阳煤集团煤层瓦斯抽采技术的现状分析

为了提高阳煤集团本煤层瓦斯抽采效率，采用统计和对比分析方法，介绍了阳煤集团本煤层瓦斯抽采技术现状。分析表明，阳煤集团本煤层瓦斯年抽采量虽然已达1亿m^3但抽采效率还处于较低水平。需要进一步优化本煤层钻孔参数、提高钻孔封孔质量、强化抽采管路连接、搞好抽采系统日常维护，以使阳煤集团本煤层瓦斯抽采效率得到进一步提高。

Study on Seam Gas Drainage Technology in Yangquan Coal Group

To increase seam gas drainage efficiency,the gas drainage technology used in Yangquan Coal Group was studied by statistics and contrast analysis.The results showed that the drainage rate hadattained 0.1 billion m3 per year,but the efficiency was still at the lower level.The seam drilling parameters should be further optimized to increase drilling and sealing quality,strengthen drainage pipes linkage,and improve routine maintenance of drainage system in order to make further improvement on the drainage effic...
