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
Underground mining is used for small, high-grade deposits covered with a thick soil or rock above the ore. surface mining is commonly used to extract coal and copper. Underground mining is used for zinc, lead, and increasingly coal. Alluvial mining is used for precious metals like gold and diamond.
Whether the mining is being done at the surface or underground will determine the kind of equipment used. Heavy mining equipment used for surface mining may be used in the furtherance of any number of mining processes. For instance, it may be used during oil mining, coal mining or the mining of precious stones and metals.

Water. Large quantities of water are used in mining operations for cooling machinery, dust suppression, cleaning, fire-fighting and drinking. Water supplies are normally carried in steel pipes from surface to points close to the work places, with flexible hoses used for the final connections. One of the primary uses of water underground is for ...
Crushing equipment is particularly useful for strip mining, which uses open-pit mining to locate and extract coal or ore. In these mining operations, conveyors bring the materials to the mining trucks for transport. Crushing equipment lowers the use of excavated resources while eliminating the material amount at the site. Earthmovers

The underground method of coal mining currently utilizes two main techniques room and pillar mining, and longwall mining 1. Room and pillar mining involves cutting a system of rooms within the coal seem. Pillars are left in order to support the roof of the cut into coal seem.
Cat Plow Systems for Low Seam Coal. Plowing is the preferred longwall mining technique for seams below 1.8 m (71 in), and under specific geological conditions, even below 2.3 m (90 in). Today, Caterpillar is the market leader in the field of fully integrated and automated plow systems.
There are two types of room and pillar miningconventional mining and continuous mining. Conventional mining is the oldest method and accounts for only about 12% of underground coal output. In conventional mining , the coal seam is cut, drilled, blasted and then loaded into cars .
