| Abstract: | In the mine laneway with coal and gas outburst, outburst prevention measures determined excavating velocity and construction safety. The mechanism of secondary slot high pressure water injection was introduced in this article. Combine with the effect of this outburst prevention measure applicated in Lunan 3 # mine lane- way in Xinjing Cola mine, we concluded the important guidance function of secondary slot high pressure water injection in coal and gas outburst laneway. |
