摘要
马兰矿18502工作面回采期间瓦斯来源主要为本煤层瓦斯和下邻近层瓦斯,利用运料巷、运输巷抽采本煤层瓦斯,利用底抽巷抽采下邻近层瓦斯,利用高抽巷抽采裂隙带瓦斯,采用悬管抽采回风隅角瓦斯,保证了工作面的安全高效开采。
During the stoping period of 18502 working face of Malan Mine, the gas source was mainly coal seam gas and lower adjacent layer gas. The author proposes that haulage lanes and transportation lanes be used to extract gas from this coal seam,bottom-drainage lanes be used to extract gas from adjacent layers, high-drainage lanes be used to extract gas in fissure zones,and suspended pipes be used to extract gas from the corners of the wind, which ensures the safe and efficient mining of the working face.
