Coal mines in Illinois and Kentucky tend to have relatively low inflows of ground water. Many of these mines are characterized by soft shale roof rocks rather than sandstone. The majority of mines in Illinois report pumpages of less than 100 mVd (26,400 gpd) (Cartwright and Hunt, 1978). Where water does enter mines, the mines are generally ...

Underground mining operations around the world pose similar risks to worker safety and health. Though different techniques are used to extract base metals, precious metals, nonmetallic minerals, diamonds and coal, the hazards do not differ that much. The deeper the mine, however, the greater the risk. Safety Challenges in Underground Mines

Most coal mines are large undxgrouncf complexes, many of which are 50 km2 or more in area and have up to 16 working sections operating simultaneously. Production from such a mine may be 3-million tons per year; in the U.S., the vast ma- jority of underground coal is mined primarily with continuous mining machines and shuttle cars. B.

Through-the-Earth (TTE) signalling is a type of radio signalling used in mines and caves that uses low-frequency waves to penetrate dirt and rock, which are opaque to higher-frequency conventional radio signals.. In mining, these lower-frequency signals can be relayed underground through various antennas, repeater or mesh configurations, but communication is restricted to line of sight to ...
