断裂(带)对采空塌陷及地裂缝地质灾害的影响——以山东新泰市河山子村为例

Fault zone's influence on subsidence and groud fissure in mining area——A case study at Heshan village of Xintai city,Shandong province

新泰市河山子村东部较大范围集中发生地面裂缝和房屋裂缝,裂缝点沿莲花山断层呈线状分布,所在地段远离采空区,基岩裸露,经调查分析,排除了岩溶塌陷、区域构造活动引发的可能,结合有关研究认为,断层带的存在使采空塌陷及地裂缝的影响范围扩大,就本区而言,较传统理论预测范围扩大了243m,相当于采空地面变形影响角减小为48°。

Xintai City river village East bigger range ground fissures and cracks occur centrally, crack point along Lotus Hill fault in linear distribution, location away from the goal, bare rock, after investigation and analysis, exclusion of the karst collapse, regional tectonic activity triggered by may, based on the thought, fault zone in goal and crack extent, with respect to this area, compared with the traditional theory to predict the range expansion of the 243m, equivalent to the mining ground deformation angle decreased to 48 degrees.
