石膏矿区采空地面塌陷易发性分区与监测预警研究

Research on susceptibility zones and monitoring and early warning of ground collapse in gypsum mining area

邳州市邳北石膏矿区采空地面塌陷日益严重,为防治地质灾害,市政府于2016年进行了石膏矿区采空地面塌陷专项地质灾害防治规划。通过分析矿区已有资料、分析已发塌陷点和现场调查,阐述了采空区地面塌陷的特点与危害,并采用模糊综合评判方法对地面塌陷的易发性进行了分区。根据分区结果,结合人员密集程度,提出了区域采空区综合治理和地面塌陷地质灾害防治监测预警的措施和方法,为地质灾害防治工作提供依据。

With the increasingly serious problem of ground collapse in gypsum mining area of North Pizhou and in order to carry out the geo-disaster control work,the government made the plan of prevention and management for ground collapse in gypsum mining area in 2016. Through analysis of available data,collapse areas( those found)and field survey in gypsum mining area of North Pizhou,the authors explained the characteristics and hazards of ground collapse in gypsum mine goaf. In addition,they made the susceptibility evaluation of ground collapse using the fuzzy comprehensive evaluation method. Based on the results and population density,the authors put forward the method and measures for comprehensive treatment of the mine goaf and monitoring and early warning of ground collapse. This paper would provide some scientific reference for the geo-disaster control work of government and other similar geological areas.
