| 摘 要： | 为研究地质因素对煤层瓦斯赋存的影响,针对淮北矿区石台煤矿3煤层,采用瓦斯地质块段划分的方法,以井田内主要断层和天然焦区为界,把3煤层划分为3个独立的地质块段,分区对不同地质块段内地质因素对煤层瓦斯赋存规律进行研究,分析褶皱构造、断裂构造及岩浆侵蚀等对煤层瓦斯压力和瓦斯涌出量的影响。结果表明:地质构造对瓦斯保存和运移起到重要作用,岩浆岩侵入对石台煤矿3煤层煤与瓦斯突出的控制作用最为明显,地质块段的划分(分区管理)对地质构造复杂的高瓦斯及煤与瓦斯突出矿井具有重要意义。

| Abstract: | In order to research the influence of geological factors on gas bearing in coal seam,taking No.3 coal seam of Shitai coal mine for example and the main faults and mineral coke area as a border,the No.3 coal seam was divided into three separate geological unit by the use of gas geology segments dividing method.Then the influence of geological factors on the law of gas storage was researched according to different geological block,and the effects of folded structures,faulted structures and magma erosion on ga... |
