摘要
根据某煤矿的实际地质情况和开采工艺,从应力分析角度结合LMBP神经网络评价模型和数值模拟,对防水煤柱留设宽度进行分析,并将综合模拟结果应用于开采生产中。实践证明:防水煤柱合理的留设宽度为25m,比设计宽度缩小了20m,由此多回收大量的煤炭资源。
According to the actual geological conditions and mining process of a coal mine, the width of waterproof pillar was analyzed from the stress and combined with LMBP neural network evaluation model and numerical simulation. The simulation results were applied to the mining production. The practice has proved that the reasonable width of waterproof pillar of this coal mine is 25 meters,which is 20 meters narrower than the design pillar width. It will save large amount of coal resource.
