Abstract:
According to environmental and climatic characteristics, conditions of traffic transport and the present situation of mining in Shihu Gold Mine, several technologies such as three-stage slurring of dry tailings, continuous filling of unclassified tailings to form an artificial sill pillar, and continuous mining without pillars in panels were studied. As a result, the mine developed a technique with complete technology and equipment, of upward horizontal cut-and-fill stoping without pillars and in panel, using unclassified tailings and cement. By using this mining method, panel production capacity was up to 340 t/d, and ore dilution and loss were controlled within 1% respectively, which resulted in good economic, social and environmental benefits.
