摘　　要：为解决榆林市榆阳区三台界煤矿采空区悬顶灾害问题,采用现场调查和理论分析提出了房柱式和条带式采煤工艺悬顶灾害评价方法,然后基于该评价方法对三台界煤矿采空区悬顶进行危险性区域划分,最后根据危险性区域划分情况开展针对性的监测和充填防治措施,保障了矿井安全生产。研究成果可为类似采煤工艺矿井大面积悬顶灾害防治提供技术参考。In order to solve the unsupported roof disasterin goaf of Santajie coal mine in Yuyang district,Yulin city,the evaluation method of unsupported roof in goaf of room-pillar and strip coal mining technology was proposed by using field investigation and theoretical analysis.Then the dangerous area of unsupported roof in Santaijie coal mine was divided based on the evaluation method.Finally,according to the classification of dangerous areas,targeted monitoring and filling prevention measures were carried out to ensure the safety of mine production.The research results can provide technical reference for prevention and control of large unsupported roof disaster in similar mining process mines.
