| Abstract: | According to the similitude conditions that simulation of mechanical rock breaking must satisfy, through a lot of tests, this paper presents three kinds of analogous materials and the optimal proportion of their components. The relationship between the proportion of components and the mechanical index, strength features has been analyzed.The results show that as long as the proportion of components is proper, the analogous materials made up of gypsum, cement and sand can be used to simulate mechanical breaking of rocks (limestone, sandstone, shale,etc.) which are often met in mining engineering. |
