摘要
以五沟煤矿1011工作面煤层开采为例,应用FLAC软件对煤矿开采引起的煤层顶板覆岩运移规律进行了数值模拟,确定了含水层下煤层开采导水裂缝带和覆岩冒落带发育高度,利用经验公式和简易水文观测法对模拟计算结果进行验证,为进一步合理留设防水煤柱提供有效技术参数。
Taking 1101 Mining Face in Wugou Colliery as example, this paper applying FLAC to simulating rules of overlying strata movement induced by mining. Heights of water-conductive fissure zone and caving zone of overlying strata are obtained by numerical simulation and verified by empirical formula and simple hydrological observation, which provide effective technical parameters for reasonable water-proof pillar design.
