| titleOfInvention | Goaf caving rock particle size evolution migration rule simulation method |
| abstract | The invention discloses a goaf caving rock particle size evolution migration rule simulation method, which comprises the following steps: rock stratum sampling: and carrying out on-site drilling sampling on roof rock strata of different layers above the coal bed, and carrying out statistical analysis on the distribution state of the protogenic rock blocks in the rock by using related equipment to obtain the grain size distribution and the space distribution rule of the caving rock of different layers. The method is beneficial to realizing safe and efficient production and environmental ecological protection of the coal mine, and meanwhile solves the problem that as the overlying strata gradually fall, the stress of rocks in a collapse zone is increased, the collapsed rocks are slowly compressed, so that the particle size of the broken rocks is correspondingly changed, and the surface subsidence is predicted. The method for simulating the migration rule of the rock particle size evolution is simple and efficient, not only is the feasibility and the safety high, but also the precision is accurate, and the test rule can be better determined through layered demonstration experiments and repeated calculation, so that the method is worthy of popularization. |
