【摘要】：开滦集团吕家坨煤矿5831皮带石门、5832轨道石门以及它们之间的联络巷,在井下工人掘进的过程中,突然出现瓦斯涌出量过大的问题,严重影响了井下工人的身体健康和矿井的安全生产。通过对开滦集团吕家坨矿5831皮带石门、5832轨道石门以及12煤层进行现场相关资料的收集、整理,分析出其瓦斯赋存的多种影响因素,找出各种因素影响瓦斯赋存的原因。然后,根据现场瓦斯赋存及涌出的具体实际情况,研究瓦斯赋存原理。同时,对其临近的12煤层以及5831皮带石门与5832轨道石门岩巷之间的联络巷进行瓦斯压力的测定以及瓦斯相关参数的测定与研究。最后,采取风排瓦斯、抽放瓦斯、煤层注水等多种措施治理吕家坨矿5831皮带石门、5832轨道石门以及它们之间的联络巷瓦斯涌出量过大的问题,通过防治效果的考察与分析,这几种方法很好的达到了降低瓦斯浓度的效果,对矿井现场瓦斯防治的研究具有一定的参考价值。
[Abstract]:Kailuan Group Lujiatuo Coal Mine 5831 Belt Stone Gate No. 5832 track Shimen and the contact lane between them, in the process of digging underground workers, there is suddenly a problem of excessive gas emission.Seriously affected the health of underground workers and mine safety production.Based on the collection and collation of the related data of 5831 belt Shimen No. 5832 track Shimen and 12 coal seams in Lujiatuo Mine of Kailuan Group, this paper analyzes the various influencing factors of gas occurrence, and finds out the reasons for the influence of various factors on the gas occurrence.Then, according to the actual situation of gas occurrence and emission, the principle of gas storage is studied.At the same time, the gas pressure and gas related parameters are measured and studied in the adjacent 12 coal seam and the connection roadway between 5831 belt stone gate and 5832 track Shimen rock roadway.Finally, some measures such as air gas drainage, gas drainage and coal seam water injection are adopted to control the problem of excessive gas emission from 5831 belt stone gate track Shimen 5832 in Lujiatuo Coal Mine and the contact roadway between them, and through the investigation and analysis of the prevention and control effect,These methods have achieved the effect of reducing gas concentration, and have certain reference value to the study of gas prevention and cure in mine field.
