摘要
结合赵固二矿1105工作面厚煤层及承压水上开采的情况,运用数值模拟软件FLAC3D对煤层底板破坏规律进行研究,得出厚煤层承压水上开采底板垂直应力、位移和塑性区分布规律,避免了井下试验方法仅能确定底板特定部位的破坏情况。
Combining with the mining situation of Zhaogu coal mine 1105 working face thick coal seam above confined water,using the FLAC3 Dnumerical simulation soft studies coal floor damage rule,conclude the floor stress distribution displacement and plastic zone distribution rule of thick coal seam mining above confined water. To avoid the downhole testing method just determine the damage of the bottom parts.
