摘　　要：针对某矿2_(-2)煤层和3煤层具体地质条件,首先通过理论计算对2_(-2)煤层上行开采可行性进行研究,判定2_(-2)煤层在采取一定措施后可以进行上行开采。利用UDEC对3煤层开采后,2_(-2)煤层及其顶、底板所受采动影响进行模拟,验证了理论分析的正确性。According to the specific geological condition of 2-2 coal seam and 3 coal seam in a mine, first of all, the feasibility of upward mining of 2-2 coal seam is studied by theoretical calculation. It is concluded that 2-2 coal seam can be mined upward after taking certain measures, the mining effects of 2-2 coal seam and its top and bottom are simulated by UDEC after 3 seam mining. The correctness of the theoretical analysis is verified.
