【摘要】 影响采场稳定性的因素具有随机性、模糊性的特点,通过对各评价指标的定量分析,建立了采场稳定性综合评价模型,基于层次分析法(AHP)确定了采场指标权重,对采场稳定性进行了定量评价.运用FLAC3D对峄城区石膏矿采场受到开挖﹑流变﹑爆破扰动等因素影响的情况进行数值模拟,验证影响采场稳定性的因素所起作用的取值是否合理,经验证,基于层次分析法计算采场稳定性的指标权重合理可行.更多还原

【Abstract】 The stope stability could be affected fuzzily and randomly a comprehensive evaluation model of the stope stability was built by analyzing each evaluation index in quantitative.The index weight of the stope was determined,and the stope stability was evaluated in quantitative based on the analytic hierarchy process(AHP).Selecting the gypsum mine on Yicheng District,we used FLAC3Dto simulate the stope affected by excavation,rheology,blasting disturbance,and verified whether the value of the role for factors that influence the stope stability were reasonable. The results showed that the index weight calculation of mining field stability based on the AHP was reasonable.更多还原
