根据某矿厚松散层、大采深、长工作面、机械化采煤条件下2个初采和1个重复开采工作面观测站实测资料,通过移动变形计算和规律分析,获取了基于概率积分法的地表移动变形预计参数,从地表移动持续时间、下沉状态、地表移动盆地特征、概率积分法参数等方面总结了重复开采与初采时地表移动变形规律的差异,为类似地质采矿条件下的重复开采地表移动变形规律分析提供参考。
According to the measured data of two primary mining and one repeated mining face observation station under the conditions of thick layer, large mining depth, long working face and mechanized coal mining in a certain mine, through the calculation of displacement and regularity of deformation, , The differences of surface movement and deformation law between repeated mining and initial mining are summarized in terms of the duration of surface movement, the state of subsidence, the characteristics of surface moving basin and the parameters of probability integral method. Provide reference for the analysis of the law of surface deformation during repeated mining.
