随着矿山事业的发展，露天矿规模不断加大，同时开采深度逐年加深，深层含水量变大，加之常年高爆破震动频数使浅表层节理裂隙发育，水的渗透能力增大，深凹露天排水困难等，在大气降水及深层含水的渗透作用下，露天矿水孔逐渐增多，爆破冲孔量随之增大，而冲孔使爆破效果变差，采剥作业受冲孔带来的影响愈来愈严重。

With the development of mining industry, the scale of open-pit mine is increasing. At the same time, the mining depth is deepening year by year, the deep water content is increasing. In addition, the high frequency of blasting vibration makes the shallow surface joints and fissures develop, the water permeability is increasing, and the deep open-pit drainage is difficult. Under the infiltration of atmospheric precipitation and deep water content, the water holes of open-pit mine are increasing gradually, and the blasting punching volume is increasing But the blasting effect is getting worse because of punching, and the influence of punching on mining and stripping operation is more and more serious.<br>
