The shoot of high speed video camera and the technology of image manipulation are applied to test and study bubble pulsation parameters according to the optical visibility of underwater blasting. The track of bubble diameter changing with time and the pulsation period of 0.3g DDNP charge are obtained. 利用水下爆炸的光学可见，在浅水水体外将CCD高速摄像机实拍和图像处理技术引入了气泡脉动参数的测试研究，得到了0.3gDDNP装药的气泡半径随时间变化轨迹和脉动周期。

This practice showed that it was quite necessary to monitor blasting seismic effects and to regard the effects of blasting vibration on people in the blasting operated near large residential areas with a long period. 实践表明，在临近大型居住区进行长时间爆破作业时，进行爆破地震效应监测，并适当考虑爆破震动对人的影响是十分必要的。

If watertight stratum is destroyed during blasting period, the entry of large quantity of water and filling material into the tunnel may cause sudden, large-scale water gush and projection of mud soil. 如果隔水层在爆破过程中被破坏，大量岩溶水和填充物进入隧道可能会造成突发性大规模涌水突泥事故。

The two-phase flow mechanics and Runge-Kutta's four stages difference interation method were used to simulate blasting soot behaviors in impulsive and mushroom period. 基于建立的气固两相流动方程，运用四阶Runge-Kutta差分迭代算法，对冲击及蘑菇云阶段的烟尘时实行为进行了模拟；

The vibration velocities of the ground resulting from relief, breast and trim holes blasting do not always become greater with the increase of their single period charges; 辅助孔、崩落孔和周边孔爆破引起的地表振动速度并不总是随着其单段装药量的增加而增大；
