摘要
为开采解放层采用了专用排瓦斯巷、高位抽放尾巷、高位钻场、高抽巷、底抽巷等先进瓦斯治理技术,并通过回采时对该采面的瓦斯变化、瓦斯地质情况、瓦斯来源及瓦斯抽放的参数进行总结、分析,及时提出改进措施、办法。为瓦斯含量高、层间距较近的煤层群开采解放层,提出了多方位的瓦斯综合治理措施,为有效治理瓦斯提供了宝贵经验。
In order to mine protective seam, gas drainage roadway, high level roadway, high level drilling site,overlay gas extraction roadway, bed plate roadway etc advanced gas control technology are used. Gas control measures are put forward by gas change, coalbed gas geology, gas resources and gas drainage parameters, and gas comprehensive management valuable experience is obtained for high gas and close distance coal seam group mining.
