济宁岱庄煤矿采空区注浆治理工程建设适宜性评价OA
Suitability Evaluation of Grouting Treatment Engineering Construction in Daizhuang Coal Mine Goaf Area in Ji'ning City
济宁市任城区五里屯建设项目位于岱庄煤矿注浆治理采空区的上方,本文根据该采空区注浆治理工程后地表变形监测数据,采用概率分析法计算充填后地表残余变形,残余下沉量2～16 mm,地表残余倾斜最大值为0.06 mm/m,残余水平移动最大值为4 mm,残余水平变形最大值为0.06 mm/m,确定采空区场地为稳定场地.按采空区对建筑工程的影响和拟建工程项目对采空区的影响两个方面评价工程建设的适宜性,为工程设计提供依据.
Wulitun Construction Project in Rencheng district in Ji'ning city is located above the grouting treatment goaf of Daizhuang coal mine.Based on monitoring data of surface deformation after grouting treatment in the goaf,probability analysis method is used to calculate the residual deformation of the filled surface.The residual subsidence is 2～16mm,the maximum residual inclination of the surface is 0.06mm/m,the maximum residual horizontal movement is 4mm,and the maximum residual horizontal deformation is 0.06mm/m.The goaf site is determined to be a stable site.The suitability of engineering construction has been evaluated from the impact of goaf on construction projects and the impact of pro-posed engineering projects on goaf areas.It will provide a basis for the design of this project.
