| Resumen |
Examples of crump prevention by forcing water into holes in unmined coal are presented. An attempt was made to determine the extent of crack propagation and establish a criterion of destruction of coal bed structure by forcing water. Destruction of coal bed cohesion limits crump hazard. A model is presented for selecting hydraulic parameters of liquid spreading in the coal bed during water injection. Observations are presented that can be used in practice to limit crump and tremor hazard. |
