| Abstract: | At present, the subsurface coal cutting methods at home and abroad have mainly divided into three types: shortwall type coal cutting method, progressive type coal cutting method, and retreat type coal cutting method. The working principle of Z type coal cutting method and its applied result in No.3 mining area of Bishan, Ruzhou City have been all sidedly contrasted and analyzed in this paper. This coal cutting method has all the important significance to bring about the unity of 4 type's benefits and healthy development, to prolong the service life of a pit and to turn the superiority of resources into superiority of economy. |
