【Abstract】 According to the geology and the mining conditions in Xincheng gold mine,the techno-economic comparison among three alternative mining methods was made. At last,the mechanized panel upward-slicing stoping with fill was selected.The test result showed that this mining method was higlily efficient,economical and safe, and the expected techno-economic indexes were obtained.In a word,the mechanized panel upward-slicing stoping with fill is of widespread use value to the similar orebody mining.更多还原
