介绍了目前煤炭采空区地基稳定性评估与治理技术的研究现状。研究分析了承德兴隆矿业有限责任公司选煤厂的建(构)筑物和采空区概况，需评估采空区的存在对建构筑物的建设和使用的危险性，通过计算分析建筑物荷载影响深度与裂缝带发育高度之间关系，确定了需要治理的煤层采空区，并进行了采空区的治理设计，最后通过钻探等检测手段说明实际注浆效果较好，说明采空区评估与设计方案较好地指导了本次采空区注浆治理工程施工。

Research status on the stability evaluation and control technology of coal goaf foundation is introduced. General situation of buildings in coal dressing plant of Chengde Xinlong Mining Co. ,Ltd. and mined-out area are analyzed to evaluate the threatening of mined-out area existence to the construction and use of buildings. Through calculating the relationship be-tween the building load influence depth and the fracture zone height,the coal goaf that needs to be treated are determined,and the goaf governance design is proposed. Finally,the testing such as drilling and exploration indicated that the actual grouting effect is good,the assessment and design scheme of mined-out area can well provide guidance for the goaf grouting treatment and construction project.
