摘要
磷矿开采过程中诱发的地压已严重影响了矿山安全生产,开展磷矿地压稳定评价是保障安全生产的重要内容之一。以位于湖北宜昌的神龙磷矿典型矿区为研究对象,首先分析总结了神龙磷矿矿区的岩体结构特征和地压危害形式,并在此基础上构建稳定性评价指标体系,接着利用组合赋权法将层次分析法和基于指标相关性的指标权重确定法有机结合获得最优权重,再结合云模型计算评价指标的数字特征值,最后根据稳定性分级评价集得到稳定性评价结果。完成了4个分区的地压稳定性评价,通过进一步现场核对,评价结果与实际观测结果一致,说明提出的评价指标和评价模型在磷矿地压评价中有较好的适用性,对指导磷矿安全生产具有参考价值。
Mining-induced ground pressure of phosphate mine has seriously affected the safety of mine production.Evaluation of ground pressure stability in phosphate mines is one of the most important elements to ensure safe production.This paper takes a typical mining area of Shennong phosphate mine located in Yichang,Hubei Province of China as a research case.First,a summary of characteristics of rock mass structure and forms of ground pressure hazard in Shenglong phosphate mine was presented.On this basis,a stability evaluation index system was constructed.Then a combination weighting method was used to combine analytic hierarchy process with criteria importance through intercriteria correlation to obtain optimal weight.And digital eigenvalues of evaluation index were calculated according to cloud model.Finally,stability evaluation results were obtained according to stability grading evaluation set.Ground pressure stability evaluations of four zones were completed,respectively.Through verification,the evaluation results are consistent with that of actual observation.It shows that the evaluation metrics and evaluation models presented in this paper are well suited for evaluation of the ground pressure in phosphate mines.It is useful to guide safety production of phosphate mines.
