Methane gas is found naturally in most coal seams. It includes many volatile organic compounds including methane, ethane, butane, propane, and contaminants. Methane is the most common ingredient (>50%) found in natural gas. It is the most common dangerous gas found in underground coal mines.
rock bursts in underground coal mines. Each mine operator is required by 30 CFR (a) (1) to develop and follow a roof control plan, approved by the Mine Safety and Health Administration (MSHA) District Manager, that is suitable to the prevailing geological conditions, and the mining system to be used at the mine.
An application involves the manual process of extracting and hauling coal where operators, in tight confines of a mine, can be struck or caught by mobile machinery. The approach to remedy this problem uses a guidance system on the continuous haulage equipment so that it follows the continuous mining machine that extracts coal.

Coal dust explosions in underground coal mines are prevented by generous application of rock dust (usually limestone). If an explosion should occur, the rock dust disperses, mixes with the coal dust and prevents flame propagation by acting as a thermal inhibitor or heat sink.
Aug 16, 2013· A coal dust explosion is one of the principal hazards in an underground coal mine. These mines must develop, establish and maintain an adequate and effective safety and health management system (SHMS) to ensure risk from such hazards is at an acceptable level. One of the primary controls against this hazard is the application of stone dust throughout mine roadways to reduce the potential .

Between 1880 and 1920, southern West ia''s population grew from 93,000 to 446,000, due almost entirely to the coal industry. The region''s first coal miners primarily were African Americans, both enslaved and free. By 1850, approximately half of Kanawha County''s slaves worked in the salt industry—many mined coal to fuel the furnaces.
Surface mining is generally considered to provide better recovery, grade control, flexibility, safety, and working environmen ts than underground mining. Figure 3 shows a comparison of the total injury rates in US coal mines. The injury rates have declined both in surface and underground mines. However, the total number of injuries per one million
