根据矿区建筑物下煤层群实施条带上行开采的技术条件,应用理论分析、数值模拟等判定方法,对下层煤开采后,上层煤的连续性和完整性及保留煤柱的稳定性进行研究,确定条带上行开采方案的可行性。同时,验证不同判定方法联合应用的可行性。 According to the technical conditions of the upper mining of the coal seam group under the mining buildings, the continuity and integrity of the upper coal and the stability of the retained coal pillar are researched after the lower coal mining by applying the theory analysis and numerical simulation. Determine the feasibility of strip mining program. At the same time, verify the feasibility of joint application of different judgment methods.
