Abstract: Due to the actual project of Xiagao iron mine, there are some technical difficulties at ore recovery and security in the early stage of using the open-stoping method. Through multi-program comparison, it is determined that the caving method is adopted at later period of mining. But various techniques and skills for conversion and control exist during transition process. The paper puts forward the relevant measures in view of these difficulties, and has been better applied in mining engineering. Then, the technical difficulties for the ore recovery and mine safety are solved.
