摘要
为了掌握黄岩汇煤矿15号煤层瓦斯赋存规律及其突出危险性,通过井下实测瓦斯含量,运用地质构造控制理论分析了15号煤层瓦斯赋存特征及其影响因素,得出埋藏深度是控制15号煤层瓦斯含量变化的主导因素,煤层围岩对瓦斯保存起到了积极作用,断层、褶皱和陷落柱等因素对局部瓦斯分布有所影响.并在此基础上对15号煤层进行突出危险区划分,结果表明,该矿井15号煤层埋藏深度大于321m的区域为突出危险区,为防治瓦斯突出和矿井的安全生产提供了科学依据.
In order to master the gas deposit law and the outburst hazard of the No.15 coal seam in Huangyanhui coal mine,by measuring the gas content and using the geological structure,this paper this paper analysed the gas deposit law and the influence factors,obtained that the buried depth would be the significant factor to the change of the gas content,the surrounding rock played a positive role on gas preservation,the local area would be affected by the faults,the folds and the collapse columns.On the basis,outburst risk areas of the No.15 seam were divided,and the results showed that the coal seam would be the outburst risk area when the buried depth was over 321 m,and provided the foundation for preventing and curing the gas outburst and the safe production of the coal mine.
