摘要
梁洼煤矿西部的军营沟矿井开采时,在采用63的移动角图定的影响范围之外,部分建筑物仍旧出现了裂缝、本文在实地调查的基础上,根据房屋的结构特征和房屋损害现象,指出了竹茂村房屋裂缝的原因,同时求得了梁洼煤矿军营沟矿井的移动角和边界角值。
While recovering the coal of Junyinggou mine situated at the west of Liangwa colliery, fractures are also leaded on many houses out of influence range deter mined on the angle of displacement 63°. Based on investigation in site, this paper gives the causes of fraekture on buildings according to the characteristic of structure and damage of the builings.
