields, pumps, and
refineries, and to more buildings and employees, among other
things. It's not likely that those kinds of assets will
suddenly become worthless, or that the demand for energy and
medications will shrivel up.
Great companiestend to hold their value.
Gold's mixed results
Those who think gold is a great investment need to
think again, too. Sure, it
canbe one. And it
hasbeen one — now and then. But over long periods,
it doesn't have the best track record. Check out what $1
invested in various things between 1802 and 2006 would have
grown to:
Investment
Real Return, in 204 Years
Dollar
$0.06
Gold
$1.95
T-bills
$301
Bonds
$1,083
Stocks
$755,163
Data: Jeremy Siegel,
Stocks for the Long Run.
As you can tell from the dollar's return, those numbers
are inflation-adjusted. A mere $100 investment would have
netted you more than $75 million in stocks, while your money
wouldn't even have doubled in value if you owned gold.
I know, none of us will be investing for 204 years. And
gold has done well lately; it recently topped $1,000 per
ounce. That's more than twice where it was five years ago.
But check out these returns:
Between
Total Gain or Loss
1900 and 2000
1,372%
1900 and 1950
83%
1970 and 1980
1,607%
1980 and 1990
(38%)
1990 and 2000
(27%)
Data: National Mining
Association.
Clearly, you can do rather poorly with gold over various
long periods. The 1970-to-1980 period is legitimately
exciting, with an annualized 33% gain. But even the overall
1,372% gain isn't so hot, since it's over 100 years.
Annualized, that comes out to just 2.7%.
You can do better
So go ahead and invest some of your money in gold if
you really believe in it. Just know that with prices near
all-time highs, it might be more likely to fall in value than
to keep rising — which is why it's good to seek out
investments that seem cheap. But consider parking much of
your money in places where it's most likely to grow well for
you, such as stocks.
You could follow the advice of Warren Buffett and us at
The Motley Fool and just opt for one or more simple index
funds, which will track the overall stock markets for you.
The
Vanguard S&P 500 (VFINX) fund, for
example, tracks 500 of America's biggest companies, including
Hewlett-Packard (NYSE: HPQ),
Disney (NYSE: DIS), and
DuPont (NYSE: DD).
If you want to aim even higher than that, you might add a
handful of carefully selected stocks to your mix. One way to
find some is to screen for them. Here, for example, are some
potentially undervalued companies I found when I screened for
market caps of $2 billion or more, price-to-earnings (P/E)
ratios of 20 or less, three-year revenue growth rates of 10%
or more, and four or five stars (out of five) in our
CAPS
community of investors:

Rolling east. Noon. The sun beat down hard on the black top road. Reflecting water that was not really there, glimmering on the asphalt ahead. The heat shimmered up from the ground, slamming into me with every passing mile. Sixty, seventy miles an hour, the only thing I hear is the firing of the engine and the hiss of hot air passing around the helmet straps. The motor sucks up what it wants from the atmosphere, mixes it with fuel, uses it then spits out what remains at the end of the shiny metal pipes behind me. The hypnotic rumble of the big Hog is my only companion.
Alone, the way I like it. I will never be any good at crowds. The landscape flattened after I put the little towns in my mirrors. The middle of Florida is the part the Mouse won't let you see. Trees and swampy enclaves give way to prairies into which man has dug great big holes. Little two lane roads intrude upon these scenes in the scarred flatlands made artificially hilly by the giant stacks of gypsum dotting the plains like crumbling, burned out volcanoes. The holes are the result of a hundred years of phosphate mining and before phosphate, dolomite. Fertilizers for nearly every crop on the planet.
I had not seen a soul in miles. Passed two decrepit gas stations, one offered Pepsi on a faded red, white and rusty blue metal sign. The placard leaned on its side. The letters still visible above the panic grass spelled Pep. A dust devil blew debris across the otherwise colorless parking lot.
The smell was acrid as the fetid winds blew all kinds of chemicals off the surfaces of the upturned dirt. Liquid, pooled in the center of the stacks is a mixture of sulfuric acid and rainwater runoff. The process of making fertilizer is a breakdown of what is beneath the ground combined with caustic additives. The whitish, dusty residue of these efforts coats everything. I tasted the smell with every breath. I throttled down to bump over grassy railroad tracks. A pair of dark winged buzzards eyed me nervously. They stood guard over some disgusting roadside delicacy, intermittently pecking and looking me over as I passed.
A giant drag line came into view as I rounded the next turn. A machine as big as a house, it was digging enormous amounts of dinosaur remains and dumping the piles into trucks that looked too big to move. The claw arm of the crane looked like some kind of prehistoric creature itself, its long neck extending in some subterranean hunting effort. The machine looked unmanned, and could have been, except for the relentless movement of its singular task. Grit from a hundred million years of decay found its way into the creases in my face, burning my eyes, powdering me through my jeans.
The intense heat conspired with the other desert conditions to underscore the bleakness of the bombed out terrain. Small insects, love-bugs mostly, began blowing in black and orange sheets across the road. Unable to fly against the wind, the bugs were driven to mate and die at the whims of the breezes. Love-bugs have a short life, mating in flight and mostly dying on the windshields of tourists as they cross Florida. The bugs started exploding against me. Two at a time, their tiny bodies shattered as they hit my face. Each time one hit unprotected skin, there would be a sting and then I could feel a spot of coolness as they vaporized. The remains threatened to block my vision as my glasses got covered in little black wings and entrails.
Just then I saw three other bikes. They were pushing hard coming from the opposite direction. The three were major American made, custom rigs. All three riders were dressed in official Harley gear from head to toe. One of the guy's helmet was painted the same teal color as his tanks and fenders. I knew they were riding in the same bug storm that I was experiencing. These were the quintessential Rolex riders that are the subject of much derision within the true biker community, but here they were, ten miles back of sunset. This was no parade. There was no audience. No one to see any our shiny machines.
Cruising on their decked out rub (rich urban biker) machines, with grim smiles, jaws clenched, they nodded and waved as we passed. These guys were solidly in their fifties, had probably made a bunch of money in the stock market or maybe they were lawyers, or work in banks. Looked down upon by those men and women who ride Billy-bike-wannabees mainly because they haven't saved up enough money for anything more reliable than an old shovel-head Harley with a gazillion miles on it since the last top end job. I guess to some, I fit that category too. I figured that two wheels is two wheels no matter what. I started hoping for rain as my arms turned redder by the minute from the blazing sun.
I had to stop for a minute to clear off my glasses. I pulled over on the edge of a chemical company plant access road. I saw the processing plant off in the distance. The building was mostly girders and tanks. Grey or faded black in color, coated with a fine layer of dust and corrosive chemicals. Smoke and steam rose from the industrial complex. All the factory lights were on and twinkled brightly in the midday sun, little dots of yet more heat and light.
I cranked it back up and thoughts turned to my own father. Today would have been his 96th birthday. As a cop on a Harley, he had ridden roads like this on two wheels back in the nineteen twenties. He told me once that he had ridden Indians but always went back to Harleys. It was one of those things that did not mean much at the time, but it came back right then. I figured that I was not fifty miles from where he rode once, from where he rests today. I heel shifted up the gears into fifth, pretending for a moment, to work the mechanisms like they probably did “back then”. Bugs continued to splash off my glasses. I smiled as I twisted back the throttle.
