Overlying Strata Deformation Law of High Concentration Cemented Filling Mining in Coal Mine

In order to study the overlying strata deformation law of high concentration cemented filling mining in coal mine, we take 10203 filling mining face of No.10 mining area in Xinyang Mine as study background, theoretical analysis, numerical simulation and analogy simulation were applied to study overlying strata deformation characteristics of filling mining working face. The results showed that the main key strata fracture did not occur, with only a tiny deformation; strata deformation gave priority to vertical bending of a whole movement, fracture and caving did not occur without obvious caving zone; compared with vertical direction, the horizontal direction movement deformation is small, can be ignored basically. According to the conclusion, the research emphasis of filling mining surface movement deformation put on the strata movement deformation in vertical direction and surface subsidence is reasonable.
