摘要: 针对吴集铁矿矿体赋存特点,主要从应力变化方面分析了采空区失稳冒落的危害、主要原因和影响因素,并提出了高浓度全尾砂胶结充填的采空区治理措施,充填料浆浓度及尾砂利用率高,为矿山治理采空区和充分利用矿山废料提供了依据。

关键词: 采空区, 稳定性, 高浓度全尾砂胶结充填

Abstract: In view of the occurrence features of Wuji iron ore, the endangers, main reasons and influencing factors of goaf caving from the stress change have been analyzed.A handling method with high concentration whole-tailing cemented filling was proposed with characteristics of high filling slurry concentration and high tailing utilization, thus providing a theoretical basis for handling the golf and making full use of mine wastes. 

Key words: Golf, Stability, High concentration whole-ailing cemented filling method
