Modern Mining Underground
Modern mining increasingly uses automated techniques. We are using automated and continuous rock cutting vehicles to safely extract the targeted ore deep underground without the need for explosive blasting, thereby creating far greater rock stability and far less variance in the quality of the ore we extract.

Borer Miners For Continuous Smooth Operations
borer miners perform full-face cutting with two large radial cutters. They are designed to cut and deliver material to auxiliary haulage equipment in a continuous operation. borer miners can keep up with haulage equipment removing excavated material and offer an effective and highly productive solution for driving entries, mining rooms and extracting pillars.

What is Longwall Mining? (with pictures)
Longwall mining machines consist of multiple coal shearers mounted on a series of self-advancing hydraulic ceiling supports. The entire process is mechanized. Longwall mining machines are about 800 feet (240 meters) in width and 5 to 10 feet (1.5 to 3 meters) tall. The miners extract panels -- rectangular blocks of coal as wide as the mining

Underground soft
Underground soft-rock mining is a group of underground mining techniques used to extract coal, oil shale, potash, and other minerals or geological materials from sedimentary (soft) rocks. Because deposits in sedimentary rocks are commonly layered and relatively less hard, the mining methods used differ from those used to mine deposits in igneous or metamorphic

Cutting Machines
The plough height is the working height in the seam being mined (possibly a bit lower if the coal tops can be guaranteed to fall once the coal below is cut. These picks act in a fashion similar to chisels and break a narrow web of coal off the face (of the order of 300-400mm thick). In most cases there are no moving parts on a coal plough.
