A discussion on mining method of gently inclined multilayer vanadium orebody in Shanghengshan

The gently inclined multilayer vanadium orebody in ShangHengshan is regarded as typical hard-to-mine ore body.The complicated geological conditions make it difficult to choose mining method.The applicability,advantages and disadvantages of mining method about similar mines are analyzed and compared.Combined with the occurrence conditions in ShangHengshan vanadium mine,an mining scheme about the slice continuous mining respectively backfilling is proposed.A series of mining process are studied and the applicable effect is analyzed.The results showed that the method could enhance the stope ground pressure management.The ore loss rate and ore dilution rate are reduced.The work environment of mining stope are improved.The filling cost is reduced.This method can be applied with safety and high productivity and economical rationality,which doesn't only have a certain draw instructive for the gently inclined multilayer vanadium orebody in Shanghengshan,but also provide theoretical basis for the mining of similar mineral resources.
