【Abstract】 Using controlling blasting and short-delay blasting theory,aiming at fast carving out a new level in a strp mining,controlling blasting flying rocks and vibration were caused by blasting.Through analysis and contrast,one feasible project was brought out.The outcoming show that the project guarantee time-limit of the project and the safety of the nearly constraction.Also,the blasting cost was reduced.更多还原
