根据模拟岩石机械破碎应满足的相似条件,通过大量的试验,本文研究了三种不同原料配成的相似材料,以及相似材料的配比和其力学指标、强度特征等的关系。研究结果表明:选用石膏、水泥和砂配制相似材料,只要配比合适,可以模拟采矿工程中常见岩石(石灰岩、砂岩、页岩等)的机械破碎。 According to the similar conditions to be met by mechanical rock crushing, a large number of experiments were conducted to study the similar materials compounded by three different kinds of raw materials, the ratio of similar materials, the mechanical properties, the strength characteristics and so on. The results show that the selection of gypsum, cement and sand preparation of similar materials, as long as the ratio of the right, you can simulate mining rock common engineering (limestone, sandstone, shale, etc.) mechanical crushing.
