摘要
软岩井筒围岩变形易受多组相交剪切结构面、岩性、埋深等因数影响,在复杂地质作用下,非线性变形特征明显。宁夏宁东矿区地质环境十分脆弱,围岩性质复杂且多次出现此种现象。通过调查研究,在系统地分析软岩井筒围岩的局部化应力-变形机理的基础上,针对性的构建了"声-光-力"集成监测的三维可控加载物理模拟实验平台,形成了"人-机"结合的信息化识别立体模拟防控体系。为后期实验过程和结果分析提供基础支撑。
Deformation of soft rock shaft susceptible to multiple surfaces intersect shear structure, lithology, depth, and many other factors influence. Under the complex geological, nonlinear deformation of surrounding rock is obvious. Geological environment is fragile, nature of rock complicated and this phenomenon occurred many times in Ningxia Qingshuiying mine. After investigation and research, systematic analysis of the localized stress-deformation mechanism of soft rock surrounding, then targetedly constructed based on ＂sound-light-force＂ integration of three-dimensional controllable load monitoring physical simulation platform, forming a ＂staff-computer＂ combined information identifying prevention and control simulation system.
