| Abstract: | The subsidence characteristics of horizontally-sliced mechanized top-caving mining are different from those of either flat seam mining or steep-inclined middle-thick seam mining. Similar material model test was used to simulate the rock mass movement of steep-inclined super-thick coal seam of a coal mine. The results revealed the law of strata movement and ground deformation due to horizontally-sliced mechanized top-caving mining at a greater depth of steeply-inclined seam, which would provide a guide to real mining. |
| Keywords: | steep-inclined super-thick coal seam horizontal slice mechanized top-caving mining similar material model test law of strata and ground movement |
