It researches two key skills of pumping water power station underground digging as well as top-arch pouring steel fiber concrete constructing ratio,fixes digging construction plans and optimized hole layout and bursting parameters through digging simulating tests,so as to reduce the damage of rock and quaking effect.

The layout of drill hole and the determination of parameter in advanced water injection to prevent rockburst from occurring;

Based on the experiment of fan-shaped blasting of sublevel caving method in Beiminghe iron mine,the paper analyzed the factors of affecting to blasting effect,optimized the blasting parameter,and selected logical layout of the blasting bores.

An example of the application of vee cutting blasting technology in the cutting excavation of a certain highway in Anhui Province is introduced in this paper, and the design of blast-hole arrangement, blasting parameters, initiating network,stemming and safety measures are presented.
