Suitability Evaluation of Grouting Treatment Engineering Construction in Daizhuang Coal Mine Goaf Area in Ji'ning City
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.
