| 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 factor interaction matrix and the analysis on influencing factors of goaf RD, 12
main influencing factors of goaf RD were chosen, and an multi-factor interaction matrix model of goaf RD
was established. The interaction weights of each influencing factor were determined through expert
scoring method. The influence value of influencing matrix on single factor and the influence value of
single factor on matrix system were obtained, thus the influencing weight table of goaf RD factors was
acquired. After analyzing the influencing weight table, it showed that the factors with the maximum
influence on goaf was the pillar size and distribution, and the rock mass fracture and damage zone. The
goaf RD was classified by using the difference method, and the classification dia-gram of goaf RD was
obtained. Through example verification, the evaluation results of interaction matrix presented good
agreement with the actual situation, which showed that it is feasible to evaluate the RD of goaf area by
using the influence matrix method. It has practical application value, and is worth a wide promotion in
practical mine engineering. |
