摘要
为实现瓦斯灾害的有效防治,以登茂通煤业2210工作面为工程背景,采用本煤层预抽和采空区压管抽放的方法进行瓦斯抽采。基于此,设计了2210工作面瓦斯抽采钻孔布置参数和瓦斯抽采系统。采用本煤层瓦斯预抽后,进行了瓦斯抽采达标评判,经评判,登茂通煤业2210工作面煤层瓦斯各项指标均达到规定要求,达到评判指标。
In order to realize the effective prevention and control of gas disaster,taking the 2210 working face of Dengmaotong Coal Mine as the engineering background,the 2210 working face adopts the methods of coal seam predrainage and goaf pressure pipe drainage to carry out gas drainage.Based on this,the gas drainage borehole layout parameters and gas drainage system of the 2210 working face are designed.After using the gas pre-drainage in this coal seam,the gas extraction standard is evaluated.After evaluation,all the indexes of coal seam gas in the 2210 working face of Dengmaotong Coal Mine meet the prescribed requirements and reach the evaluation index.
