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

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 results 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.
