摘要
合理的瓦斯防治措施,对有效减少瓦斯事故的发生具有重要意义。为了实现研究区瓦斯的有效抽采,在对研究区构造特征、瓦斯特征、煤层特征等进行分析的基础上,结合研究区采掘进度安排,提出集危险性预测、抽采措施、效果评价为一体的瓦斯综合防治措施。并在阜生矿1103运输巷采掘面进行现场实施,实施结果表明:通过有计划抽采后,煤层瓦斯含量降低至8m3/t以下,达到了抽采目的,体现了该防治措施的可行性,可为临近区掘进面瓦斯抽采提供参考。
Reasonable gas control measures are of great significance to reduce the occurrence of gas accidents.In order to realize the efficient extraction of gas in the study area,the structure characteristics,the gas characteristics,characteristics of coal seam and so on were analyzed.At the same time,taking into account the progress of the mining area,a comprehensive prevention and control method including the risk prediction,extraction measures and the evaluation of the effect of extraction was put forward.The method was carried out in the1103transport roadway,and the results showed that the gas content of the coal seam was reduced to below8m3/t,and the purpose of pumping was achieved through the planned extraction.This shows the feasibility of the control measures,and provides a reference for the gas extraction in the adjacent area.
