中文摘要: 根据红岭铅锌矿开采技术条件,用HyperMesh软件建立符合矿体复杂特征的三维有限元数值模型,对红岭铅锌矿各中段开挖后的岩层移动规律进行了深入分析,获得了红岭铅锌矿岩层移动范围。结果表明:岩层移动破坏范围的模拟结果与现场实测值较为吻合,通过数值模拟位移分析,确定了矿体上盘岩层移动角59.2°,下盘岩层移动角63.8°,端部岩层移动角68.9°,圈定了红岭铅锌矿矿床开采地表移动范围,为红岭铅锌矿安全高效开采提供了理论依据。
Abstract:According to the technical conditions of Hongling lead-zinc mine, the three-dimensional finite element numerical model corresponding to the complex characteristics of the ore body was established by HyperMesh software. The rock movement law after excavation of the stage of Hongling lead-zinc mine was explored, and the range of movement of ore and rock in Hongling lead-zinc mine was obtained. Results indicated that:the simulation results of the rock stratum movement and failure range were in good agreement with the field measured values. Through the numerical simulation displacement analysis, it was determined that the movement angle of the rock mass on the upper part of the ore body was59.2°, 63.8° on the lower part of the ore body, and the movement angle of the end rock layer was 68.9°, defining the surface movement range of the Hongling lead-zinc mine. It can provide a theoretical basis for safe and efficient mining in Hongling lead-zinc mine.
