地面煤层气井定向消突与负压抽采试验

Test of Orientated Elimination Outburst and Negative Pressure Extraction in Ground Coalbed Methane Wells

叙述了煤矿利用的地面定向消突新工艺及新技术,并结合工程实例对其进行了分析,指出对其的应用提升了突出矿井的瓦斯灾害治理水平,通过地面煤层气设备的二次利用,降低了矿井瓦斯抽采的成本,又能获得良好的经济和社会效益。

This paper described the new process and new technology of ground directional outburst elimination used in coal mine,made related analysis combined with engineering project example, and pointed out that its application enhanced the governance level of gas disaster in outburst mine. Secondary utilization of the ground coalbed methane gas equipment can reduce the mine gas extraction cost, and can obtain good economic and social benefits.
