矿井瓦斯抽放系统可行性分析与预抽技术研究

Feasibility Analysis on Mine Gas Drainage System and Research on Gas Pre-drainage Technology

通过对矿井瓦斯涌出特征、瓦斯储量和可抽量的预计分析,论证了朱仙庄矿新建南部瓦斯抽放系统的必要性和可行性,分别对矿井南翼丰富的瓦斯储量、矿井目前具有的抽放技术和抽放经验以及主采煤层可抽性等条件进行了分析,结果表明建立南部瓦斯抽放系统是可行的。并在此基础上对建立矿井瓦斯抽放系统的抽放技术进行了总结说明。

Based on the prediction and analysis of the emission characteristics, the reserve and drainable volume of the mine gas, the necessity and feasibility of the newly - built southern gas drainage system in Zhuxianzhuang coal mine were analyzed. The rich gas reserve in the south area of the mine, the used drainage technology, gained experiences in gas drainage and the possibility of gas drainage for the main mining seam were analyzed. The resuits showed that the newly -built southern gas drainage system is feasible. And on this basis, the drainage technology for establishing mine gas drainage system was summarized and explained.
