腾晖煤业2-205综放工作面瓦斯治理技术研究

Study on Gas Control Technology of 2-205 Fully Mechanized Caving Face in Tenghui Coal Industry Co.,Ltd.

以腾晖煤业2-205综放工作面为工程背景,针对工作面瓦斯含量高的问题,综合采用本煤层钻孔、上隅角插管及高低位裂隙钻孔抽采3种抽采方式进行瓦斯治理。对该工作面的瓦斯治理技术进行了讨论。现场工程实践效果表明,2-205综放工作面的瓦斯抽采率可达到54.9%,工作面通风能力可满足风排瓦斯的需求,治理效果明显。

Taking 2-205 fully mechanized caving face of Tenghui Coal Industry Co.,Ltd.as the engineering background,aiming at the problem of high gas content in the working face,this paper comprehensively adopted three drainage methods of coal seam drilling,upper corner intubation and high and low fracture drilling to control gas.It discussed the gas control technology of the working face.The field engineering practice results showed that the gas drainage rate of 2-205 fully mechanized caving face could reach 54.9%,the ventilation capacity of working face could meet the demand of air exhaust gas,and the control effect was obvious.
