摘要:
准确评估采空区边坡的安全性能,对于保障矿山安全生产具有重要意义,为解决采空区边坡安全性评判时过程繁琐且准确性较低的问题,采用TOPSIS理论建立了采空区边坡的危险性评判模型。首先考虑各影响因素的不确定性和关联性,采用HHM方法从孕灾环境、致灾因子和承灾体方面来构建多层次评价指标结构体系;然后引入变异系数法改进原有的TOPSIS方法,弥补了其逆序现象问题所带来的误差;之后对采空区边坡危险性等级进行划分,通过相对贴近度构建出危险性等级判断的量化区间;最后将建立好的评价模型应用于具体工程实例中进行验证,并与常用方法的评价结果进行对比。研究结果表明:该模型评判结果与实际相吻合,可以很好的评判采空区边坡的状态,准确度高、评价结果更为科学,具有很好的适用性与合理性。对于提前辨析采空区边坡安全性能,及时治理边坡灾害,提供了一种可靠的新方法。
Abstract:
Accurately evaluation safety performance of goaf slope was of great significance to ensure mine production safety. In order to solve problems of tedious and low accuracy in the safety evaluating of goaf slope, TOPSIS theory was used to establish evaluation model. Firstly, the uncertainties and correlations of influencing factors were considered, and HHM method was adopted to construct a multi-level evaluation index structure system from aspects of the disaster-prevention environment, hazard-causing factors and disaster-bearing bodies. Then the coefficient of variation method was introduced to improve the TOPSIS and to remedy errors which caused by the problem of reverse order phenomenon. After that, the safety grades of goaf slope were divided and quantitative interval of safety grades judgment was constructed by relative closeness degree. Finally, the established model was applied to verify in the engineering project, and compared with the results of common evaluation methods. The research results show that the evaluation model is in good consistent with the actual goaf slope engineering state, and with high accuracy and rationality. The model provides a new and reliable method for identifying safety performance of goaf slopes and timely scientific managing slope disasters.
