非导水陷落柱采动裂隙发育深度研究

Research on Development Depth of Mining Fracture in Non-flowing Water Collapse Column

  • 摘要: 为了探索采动对构造内岩体的影响,以晋煤集团成庄煤矿为试验现场,通过对比正常煤层与含非导水陷落柱煤层的底板采动破坏情况,综合研究构造的采动裂隙发育规律。结果表明:正常煤层与含构造煤层底板采动破坏深度的理论、模拟与工程探测结果均在19 m和31 m附近,结果吻合且可靠,即非导水陷落柱的采动裂隙发育深度约为正常煤层的1.7倍。
    Abstract: In order to explore the influence of coal mining on rock mass within the structure, taking Chengzhuang Coal Mine of Jincheng Anthracite Mining Group as testing site, through the contrast analysis of floor destruction in normal coal seam and non-flowing water collapse column, we comprehensively research the laws of mining fractures within structure. The results show that the results of floor mining-induced damage depth for normal coal seam and tectonic coal seam from numerical simulation, theoretical calculation and engineering tests are 19 m and 31 m; the data matched each other very well. In other word, the mining-induced fracture depth of non-flowing water collapse column is 1.7 times of the normal coal seam.
