采矿工程相似材料及模型试验研究

根据某矿工程地质条件,选用河砂、石灰和石膏为相似材料,进行了相似材料力学性质配比实验和平面物理模型试验。研究结果表明：所用相似材料能够反映原型材料力学性质;平面模型试验再现了综放工作面覆岩运动和破坏的情景,覆岩冒落过程与工程实际相符较好。

Analysis on mining engineering similar materials and model test

According to the geological conditions of a mine engineering,selected the river sand,lime and gypsum as similar materials,made similar materials mechanical properties proportioning test and plane physical model test.The results showed that: the used similar materials could reflect the prototype mechanical properties,the plane model test reproduction of fully mechanized caving face overlying strata movement and failure scenarios,cover rock caving process and engineering practice accorded very good.
