摘要:
复杂环境与多场耦合作用下,采空区煤岩体非对称变形诱致局部化失稳极易演化为动力灾害。以乌鲁木齐矿区急倾斜煤层综放开采为背景,构建了大型立体地球物理模拟装置与“声-光-电”物理力学指标信息测试系统,完成了动态加载条件下顶煤与覆岩损伤与演化的AE规律、内部损伤变形、表面位移变化特征、支架工作特性等分析,为急倾斜厚煤层综放开采与灾害控制奠定科学基础
Abstract:
Under the complex environment and multi-field coupling effect, un-symmetric deformation of the mined-out-area would cause the localized destabilization so as to induce disasters. The aims of the top-coal-mining to steep seam at Wulumuqi coal region, a large-scale and three-dimensional geophysical simulation assembly were built with hybrid test system of the acoustics-optics-electricity indicators. The regularity of AE in the top coal and overburden rock damage and evolution were evaluated and the internal damage deformation, various characteristics in surface displacement and support characteristics are analyzed under the conditions of dynamic loading. Those provide the scientific foundation for the steep and thick coal seam caving and disaster control.
