| Abstract: | In this paper the detonating time difference is known as a important factor to interfere with blast effect,and the optimal detonating time defference is 200-250 milliseconds in conditions of existing blast materials in our country by overall analysing the blasting efficioncy, size of blasting pieces and the affect of blasting quake for the stability of surrounding rock according to measurring data of mine situation and investigate results. |
