平邑县安泰石膏矿采空区稳定性综合评价方法

Comprehensive Stability Evaluation Method of Goaf in Antai Gypsum Mine in Pingyi County

摘要:

石膏矿采空区的治理难度大、成本高。为科学决策石膏矿采空区的防治措施，需要准确评价采空区稳定性。在分析各种石膏矿采空区稳定性评价方法的基础上，该文提出了一种联合应用综合评判法和矿柱安全系数法的综合评价方法。该文以平邑县安泰石膏矿采空区的稳定性评价为例，介绍了该综合评价方法的应用过程。综合评价结果表明，该采空区有7个分区处于不稳定状态，评价结果与地表观测结果吻合较好。实践表明，该综合评价方法评价过程简便，评价结果准确，可以为其他石膏矿采空区稳定性评价提供借鉴。

Abstract:

The treatment of goaf in gypsum mine is very difficult with high cost. In order to make a scientific decision on the prevention and controlling measures of the goaf in gypsum mine, the stability of the goaf needs to be accurately evaluated. Based on the analysis of the stability evaluation methods in various gypsum mine mined out areas, a comprehensive evaluation method which will combine the comprehensive evaluation method and the pillar safety factor method together is put forward in this paper. Taking the stability evaluation of a gypsum mine goaf as an example, the application process of the comprehensive evaluation method is introduced. As showed by the comprehensive evaluation results, 7 subareas in the goaf are in unstable state. The evaluation results are in good agreement with the surface observation results. It is showed that the evaluation process of the comprehensive evaluation method is simple and accurate. It will provide some references for the stability evaluation of other gypsum mine goaf.
