本文就急倾斜矿体开采条件,结合云南省澜沧铅矿地下采矿方法,对人工混凝土顶板进行了变形地压和松散体压力分析计算。提出了人工混凝土顶板强度准则,并计算出结构参数,为采矿设计和地下工程安全提供了理论参考。
Based on the mining conditions of steeply inclined orebodies and the underground mining method of the Lancang Pb deposit in Yunnan Province, this paper analyzes the pressure and deformation of the artificial concrete roof under the conditions of deformation and pressure. The strength criterion of artificial concrete roof is put forward and the structural parameters are calculated, which provides a theoretical reference for mining design and underground engineering safety.
