Waste filling technology under condition of complicated geological condition working face

With the deep development of mining in China, the problems, such as complicated mining conditions, bad coal result of dirt band and fault, and environmental pollution caused by waste, are more and more serious. In order to dispose waste in underground and ultimately improve the quality of coal, the secerning mining and transporting and waste filling technology and filling equipments were studied, the faultage that was less than mining height and the dirt band that was bigger than 150mm, were secerning mined and transported, and the detached dirt band was filled in the face end triangle by filling equipments. It carries out that the quality of coal is ultimately improved, the assistant exaltation is liberated, and the environmental threat caused by waste is eliminated.
