摘要
为研究采空塌陷区稳定性及塌陷引起的地质灾害风险,本文以徐州张双楼矿区为例,首先通过遥感技术和实地调查对矿区采煤沉陷区的分布特点进行分析;其次,基于GIS技术,选用层次分析-信息量法评估矿区的地质灾害危险性,得到危险性评价分区图,并与易损性评价相结合,获取地面塌陷风险分区结果图;最后,基于徐州张双楼矿区土地资源损毁现状和塌陷区易损性、风险性分区,根据矿区实际情况对塌陷区进行土地复垦治理。
In order to study the stability of the goaf subsidence area and the geological disaster risk caused by the subsidence, this paper takes a mining area in Xuzhou as an example. First, the distribution characteristics of the coal mining subsidence area in the mining area are analyzed through remote sensing technology and field investigation;Analytic Hierarchy Process-Information Method evaluates the risk of geological hazards in the mining area, and obtains the risk assessment zoning map, which is combined with the vulnerability evaluation to obtain the result map of ground collapse risk zoning. Finally, based on the current situation of land resource damage in Zhangshuanglou mining area in Xuzhou According to the vulnerability and risk zoning of the subsidence area, the land reclamation and management of the subsidence area shall be carried out according to the actual situation of the mining area.
