| Abstract: | The effect of rock tunnel shallow hole blasting is not satisfactory with the low utilization rate of porthole, tunnel poor shape, materials, great loss. Blasting back with smooth blasting technique can improve the utilization of boreholes and work efficiency, improve the construction safety factor to achieve high production and efficiency of mine. |
