摘　　要：煤矸石作为建筑地基材料回填是矿业固体废料有效利用的途径。但由于煤矸石本身存在的特殊物理力学特点,使用煤矸石作为地基时,上部建筑物会随着矿区采动影响产生持续性或非持续性形变,这种形变会导致建筑物地基发生沉降,建筑物结构产生缝隙,出现开裂甚至倒塌的情况。为了尽量避免由于不均匀变形对矿区正常生产造成安全隐患,需要对煤矸石地基上层建筑物变形破坏机理进行研究,并结合工程实例采用注浆加固技术对地基进行有效处理。希望所述内容能够为今后此类工程提供借鉴和参考。The backfilling of coal gangue as building foundation material is an effective way to utilize mining solid waste. However,due to the special physical and mechanical characteristics of coal gangue itself, when coal gangue is used as the foundation, the upper building will produce sustained or non-sustained deformation along with the mining influence, which will lead to the settlement of the building foundation, cracks and even collapse of the building structure. In order to avoid the safety hazards caused by uneven deformation to the normal production of the mining area as much as possible, it is necessary to study the deformation and destruction mechanism of the superstructure of the coal gangue foundation, and use grouting reinforcement technology to effectively treat the foundation in combination with the engineering example. It is hoped that the mentioned content can provide reference for such projects in the future.
