Abstract

Above the goaf, resource-based communities must construct civil buildings, industrial buildings, highways, bridges, and other transportation amenities. For the foundation treatment of the goaf, grouting technology is employed for the safety of the construction above the goaf. The selection of injection paste material and the investigation of grouting treatment technology of a high confined water rich gob region were thoroughly investigated based on the treatment project of a high confined water rich gob area in Zhangqiu District, Jinan City, Shandong Province. First and foremost, thoroughly grasp and analyze the project’s geological circumstances and coal mining. Second, it is comprehensively determined that the goaf management adopts the partition management mode, and adopts the grouting and filling management scheme combining vertical drilling and directional drilling, and conducts experimental research while grouting construction, in order to improve the dynamic mode of grouting scheme at any time. Finally, the injecting paste material was tested to determine the best slurry ratio, and the grouting technology of “curtain”, “Divide”, “use”, and “Out” was tested, as well as the grouting effect, which solved the practical problems of the grouting treatment project.
