摘要
瓦斯灾害事故是煤矿重要安全问题。为有效预防瓦斯超限引发的各类瓦斯灾害事故,通过进行相似性模型矿压试验模拟煤层顶板冒落规律,利用关键层理论,结合模型试验结果,总结采空区顶板冒落规律,进行工作面高位钻孔抽采参数优化设计。
Gas disaster accident was important to mine safety. In order to prevent disasters and accidents caused by transfinite gas, through similarity model pressure test simulation of coal seam roof caving rule, using the key strata theory, combined with model test results, goal roof caving rule was summarized to conduct face high drilling extraction parameters optimization design.
