Abstract:
Positive outburst elimination technology is commonly used in the traditional method of outburst elimination uncovering coal in mine shaft. Because of the restrict of construction space of mine shaft, there are the problems such as the difficulties of drilling rig moving and fixing, as well as water and slag drainage is not easy in the construction, which affects the construction schedule, etc. Aiming at these problems, reverse outburst elimination technology for uncovering coal in mine shaft is proposed,the roadway near the mine shaft underground is used to arrange the gas drainage hole, and conduct the gas drainage in the area of uncovering coal in mine shaft to eliminate the dangerous of coal and gas outburst. Through the field application, it achieves good results.
