露天转地下开采覆盖层界面移动规律初步分析

On primary analysis of interface movement law of overburden layer at open pit into underground mining

针对露天矿山转为地下开采亟待解决的覆盖层问题,通过实验模型,进行相似材料的模拟,求得覆盖层界面移动曲线,从而寻求了矿山覆盖层界面曲线的一般求法,为边帮爆破形成覆盖层提供指导性的建议。

According to the overburden layer which needs to be solved at the open pit into underground mining,the paper undertakes the simulation of the similar materials according to some experimental models,achieves the interface movement curve of the overburden layer,so as to obtain the general methods for the interface curve of the overburden layer in mining mountains,and provide some direction suggestions for the overburden layer by the side blasting.
