我国是世界上最大的产煤国,也是发生煤矿事故最严重的国家,煤气层灾害就是造成我国煤矿事故的主要原因,而煤气层抽放则是防治煤矿煤层气灾害事故的根本措施。近来来,煤炭工业迅速发展,矿井数量迅速增加,并且很多低煤层气矿井变为高煤层气矿井和突出矿井,越来越多的矿井需要抽采煤气层,因此,迫切需要煤气层抽采技术的迅速发展与有效应用。本文通过分析煤层气抽采的重要意义,针对我国煤层气抽采的技术展开了讨论,并总结出了一些煤层气抽采的技术要点与安全技术措施,希望对煤层气的抽采技术研究工作有所帮助。
China is the largest coal producer in the world and also the country with the most serious coal mine accidents. Gas layer disaster is the main cause of coal mine accidents in our country. Gas drainage is the fundamental measure to prevent coal mine methane disaster. In recent years, with the rapid development of the coal industry, the number of mines has increased rapidly. Many low-coalbed methane mines have become high-coalbed methane wells and prominent mines. More and more mines require the extraction of gas layers. Therefore, there is an urgent need for gas- The rapid development and effective application. Based on the analysis of the significance of coalbed methane extraction, this paper discusses the technologies of coalbed methane extraction in China, and summarizes some key technical points of coalbed methane extraction and safety technologies. It is hoped that the research on extraction technology of coalbed methane Help
