摘要
以李子垭煤矿5102南工作面为实施对象,对急倾斜复合煤层采煤工作面抽采巷道的优化设计、预抽煤层瓦斯方法、抽采设备主要配置等瓦斯治理技术进行了实践研究,实现了急倾斜复合煤层采煤工作面瓦斯抽采达标和安全回采。
Based on the engineering background of5102south coal face in Liziya Coal Mine,the practical research on gas extraction roadway optimization and design,gas pre-extraction method,main configurations of extraction equipment and other gas control technologies for working face of steeply inclined multiple coal seam were conducted,which realized qualified gas extraction and safe mining in the working face with similar conditions.
