摘要
寺河矿西井区是煤与瓦斯突出矿井,根据煤层瓦斯地质条件,西井区将预抽煤层瓦斯作为区域性防突措施。本文论述了首采工作面的区域消突措施,采用煤层残余瓦斯压力法、残余瓦斯含量法和综合指标(D值)法对工作面区域消突效果进行了检验分析。
Western area of Sihe Mine has coal and gas outburst.On the ground of geological condition of coal-bed methane,gas pre-drainage was used as regional outburst prevention.The paper presents the regional outburst elimination measures in the first mining face.Residual gas pressure method,residual gas content method,and comprehensive index(D value) method were used to study the regional outburst elimination effect.
