Quality and Efficient Tunneling Technology in Xin San Mine

Abstract:

The efficiency of our rock roadway is generally not high, January footage is generally around 60m, which greatly affected the normal mine production mining to succeed. Optimize the blasting parameters, support technology and strengthen the construction organization and management measures is to solve the Rock Lane embrasure low utilization rate, blasting the poor, loop footage and low problem. The experiments show that: the three new mines using the above measures, the rock roadway construction speed from the original 60 m per month to 120 m / month, improve efficiency of 100% quality and efficient excavation of the rock roadway to reach the test purpose. Of the success measures and methods to provide reference for other similar mine rock roadway quality and efficient construction.
