摘 要:随着近些年矿井开采埋深的增大,突出矿井的非突煤层也逐渐转变为突出煤层,煤与瓦斯突出事故频繁发生。针对这一问题,以贵州省文化矿为例,结合该矿井瓦斯地质规律特点,对影响该矿煤与瓦斯突出的主控因素进行了分析,对深部未开拓巷道的瓦斯压力、瓦斯含量进行公式推导,确定了该矿埋深大于243 m,瓦斯含量大于8 m3/t的区域为突出危险性区域。该预测方法可以方便矿方对煤层深部做煤与瓦斯突出鉴定的重点区域进行重点分析,加密测压钻孔的布置,提高煤与瓦斯突出鉴定的准确率;同时可以指矿方在巷道施工前对这些重点区域采取必要的局部防突措施,对减少灾害事故的发生具有重要意义。With the increasing mining depth of mines, outburst mines with non-outburst coal seam changes into outburst coal seam, with frequent coal and gas outburst accident. Based on this problem, Wenhua Mine of Guizhou Province was taken as example, combined with the gas geology law features of the mine, the main reason of causing coal and gas outburst was analyzed, gas pressure and gas content of deep and not mining roadway were deduced by formula, the mining depth is larger than 243 m, area gas content larger than 8 m3/t is outburst danger area. The prediction method could facilitate the analysis of coal and gas outburst identification of deep coal seam, Infill drilling pressure, improve the accuracy of identification of coal and gas outburst; guide the precaution of outburst before mining, which exerts great significance of reducing disaster.
