| Abstract: | Through the field measurement of driving test roads and sampling to determine the physical mechanical parameters of the floor strata and based on the simulation model test and numerical calculation, the floor strata stability of the contiguous seams in ascending mining face above the partial mined out area is analyzed,the destabilizing mechanism of the key floor strata is investigated,and the principle to determine the reasonable ascending mining method is put forward. |
