Now commonly used in fully mechanized long wall technology and traditional cannon, there exist many defects, mining technology and continuous mining machine room and pillar mining technology has its unique characteristics, can overcome the defects in the mining, it can improve the technical longwall fully mechanized mining, digging the connection relationship between and caused a series of problems, therefore, it is in the geologic conditions are complex coalfield, marginal coal and blended coal field, irregular coalfield, and widely used in place of coal mining, this article from the basic research, technology system, and the key equipment of short-wall mining method, systematically studied the continuous mining machine room and pillar short-wall mining technology.
