摘　　要：为研究浅埋厚煤层高强度开采地表移动规律,结合哈拉沟矿地质采矿条件,在22407工作面上方布设合理的地表移动观测站,进行地表移动和变形监测,获得较为完善的地表移动和变形资料。通过分析地表走向和倾向观测线的静、动态移动变形曲线,获得地表移动变形规律、相关角量参数及概率积分法预计参数。结果表明,在浅埋厚煤层高强度开采条件下,地表下沉比较剧烈,地表最大下沉速度达到696 mm/d,移动变形比较集中,能够快速形成下沉盆地,地表移动在很短的时间内达到稳定状态。研究成果可以为类似矿区设计"三下"采煤及合理留设各类保护煤柱、地表沉陷预计提供参考。In order to study the surface movement characteristics of the high intensity mining under shallow depth thick seam, it was combined with geological and mining conditions of Halagou mine, the reasonable surface movement observation stations are built above 22407 working face, and whole surface movement data was obtained by surface movement and deformation monitoring. The characteristics of surface movement and deformation,angle parameters, as well as probability integral prediction parameters were obtained by analyzing the static and dynamic surface movement and deformation curves of the strike and dip observation lines. The results are that, the total subsidence velocity reaches to 696 mm/d, the surface movement and deformation is more concentrated, and the subsidence basement is formed rapidly, the surface movement reaches to steady state quickly, under the conditions of the high intensity mining of shallow depth thick seam. All the results can provid escientific basis for designing of the u three-undercoal mining, setting all kinds of protective coal pillars and pre-warning of surface subsidence.
