摘要
文对模拟煤体或软岩的相似材料配比进行了试验研究,分析了砂胶比、水固比等因素对相似材料模型物理力学性能的影响规律,并确定了不同抗压强度的相似材料的配比方案。
The ratio of similar materials for simulating coal and soft rock was studied in this paper. And the law effect of related factors, sand-binder ratio and water-solid ratio etc. to mechanical properties of similar materials have been analyzed, and the mix proportions for similar materials with different compressive strength have been determined.
