Study on Feasibility of near Distance Coal Seam Group Ascending Mining

Abstract:

This paper, from the advantages and disadvantages of the conventional judgment methods of ascending mining feasibility, put forward the judgment criterions of near distance coal seam group ascending mining feasibility. And it is used the method of numerical simulation for the correlation analysis and verification. According to the existing ascending mining feasibility the judgment method has certain limitation. Therefore put forward the new determination method. Engineering application has some significance.
