摘要
根据瓦斯抽采有效半径测定方法的研究现状及各种方法优缺点的分析结果,提出残余瓦斯含量法测定抽采有效半径,并以林华煤矿9号煤层为例进行了现场测定,得到不同抽采时间对应的抽采有效半径,为合理布置抽采钻孔间距提供了科学依据,提高了瓦斯抽采效率,降低瓦斯抽采成本。
According analysis results of research status of gas extraction effective radius assay method and merits and demerits of allkinds methods, and gas extraction effective radius with residual gas content method measured was put forward, and it taking No. 9 coalseam of Linhua coal mine as example, then extraction effective radius that correspond with different extraction time, it referenced forreasonable layout of gas extraction holes space, gas extraction efficiency was improved obviously, and then extraction cost was reduced.
