单一煤层以孔代巷区域瓦斯治理技术研究及应用

Research and Application of Gas Control Technology in Single Coal Seam with Hole Replacing Roadway

通过对我矿井进行地质抽样并进行精确分析的基础上,将千米定向钻机运用在煤层顶板中进行超长钻孔的施工工作。此外,还可以通过应用气驱增产技术来达到高效抽采瓦斯的目的,同时,将可靠有效的区域抽采达标评价技术应用到高效抽采瓦斯的工作当中,最终实现底板岩石抽采巷被长钻孔抽采技术所代替的目的,从而使煤巷条带瓦斯治理的区域防突措施能够得到很好的执行。这一替代方法降低了瓦斯的治理成本,使工作面的掘进进度得以加快,并且有效解决了能源接替紧张的问题。

On the basis of geological sampling and accurate analysis in our coal mine,the kilometer directional drilling rig is used in the construction of super-long drilling in the roof of coal seam.In addition,it can also achieve the goal of efficiently extracting gas by applying gas flooding stimulation technology.At the same time,the reliable and effective evaluation technology of regional drainage standards is applied to the work of highefficiency gas extraction,to achieve the purpose of replacing the floor rock extraction roadway with the long-hole extraction technology finally,so that the regional outburst prevention measures for strip gas control in coal roadways can be well implemented.This alternative method reduces the cost of gas control effectively,speeds up the tunneling progress of the working face,and solves the problem of energy shortage effectively.
