The invention belongs to the technical field of application of
coal mining equipment and
coal mining method, and for solving the problems that conventional 'three unders (under building, railways and water bodies)' unexploited
coal filling is high in cost and low in efficiency, matched
filling materials are mostly
solid filling materials, the transport project amount is large, the filling speed is slow, transportation and filling are difficult to match and synchronize, and the goaf compacting effect is not ideal after filling, provides a continuous
coal mining machine paste filling mining method; a main lane and an auxiliary lane are arranged at the middle part of a mining area, the two lanes are connected through connection lanes at intervals, two sides of the main lane and the auxiliary lane are each provided with remining branched lanes, and two sides of each branched lane are each provided with mining adits for re-mining. A continuous
coal mining machine performs re-mining at the one-side branched lanes, and a paste filling
system performs goaf
filling in the-other-side branched lanes. The mining and filling parallel operation is achieved, damage of
coal mining on ground buildings (structures) and ecological environments is reduced, the
economic benefits of the 'three unders' coal mining is increased, the mining and filling efficiency is high, equipment movement is flexible, the process is advanced, and the method is the quite ideal 'three unders' unexploited coal mining method.
