摘要
为了评价矿山开采对地表建(构)筑物的影响,基于地勘单位提供的钻孔数据,借助成熟的三维数值分析软件Midas-GTS建立丁家庄铁矿的三维地质模型。更真实地反映矿区的地质构造,分析得出矿山开采造成的地表村庄沉降位移。地表村庄的最大水平变形为2.2×10^(-3)mm/m,最大倾斜为0.60×10^(-3)mm/m,均小于Ⅲ级建筑物的变形允许值。
According to the drilling data provided by geological survey units,a three-dimensional geological model of the Dingjiazhuang iron mine is established to evaluate the influence of mining operations on surface structures with the mature three-dimensional numerical analysis software Midas-GTS,which is more realistic to reflect the geological structure of the mining area.The data of surface village subsi-dence that results from mining operation were obtained.The maximum borizontal deformation is 2.2 × 10-3 mm/m and the maximum in clination is 0.60 × 10-3 mm/m,both of which are within the range of acceptable deformation values for Class Ⅲ structures.
