中文摘要：
岩体稳定性评价是矿山选择采掘方法和支护措施的重要依据。根据围岩的结构特征和矿山地质环境,选取了抗压强度、岩石质量指标、节理间距、节理状况、地下水状况和地应力状况6个影响因素,基于未确知测量理论,建立矿山围岩稳定性评价模型。根据矿山围岩的实测数据,建立了适合各影响因素的未确知测度函数,并对其进行定量分析,利用熵计算各影响因素的指标权重,根据置信度识别准则对岩石稳定性等级进行判定,该方法较传统的模糊数学和灰色理论等评价方法有诸多优点,该方法可对研究对象进行定量描述,更具客观性和科学性。
英文摘要：
The stability valuation on the rock mass is the important base to select mining method and supporting measure for mines. According to the structure characteristics of surrounding rock and the geological environment in mines, the six factors of compressive strength, rock quality index, joint space, joint condition, groundwater condition and in-situ stress are selected to evaluate the rock stability. The model of surrounding rock stability evaluation in mines was established based on the unascertained measure theory. According to measured data of the mine surrounding rock the unascertained measure function suit to each factor is established. With quantitative analysis the index weight of each affecting factor is calculated by entropy, and according to the confidence recognition criteria the level of rock stability was determined. This method has many advantages compared with the traditional theory of fuzzy mathematics and grey theory, is more objective and scientific.
