露天煤矿境界内地下采空区稳定性影响因素研究

Research on stability influence factors of underground goaf in Open-pit Coal Mine

围绕地质条件及岩体力学性质、采空区空间尺寸参数以及露天开采活动等3个方面,对露天矿采空区稳定性影响因素的种类、影响程度以及影响机制展开较深入的分析,并以采空区稳定性的安全系数评价法为例来说明这些影响因素的重要性与作用路径,目的是在采空区评价与治理过程中能够抓住主要因素,兼顾次要因素,做到科学合理、切合实际的进行处理与取值。

This article analyzes the kinds of influence factors, the influence degree and influence mechanism surrounding the geological conditions and the nature of the rock mass mechanics, the size parameters of goaf and the open-pit mining activities three aspects. The author illustrates the importance of these factors and the path by the safety factor evaluation method, in order to seize the main factors, the secondary factors and achieve the scientific, reasonable and practical targets in the process of evaluation and management.
