摘要
基于瓦斯地质学理论,探讨了平煤六矿瓦斯地质规律,分析了地质构造、煤层埋深、围岩及煤层厚度、水文地质等因素对瓦斯赋存的影响,以及地质构造、煤层厚度的变化和煤体结构等因素对煤与瓦斯突出的影响。结果表明地质构造是控制平煤六矿煤层瓦斯赋存和煤与瓦斯突出的主要因素。在此基础上制定了防治煤与瓦斯突出的针对性措施,采用分源立体瓦斯综合抽放技术进行瓦斯抽放,瓦斯预测与动态瓦斯预警相结合,为矿井安全生产提供了保障。
Based on the theory of mining gas geology, the gas geological law in No. 6 Mine was discussed, and the effect of geological structure, coal seam burial depth, thickness of sur rounding rocks and coal seams, hydrogeology on the gas occurrence were analyzed, as well as the influence of geological structure, coal seam depth and its variation, and coal mass structure on the coal and gas outburst. The results showed that the geological structure is the main factor to influence the gas occurrence and gas outburst. So the corresponding measures were decided to control the gas by 3D comprehensive gas drainage technology according to different sources, the combination of gas forecast and dynamic gas early warning, providing a guarantee to the safe production of coal mines.
