摘　　要：贵州省瓮安磷矿开采历史悠久,在北斗山磷矿区形成了大面积的地下采空区,因采空覆岩变形造成地面开裂变形,地质环境遭到了严重破坏,处于磷矿采空区及其覆岩影响范围内的贵州瓮安生物群化石核心保护区遭受威胁。因此,研究地下采空区注浆治理对化石群保护具有一定的意义。Phosphate mined has a long history in Weng’an of Guizhou province,and a large area of under⁃ground goaf is formed in Beidou Mountain phosphate ore area.Due to the ground crazation and deformation re⁃sulted from overburden deformation in goaf,as well as the destroyed geological environment,the key fossil re⁃serve of Guizhou Wengan biota,which is located in the area affected by the phosphate mine goaf and its overbur⁃den,is under threat.Consequently,it is very significant to study the slip casting treatment of underground goaf for the protection of Weng’an Biota Fossil.
