With twenty years mining history, Fenghuangshan Copper Mine encountered serious problems such as high are loss and dilution, poor safety when cut-and-fill with post pillar mining method was being used. To solve the problems, large diameter longhole mining was experimented. Spherical cartridges of ordinary ammonium nitrate explosives instead of high power explosives were used for VCR blasting by paralled inclined large diameter longholes, VCR method was successfully used for slot cutting combined with longhole stoping blasting. Experiments and results were presented in the paper.
