为了保护新三矿地表受开采影响区域内的建筑物,需对新三矿南翼采区地表赵庄村进行保安煤柱设计。设计选择使用垂线法进行保安煤柱留设,通过对复杂地质构造区域上的建筑物保安煤柱设计方法的探讨和分析,精准地留设出了赵庄村保安煤柱线。经实测,赵庄村地表水平变形、倾斜与曲率均在Ⅰ级损坏等级范围内,有效地保护了赵庄村地表建筑物。

In order to protect the buildings in the area affected by mining on the surface of Xinsan Mine, it is necessary to design the security coal pillar on the surface of Zhaozhuang Village in the south wing mining area of Xinsan Mine. The vertical line method is designed and chosen for the retention of the security coal pillar. Through the discussion and analysis of the design method of the security coal pillar for buildings in complex geological structure areas, the Zhaozhuang Village security coal pillar line is accurately reserved. After actual measurement, the horizontal deformation, inclination, and curvature of the surface in Zhaozhuang Village are all within the range of Level I damage level, effectively protecting the surface buildings of Zhaozhuang Village.
