摘要
利用所建立的模糊测度理论模型，分析港里矿区河下采矿引起的地表移动变形，并分别计算河下留设规则保安矿柱及哑铃状保安矿柱两种方案的地表变形。提出了可行的开采技术方案，所得结论可作为厚大倾斜金属矿体水下开采设计参考。
A mathematical model based on fuzzy nieasures theories was applied to thecalculation and analysis of the rock mass deformations and displacements due to mining under ariver at Gangli Mine,with an emphasis placed on the cases with regular pillars and dumbbell-likepillars. Based on the results from the fuzzy measures analysis,a valid underwater mining methodis nresented in this paper. The conclusions drawn provide a basis for designing the method ofunderwater sharply inclined thick orebodies.
