摘要
针对王庄煤矿7106工作面综放开采导水裂隙带导通地表水体,引起矿井水害的问题,运用FLAC3D软件对7106工作面的各个开采阶段进行模拟,分析不同开采阶段下的塑性破坏区的变化规律,得到导水裂隙带发育最大高度135 m。通过对实测数据和数值模拟数据进行对比,验证了数值模拟的准确性,为7106工作面水下安全生产提供一定理论基础。
Aiming at the problem that the water flowing fractured zone of fully mechanized top coal caving mining in 7106 working face of Wangzhuang Coal Mine leads to surface water and causes mine water disaster,the FLAC3D software is used to simulate each mining stage of 7106 working face,and the change law of plastic failure zone in different mining stages is analyzed,and the maximum height of water flowing fractured zone is 135 m.By comparing the measured data with the numerical simulation data,the accuracy of the numerical simulation is verified,which provides a theoretical basis for the underwater safety production of 7106 working face.
