Method for judging mutual influence of open pit backfilling and underground mining

The invention aims to solve the technical problem of judging the mutual influence of open pit backfilling and underground mining, and provides a method for judging the mutual influence of open pit backfilling and underground mining. The method comprises the following steps that S1, the influence of open pit backfilling on underground mining is analyzed; and S2, analyzing the influence of underground mining on the side slope in the backfilling process of the open pit. According to the method, the three-dimensional numerical model of open pit filling and underground mining is constructed, and the mutual influence of open pit filling and underground mining is researched, so that the safety from open pit to underground mining is improved. 本发明要解决的技术问题是判定露天坑回填与地下开采协同的相互影响，提供了一种露天坑回填与地下开采相互影响的判定方法。该方法包括如下步骤：S1：分析露天坑回填对地下开采的影响；S2：分析地下开采对露天坑回填过程边坡的影响。本专利通过构建露天坑充填和地下开采的三维数值模型，研究露天坑充填与地下开采的相互影响，以提高露天转地下开采的安全性。
