The types of a gold mine in southern China are cataclasm medium -fine granite ,cataclastic rock , cryptoexplosion breccia and strong silicification dacite -porphyrite . In the early production of exploration and mining , according to the experience parameters and experience formula from similar mine , the open -air DT H drilling and blasting parameters were initially proposed in this golden mine . After detailed con‐trasting and carefully analyzing the blasting effect ,the DT H drilling and blasting parameters fit for the technical mining condition of this mine were confirmed , on the basis of the drilling and blasting parameters , the exploding operation can achieve the purpose of safe , efficient , economic and reasonable .
