摘要
针对目前地下开采引起地表移动变形致使地表建筑物、构筑物及农田等遭受严重破坏的问题,以Knothe模型的函数为基础,探讨了时间影响系数的确定方法,建立了地下开采引起地表移动动态过程的计算模型,并采用阳泉二矿3201东工作面的实测岩移资料进行了验证。研究结果表明:该方法能够反映地表移动的动态特征,解释某些采动现象,对指导“三下”开采设计和选择地面建筑物保护措施具有较大的实用价值。
Directed at underground long-wall coal mining induced the ground subsidence resulting in potential damages to the surface structures, the prediction of progressive subsidence has been demonstrated, based on the Knothe time function, and the factor of proportionality, c, describing the influence of geological and mining conditions on the deformation process in time has been determined when there is no measured material in practice. The simulation of progressive subsidence for 3201E working face, Yangquan Coal Mine Two, indicates that this approach is effective and easy to apply for analysis in practice.
