矿山开采地表动态下沉预计分析

Prediction analysis of dynamic subsidence of mining surface

随着经济的发展,对各类矿产资源的寻求也在不断增加,这就使得矿山在开采深度在不断加大、加深。同时,随着开采深度的增加,当开采作业达到一定深度之后,就会出现明显的地表动态下沉现象。本论文就是以矿山开采地表动态下沉为出发点,通过分段函数的方式,分别对矿山开采过程中,以及矿山开采停止后,地表的动态下沉过程,进行了详细的分析,并提出了地表动态下沉预计的计算方法。

With the development of economy, the search for various types of mineral resources is also increasing, which makes the mining depth is increasing and deepening. At the same time, with the increase of mining depth, there will be obvious dynamic subsidence of the ground surface. This paper is to mining dynamic subsidence of the ground surface as the starting point, through the function, respectively in the process of mining, and the mining stopped, surface subsidence process, carried out a detailed analysis, and put forward the dynamic surface subsidence forecast calculation method.
