摘　　要：为研究煤炭深部开采时长壁开采与条带开采工艺条件下地表沉陷规律的差异性,以某矿千米采深的630采区为研究对象,基于实测数据求取了地表移动角量参数、下沉速度和概率积分法参数。研究结果表明,长壁开采地表危险影响范围和地表移动变形剧烈程度明显超过条带开采,随着开采深度的增加,下沉系数和主要影响正切角逐步增大,开采影响程度呈现越来越明显的趋势。To investigate the differences between surface subsidence laws in longwall mining and strip mining technologies for deep coal mining,taking the No.630 mining area with a depth of one kilometer in a certain mine as the research object,the parameters of surface movement angle,subsidence speed,and probability integration method were obtained based on measured data.The research results indicate that the range of surface hazards and the degree of surface movement and deformation caused by longwall mining are significantly greater than those caused by strip mining.As the mining degree increases,the subsidence coefficient and the tangent angle of the main impact gradually increase,and the degree of mining impact shows an increasingly obvious trend.
