each year (Turkington‚ Carol) According to James Cobb from the World Book Online Reference Center mine safety involves four main types of problems including accidents involving machinery‚ roof and rib failures‚ accumulations of gases and concentrations of coal dust. The accidents involving machinery kill and/or hurt more coal miners in a year than any other mining accident. The machinery in mines are located in cramped spaces with little light‚ causing miners to have two times the chance of accidents

The environmental impact of mining includes erosion‚ formation of sinkholes‚ loss of biodiversity‚ and contamination of soil‚ groundwater and surface water by chemicals from mining processes. In some cases‚ additional forest logging is done in the vicinity of mines to increase the available room for the storage of the created debris and soil. Besides creating environmental damage‚ the contamination resulting from leakage of chemicals also affect the health of the local population.[2] Mining companies in some

A land mine is an explosive device‚ concealed under or on the ground and designed to destroy or disable enemy targets as they pass over or near the device. Such devices are typically detonated automatically by way of pressure from the target stepping or driving on it‚ though other detonation mechanisms may be possible.[1] The device may cause damage either by a direct blast or by fragments that are thrown by the blast. The name originates from the ancient practice of military mining‚ where tunnels

Botswana and Malawi. Not one of them would see home again. They were imprisoned and would be chained to their work stations with shackles and would go for months at a time working in near total darkness down in the mines. Soon the mines started to flood. The water was trapped in the mine with nowhere to go; they never set up a drainage system. With the gold miners shackled to their work stations they were now forced to work in disease infested water. The water came all the way up to their knees and
