摘要
根据成庄煤矿的地质条件构建了数值模型,通过数值模拟得出了不同条件下的钻孔周围瓦斯压力分布状况;根据临界压力,得出了瓦斯抽放有效半径;并对该矿的瓦斯抽放数据进行分析。
In the text, numerical simulation model was constructed on basis of CHENGZHUANG Mineg geological condition, and the distributions of gas pressure in the surrounding of hole were educed by making use of numerical simulation, and the effective pressure-released radius of gas drainage was obtained by the critical pressure ; the data of gas drainage were analyzed.
