| Abstract: | Through the analogous material imitation study of the full-mechanized top coal caving.this thesis expounds when the top coal is in loose status,the back loss,the floor deposit loss and the mixing of rocks are generarcd. In order to increase the percentage of recovery a.id decrease the mixing of dis to gain better economical beneflts.the reasonable drawing ratio and drawing internal should be decided according to particular conditions and the destruction,clisplacement and falling of the top coal should be controlled efficiently. |
