| Abstract: | Xincheng Gold Mine is an altered type gold deposit. Influenced by geological structure, the stability of stope roof was poor and roof collapse often took place locally or in a greet area. For the satety of stope roof and raising technical economic index, a controlling blasting technique for ore caving of the stope was tested in order to conduct upward horizontal slicing and filling with cemented tailing. A desired result was obtained in the test. |
