| 摘 要： | 采用模糊综合评价方法对龙门山矿区L23矿体采场宽度12m、13m、14m三种方案进行优选。通过建立采场结构参数的层次分析模型及其隶属度矩阵,结合现场调查确定技术指标和经济指标,并应用FLAC3D数值模拟获得最大主应力、剪应力、顶板位移等6个安全指标;采用熵值法确定各指标权重和总排序权重,再经多因素(指标)、多目标(方案)模糊综合评判,得出采场宽度13m为最优结构参数。熵值计算结果表明,两帮位移是方案比较中的最重要指标,故开挖后应对采场两帮进行喷混支护。该措施对龙门山矿区L23矿体安全开采具有实用价值。

| Abstract: | The three schemes related to the option of different stope width (12m, 13m and 14m) of Longmenshan mining area L23 orebody has undergone an optimal selection by adopting the Fuzz Comprehensive Evaluation. By establishing the Analytic hierarchy process model of stope structural parameters and its membership matrix, combined with on-site investigation, we can define the technical and economic indicators. The further introduction of FLAC3D numerical simulation can output the six safety indicators such as the maximum principal stress, the shear stress, the roof displacement etc. Based on entropy method, the various index weights and total sort weights can be specified. The final conclusion that the 13m stope width is the optimal strucutral paramters can be drawn after the multiple-factors (indicators) |
