摘要
为弄清厚松散层薄基岩条件开采下不同影响因素对地表变形沉陷的影响规律,采用FLAC3D数值软件建立数值模型,模拟不同采宽、留宽、采深、松散层厚度、采高情况下水平位移和地表沉陷的影响规律。利用正交试验法研究确定不同影响因素对地表沉陷的影响程度,得出各影响因素对地表沉陷影响程度的主次排序为:留宽>松散层厚度>采宽>采高>采深。
In order to understand the influence rules of different influencing factors on surface deformation and subsidence under the mining conditions of thick loose bed and thin bedrock,FLAC3D numerical software was used to establish a numerical model to simulate the influence rules of horizontal displacement and surface subsidence under the conditions of different mining widths,retaining widths,mining depths,mining thicknesses and mining heights.Orthogonal test method was used to determine the influence degree of different factors on surface subsidence,and the order of the influence degree of each factor on surface subsidence was as follows:width reserved>thickness of loose layer>mining width>mining height>mining depth.
