Discussion on the declination mechanism and the control technology of stope roof

During the process of underground mining,the stabilization of stope roof is the basement of normal and productive mining. But the declination mechanisms are complex and be many influence factors. It results in serious jeopardize from being lack of strict control measures. According to the mechanisms, the article summarizes six measures, expatiating the principles and advantage-disadvantage. It will provide important theoretic basis for the management of stope roof in mine.
