A Study on the Selection of Mining Methods for a Rapidly Dipping Thin Gold Vein
In this paper,the mining methods of shallow hole retention,upward horizontal layered filling and sectional caving without bottom pillar are used as the primary selection methods,and the AHP analytic hierarchy process is introduced to analyze the weights of six indicators,including mining cost,recovery rate,mining-cut ratio,dilution rate,annual output and ventilation conditions,and then normalize the weights of each index to obtain the comprehensive score of each mining method.By comparing the indexes and their comprehensive scores,it is found that the upward horizontal layered filling mining method has the best index.After industrial experiments,it was found that the gold ore backfill mining had reached the expected output target and had good applicability in various technical and economic aspects after using the upward horizontal layered fill mining method.
