At the time, coal mining operations remained small businesses. A skilled miner could employ a few laborers to extract coal close to the surface. Many coal seams were exposed on hillsides or river banks, and those rivers allowed coal barges easy access to the mines. Labor relations and coal mining did not become contentious until much later.

The original mission of the USBM was to provide the mining industry with information on blasting materials and techniques that could be used safely in the presence of flammable mine gases and dust. This meant identifying the chemical and physical characteristics that allowed explosives to perform usefully without initiating disastrous fires and explosions. These considerations defined the two main objectives of the USBMs initial research and development - safer blasting materials for underground coal mines, and prevention of underground mine gas and dust explosions.

Although administratively headquartered in Washington, DC, the principal research activities were conducted by the Pittsburgh Mining Experiment Station under Dr. Holmes. According to the Organic Act, the USBM was, among other things, to make diligent investigation of the methods of mining, especially in relation to the safety of miners, the use of explosives, the prevention of accidents. This reflects the origin of what eventually became known as the Pittsburgh Research Center.

In establishing the USBM, Congress undoubtedly was mindful of similar test stations established earlier in England, Germany, Belgium, Austria, and France, whose work had done much to reduce the frequency and severity of coal mine accidents. Recogniing this, the Secretary of the Interior had requested a delegation of foreign experts to visit U.S. mines to make recommendations to improve safety and efficiency. Thus, the groundwork for the birth of the USBM had been laid.

At the Experimental Mine, work focused on identifying the processes associated with initiation, growth, and eventual extinguishment of mine fires and explosions. There, under conditions similar to those of a working mine, it was learned how weak methane explosions can initiate violent coal dust explosions and how rock dust, water, and other quenching agents can be applied to arrest these explosions. Instruments were developed for the early detection of open flames and incipient fires due to spontaneous combustion.

In mountainous areas, strip mining may be the first stage of a mines life. Coal is dug from the surface, resulting in ribbons of stripped land stretching around a mountain, and sometimes forming large pits. Strip mining is relatively low cost, requiring perhaps only a backhoe and a dump truck. Profits from strip mining are sometimes used to purchase equipment needed for interior mines.

Unless subject to enforced regulation by government, strip miners tend not to remediate the stripped land afterwards, resulting in long term soil erosion and landscape defacement. Remediation of a strip mine could involve removal of waste materials, restoring the original slope of the land, securing the restored contour from erosion, and replanting or reseeding of vegetation.

Drift mines may be dug horiontally into a mountain after strip mining has used up surface coal. Drift mines may be shallow, and when they are, miners may be unable to stand up and must instead lie flat on flattened vehicles moving inside the tunnel. Drift mines with a height of about 28 are typical in southwest corner of Virginia.

Early mining methods led to very unsafe mines which were never adequately represented on maps, or were mapped inaccurately.1 Older mines often had irregularly spaced supporting pillars, making the tunnels more likely to cave in. Modern mines have regular pillars at safe intervals of known thickness, correctly represented on a map. Nevertheless, there is always a risk of cave-ins when mining underground.

Then, while the 78 miners still lay entombed in the burning mine, W.A. Tony Boyle, the UMWAs ruthless president, praised the coal companys horrendous safety record even though federal and state safety inspectors had cited it for multiple safety violations that year. When consumer champion Ralph Nader subsequently exposed the fact that Boyle, his family and his cronies were using the unions treasury as their personal piggy bank, it finally pushed Joseph Jock Yablonski, a former miner and long-time union insider, over the edge.
