| Abstract: | Based on the similar material simulation and prectical experiment in situ, the movement charactedistic of overburden strata of longwall sublevel caving method has been studied in the paper. The roof beds structure and their movement features which have obvious effect on underground pressure manifestation are presented. A simple and useful method for calculating the static roof pressure has also been disscussed. |
