济南市禹瀚产业用地采空区特征及稳定性评价

Characteristics and stability evaluation of goaf of Yuhan industrial land in Jinan City

在充分收集地质环境背景资料的基础上,开展济南市埠村煤矿采空区特征调查和稳定性评价。结果表明:瞬变电磁和大地电磁测深剖面识别出2个采空区异常带,为3煤采空区引起;推断出F_(1)、F_(2)、F_(3)断裂;查清了采空区的竖向特征,埋深东深西浅,且已充水;场地和地基稳定性较好,适宜和比较适宜禹瀚产业用地高层和多层的建设要求。

On the basis of fully collecting the geological environment background data,the characteristics investigation and stability evaluation of goaf in Bucun coal mine,Jinan City,were carried out.The results showed that the transient electromagnetic and magnetotelluric sounding profiles identify two abnormal zones in the goaf,which were caused by the goaf of 3 coal seam.F_(1),F_(2)and F_(3)faults were inferred.The vertical characteristics of the goaf were found out.The buried depth is deep in the east and shallow in the west,filled with water.The site and foundation have good stability,which was suitable for the construction requirements of high-rise and multi-story buildings of Yuhan industrial land.
