煤矿工作面瓦斯综合治理技术研究

Research on gas comprehensive management technology on coal mine workplace

介绍了亭南煤矿建立局部瓦斯抽放系统对101工作面进行瓦斯抽放情况，采用采面上隅角抽放、采前预抽、掘进预抽等抽放方法对亭南煤矿101工作面进行综合治理。通过对综采工作面及掘进面的瓦斯治理，摸索出一套适合于石泉煤矿4#煤层赋存条件及开采条件的瓦斯治理技术，为今后矿井的瓦斯治理提供可靠的依据。

This paper introduced the situation of gas suction on 101 workplace of Tingnan Coal Mine by building up local gas suction system. Gas suction from the upper comer, gas predrainage before mining and driving were used to manage the 101 workplace comprehensively, and after these management, a set of suitable gas control technology for No.4 coal seam occurrence and mining conditions of Shiquan mine was sought out, and which provided reliable basis for the future mine gas management.
