黄庄勘查区二_1煤层瓦斯赋存规律及控制因素分析
|
摘要
针对黄庄勘查区二_1煤层埋藏较深、煤层稳定、结构简单,但瓦斯含量较低,并且分布不均衡,瓦斯含量差异较大,局部形成瓦斯聚集区的问题,对瓦斯赋存规律及控制因素进行研究。研究表明勘查区地质构造、煤层围岩是导致勘查区瓦斯含量相对较低的主要原因,地质构造、煤层埋深、煤厚是影响煤层瓦斯赋存形态的主要因素。研究瓦斯赋存规律,对防止煤与瓦斯突出、消除或降低煤与瓦斯突出事故造成的危害有很好的指导意义。
In allusion to issues of coal seam deep buried depth,steady,structurally simple,but rather low gas content,unevenly distributed,larger gas content difference and locally formed gas accumulation of coal Ⅱ_1 in the Huangzhuang exploration area,have carried out researches on gas hosting pattern and controlling factor. The study has shown that the geological structure and coal seam adjoining rock are the main causations of relatively low gas content in the area; while the geological structure,coal buried depth and thickness are the main factors impacting coal seam gas hosting configuration. The study on gas hosting pattern has good guiding significance to prevent coal and gas outburst,eliminate or lower down coal and gas outburst accident caused hazards.
