根据新疆六道湾煤矿西翼采空区地表变形的实地调查资料,总结了地表裂变形的特征和发育规律。采用数值模拟分析方法研究了急倾斜煤层开采后地面沉陷规律,其结论对分析地表变形的形成机理提供了理论上的保障和依据。
According to the field survey data of the surface deformation of the goaf in the west of Liuduowan coal mine, the characteristics and development rules of the surface fission are summarized. The law of ground subsidence after the mining of steep coal seam is studied by numerical simulation method. The conclusion provides a theoretical guarantee and basis for analyzing the formation mechanism of surface deformation.
