摘要
综合旺格维利采煤法和短壁式充填采煤法的特点提出了旺格维利充填采煤法。以王台铺煤矿XV23(09)工作面建筑物下开采为工程地质背景,采用实验室物理相似模拟及现场工业性试验的方法研究旺采充填采煤条件下的覆岩和地表变形特征。相似模拟结果表明,地表最大变形量的相似模拟预计值和现场实测数值基本吻合,两者所得各地表变形指标的最大值均小于国家规定的建筑物Ⅰ级损坏等级指标,XV23(09)工作面对应地表建筑物没有损坏。
The Wongewilli filling coal mining method is proposed by integrating the characteristics of the Wongewilli coal mining method and the filling coal mining method.Taking the mining of XV23(09)working face which is under buildings in Wangtaipu coal mine as the engineering geological background,the overburden and surface deformation characteristics under the condition of Wongewilli filling coal mining were studied by laboratory physical similarity simulation and on-site industrial test.Similar simulation results show that the maximum value of each surface deformation index is less than state-designated class I damage rating indicator,the buildings above the XV23(09)working face were not damaged.
