平煤三矿十采区瓦斯涌出量预测 摘 要: 通过对平煤三矿的实际考察,收集了该矿大量的瓦斯资料和地质资料，经过整理分析得到各种地质条件、各种开采条件下的实际瓦斯涌出量。同时结合已学的瓦斯基本理论，根据瓦斯原始含量、矿井开拓方式、煤层赋存及煤质、煤层瓦斯含量分布规律等条件，运用分源法对该矿十采区瓦斯涌出量进行预测；通过对本采区的瓦斯涌出量预测对该采区的通风设计,瓦斯抽放设计与瓦斯管理提供技术支持，对该矿瓦斯防治工作具有一定的指导意义。 关键词: 瓦斯含量 平煤三矿 分源预测法 瓦斯涌出量 THE NO.3 MINE OF PINGMEI GROUP THE NO.10 PICK AREA GAS TO WELL UP Abstract: Through to the even coal three ores actual inspections, has collected this ore massive gas material and the geological data, obtains under each geological condition, each kind of mining condition actual gas after the reorganization analysis wells up the out put. Simultaneously unifies already study the gas elementary theory, according to the gas primitive content, the mine pit development way, the coal bed tax saves and the anthrax, condition and so on coal bed gas content distribution rule, the utilization device source law ten picks the area gas to this ore to well up the output to carry on the forecast; Through to this picks the area the gas to well up the output to forecast to should pick the area to ventilate the design, the gas pulls out puts the design and the gas management provides the technical support, has the certain instruction significance to this ore gas preventing and controlling work.
