济南唐冶地块采空区勘查及稳定性评价

Exploration and Stability Evaluation of Goaf Area in Tangye District in Jinan

以济南市唐冶片区某开发地块为背景,唐冶片区铁矿资源较为丰富,但规模较小,主要为小型铁矿。勘查施工时发现地块内有铁矿开采历史,存在有废弃矿井。为圈定采空区范围及评价采空区场地稳定性,采用了资料收集、人员访谈、钻探、物探等多种手段进行了勘查,圈定了采空区范围、矿井具体位置及规模,进而评价采空区稳定性,提出治理建议,以减少对拟建建筑物的影响,最大限度减少或避免因采空区引发的环境问题,从而保护和改善矿山环境,保护人民生命和财产安全,为社会经济的可持续发展服务。

This paper presents a goaf area investigation and mitigation plan in Tangye District of Jinan City.The Tangye District has a rich deposition of iron ore resources with a high concentration in a very small area.An abandoned mine site was found in a local development district during the engineering investigation stage and was confirmed in the construction stage.The adopted data collection,local resident interview,a variety of means such as drilling,geophysical exploration for the mined-out area prospecting,delineated the scope of goaf area,location and size of mine,and evaluate stability of goaf area.Suggestions are proposed to the goaf area to minimize the impact on the proposed building,avoid the goaf caused by environmental problems.These suggestions can provide means and methods protect and improve the abandoned mine environment,protect people’s lives and property,maintain the sustainable development of social economy service,social stability and ecological environment stability.
