Section I of this article is commented by Pu Xianhong, Chief Engineer of Kuishan Mine, Zibo Mining Bureau. Sections II, III, IV and V were prepared by Comrade Pan Ruijin, a coal mine teaching and research unit of our institute. - Editor Ⅰ, Zibo Mining Bureau to study and adopt the objective requirements of the upward mining sequence Coal seam group mining is very important, should give the necessary attention. In general, the upper coal seam can be mined first, and then the lower coal seam can be successively mined. Under specific conditions, the lower coal seam can be mined first and then the upper coal seam can be sequentially mined. The top-down mining sequence is called the downstream mining sequence, and the bottom-up mining sequence is called ascending mining sequence. Both mining sequences will have an impact on the adjacent coal seams. According to the order of ascending mining, it sometimes causes serious subsidence, dislocation and integrity destruction of the above coal seam, causing difficulties in the mining of the above coal seam. However, with appropriate geological conditions and effective technical measures taken, the above coal seams and their surrounding rock can be balancedly sunk and their integrity can not be damaged. Therefore, there is no obstacle in mining the upper coal seam.
