煤层气俗称瓦斯,相对于煤矿安全而言是一大灾害。但作为一种新型能源和洁净能源,它是常规天然气最现实的补充和替代。因此,加强瓦斯治理,加快煤层气开发,对于改善煤矿安全状况,调整煤炭产业结构,保护大气环境,培植新的经济增长点,具有重大的现实意义和深远的战略意义。山西焦煤集团屯兰矿“2·22”瓦斯爆炸事故,再次为人们敲响了警钟。人们不禁要问:是什么导致煤矿瓦斯爆炸事故时有发生?是什么阻碍了煤层气的开发利用?先抽后采能否解决根本问题?……
Coalbed methane, commonly known as gas, is a disaster relative to coal mine safety. But as a new type of energy and clean energy, it is the most realistic addition and replacement of conventional natural gas. Therefore, strengthening gas control and speeding up CBM development are of great practical significance and far-reaching strategic significance for improving the coal mine safety status, adjusting the coal industry structure, protecting the atmospheric environment and cultivating new economic growth points. Shanxi Coking Coal Group Tunlan mine “2.22” gas explosion, once again sounded the alarm for the people. People can not help but ask: What led to coal mine gas explosion accidents happen? What is hindering the development and utilization of coalbed methane? The first pumping after mining can solve the fundamental problem? ......
