摘要

The geological disasters of large area subsidence damage and the earth crack and house wall crack of the mined and groundwater dewatering in the Tieshikou Xiaojiang coal area of Xinfeng county have caused great impacts to thousands of villagers living there, and this problem also has influenced the stability of 105 state road and the Jingjiu railway line. This text analyzes the reasons and the developing trend of local area disasters including investigating the coal distributing, the mined history, the current situation and the disaster points location and happened time and scale etc. Finally, it's expected to find some regular patterns of those problems to help local villagers on disaster prevention and mitigation.%信丰县铁石口—小江煤矿区采空与岩溶因地下水疏干引发大面积的地面塌陷、地裂缝和房屋墙体裂缝等地质灾害问题,给当地数千村民的生产生活带来较大影响,并已影响到105国道与京九铁路路基的稳定性。本文试从煤矿分布、开采历史与现状、地质环境条件等方面,结合已发生的地质灾害点位置、时间和规模,论述区内地质灾害发生缘由以及发生发展趋势,以期找出一点规律,为当地防灾减灾提供一定的帮助。
