SKJ Shearer is one of the main equipment of complete mining equipment. It is a large and complex system integrating mechanical, electrical and hydraulic pressure. Shearer is one of the important equipment to realize mechanization and modernization of coal mine production.
Coal mining - Coal mining - Underground mining In underground coal mining, the working environment is completely enclosed by the geologic medium, which consists of the coal seam and the overlying and underlying strata. Access to the coal seam is gained by suitable openings from the surface, and a network of roadways driven in the seam then facilitates the installation of service facilities.
Figure No. Description longwall face equipment is shown in Fig. 1.3. The shearer cuts a slice of coal from the coalface on each pass and a face conveyor, running along the full length of the coalface, carries this away to discharge of mining Goaf Longwall shearer conveyor Hydraulic roof supports.

Apr 08, 2012 This video by mining equipment manufacturer Job Global, educational than promotional, gives an excellent overview of longwall, versus room and pillar underground coal mining.
In traditional longwall mining, the shearer travels along the face of the coal seam, cutting as it goes and dropping coal onto an ar d face conveyor (AFC) that carries it to a belt or crusher. When a cut is complete, the whole system moves forward one step at a time until the seam is finished.

Mar 01, 2019 Both Caterpillar and Komatsu Mining make all face equipment and automation devices with Caterpillar in Germany and Komatsu Mining in UK except the shearer in the USA. Frequently they differ in design, but with similar functional purpose. So in this paper no attempt is to distinguish their products, only general description.
