15113综采工作面初采期间瓦斯治理研究

Study on Gas Control During Primary Mining of 15113 Fully Mechanized Coal Face

15113综采工作面初采期间,由于老顶未垮落,造成工作面上隅角瓦斯偏高。通过采取调整15113高抽巷流量、上隅角埋设花管抽采瓦斯、上下端头及时退锚、上下隅角打设挡墙等措施,顺利治理了15113工作面上隅角的瓦斯。

During the initial mining of 15113 fully mechanized coal face,the gas in the upper corner of the face is on the high side because the old roof is not collapsed.The gas in the upper corner of 15113 working face was successfully controlled by adjusting the flow of 15113 high drainage roadway,burying flower tubes at the upper corner to extract gas,retreating the anchor at the upper and lower ends in time,and setting up retaining walls at the upper and lower corners.
