摘要
随着区域防突措施的实施,困扰煤矿更多的是实施抽采钻孔期间的瓦斯异常涌出问题。焦煤公司九里山矿在对打钻作业环节瓦斯异常涌出来源进行分析的基础上,制订了有效的预防和控制措施,该措施的应用取得了明显的效果。
With the implementation of regional outburst measures, the problems affected coal mine are mainly abnormal gas emission phenomena during drilling. On the basis of analysing the sources of abnormal gas emission, effective control and prevention countermeas- ures were drawn up, the application of these measures has achieved obvious effects.
