SMC's mining operations consist of two underground mines that have been developed on the 26mile strike length of the palladiumplatinum mineralized JM Reef. The two mines are the only major palladium platinum primary metal producing mines in North or South America. Both mines employ the same types of mining methods.
The Nabob Group is near Lawson, Colorado. Historically the site has been associated with the Dumont Mining District which is now part of the Arapaho National Forest. The Nabob Group is a underground mining operation. The ore mined is composed of chalcopyrite, galena and pyrargyrite with waste material consisting primarily of quartz.
Underground Mining. The length of the longwall block is about 3,000 meters to 5,000 meters. In a 3 meter thick coal seam the amount of coal in place in a block is six to seven million tons. The basic equipment is a shearer (a cutting machine) mounted on a steel conveyor that moves it along the face ( Figure 37 ).
Scrutiny of mine safety practices has increased in recent years due to highly publicized accidents, such as the Sago mine disaster of January 2, 2006, which resulted in 12 fatalities, and the Upper Big Branch mine disas ter of April 5, 2010, which resulted in 29 Subsequent investiga 1â he T term â mine disasterâ ...

Traction system. The 14BU27 includes our OptiDrive AC traction system, which is coupled to a compact, allgear transmission to provide smooth, reliable service.
Jan 25, 2019· Induced Seismicity: Mines located in seismically active regions, such as the Andean region — also known to be one of the wealthiest metallic mining zones in the world — are particularly at risk. Especially dangerous in underground mining areas, mineinduced seismicity also causes slope instability in surface mining.
Optimization principle of combined surface and underground mining and its applications. A new principle of the limit optimization is put forward through analyzing the limitations of moving cone method under such conditions. With a view to recovering as much mineral resource as possible and making the maximum profit from the whole deposit,...
