【摘要】：基于因子交互作用影响矩阵及采空区危险度影响因子分析,选取12个采空区危险度主要影响因子,建立采空区危险度多因子交互作用矩阵模型。通过专家打分法,确定各影响因子相互作用权值,得到影响矩阵对单一因子的影响值及单一因子对矩阵系统的影响值,从而得出采空区危险度因子影响权重表。分析影响权重表,得到对采空区影响最大的因子为矿柱尺寸及分布和岩体断裂及破损带。采用差值法,对采空区危险度进行等级划分,最后得到采空区危险度分级图。经过实例验证,影响矩阵法分析评价结果与实际吻合,表明采用影响矩阵法评价采空区危险度是可行的,具有实际应用意义,可在实际矿山工程中应用推广。
[Abstract]:Based on the analysis of the influence matrix of factors interaction and the risk degree of goaf, 12 main influencing factors of risk degree in goaf are selected, and the multi-factor interaction matrix model of risk degree in goaf is established. The interaction weight of each influence factor is determined, the influence value of the influence matrix on the single factor and the influence value of the single factor on the matrix system are obtained, and the influence weight table of the risk factor in the goaf is obtained, and the influence weight table is analyzed. The most influential factors on goaf are the size and distribution of pillar and the fracture and breakage zone of rock mass. The danger degree of goaf is classified by difference method. Finally, the classification map of risk degree of goaf is obtained. The result of analysis and evaluation by the influence matrix method is in agreement with the actual situation, which indicates that it is feasible to use the influence matrix method to evaluate the risk degree of goaf, which has practical application significance and can be applied and popularized in actual mine engineering.
