| Abstract: | Applying smooth blasting of fan shaped medium length holes in underground mining.it can control underground pressure,safeguard the stability of stope empty and reduce ore loss rate and dilution rate.This technology has developed the drilling way of smooth blasting into the fan shaped medium length holes,as a result,the smooth blasting can be used in a new field.It proved from experiment that it is feasible.So this successful experience is worthy to be popularized. |
