Application of Hydraulic Punching Technology in Treatment of Outburst Coal Seam Gas by Drilling through Floor
In order to effectively improve the gas control effect of floor through layer drilling,taking the gas control of 3301 track transportation channel in A Coal Mine of Shanxi Province as the engineering research background,it was proposed to apply hydraulic punching technology to the floor extraction roadway through layer drilling of track transportation channel,and the engineering application effect was analyzed.After on-site application,the gas extraction efficiency of the floor through layer drilling significantly improved,effectively solving the problems of long time for gas suppression and gas control constraints on tunnel excavation,and creating favorable conditions for safe and efficient excavation of the 3301 track transportation channel.
