Study and application on cutting technology of underground drifting blasting Xiantang Zhanga, Peng Zoub, Hongmin Zhouc, Hongli Wangd Shandong Provincial Key Laboratory of Civil Engineering Disaster Prevention and Mitigation, Shandong University of Science and Technology, Qingdao, Shandong 266590, China azzxhtm@163.com, bkdzoup@163.com, chongminzhou@163.com, dskdwhl@163.com Key Words: Drifting, Blasting parameter, Cutting； Abstract: Because of the weak borehole sealing and inadequate use of the initial free face, the higher investment and unsatisfactory blasting effect still exist in the mine tunnel excavation blasting.
Due to the influence of rock roadway section, the depth of wedge cutting has been extremely limited, while increasing the number of shooting and auxiliary time like the time of hide the gun, not only lowing the efficiency, but also increasing the consumption of human and material resources, so increasing the cost of rock drivage.Coupled with the blast hole jams rickety and the initial free surface is underutilized, tunneling excavation blasting efficiency of underground drift is 65% to 68%.
