摘　　要：本文将模糊致学中的模糊测度理论用于计算分析桃坪河磷矿河床矿柱开采而引起的地表移动变形问题。按模糊数学模型计算分析结果表明,桃坪河河床矿柱采用房柱法可以实现安全回采。河床矿柱总回采率可达50—60%。A mathematical theory of fuzzy measures has been applied for calculating and analyzing the ground movements and deformations due to mining of the pillars below a riverbed at Taopinghe Phosphorus Mine. The results showed that the pillars can be mined safely by the room-and-pillar method.
