Mining methods should improvise and stereotyped thinking of mining methods should be overcome in the first place.In light of local steepening and thickening of ore sections in Zimudang Gold Mine,the paper carried out experimental research on medium-long hole caving along the inclination and cutting mining method.The structural pa-rameters and the stoping of tested ore blocks are introduced in full.Its application reached satisfactory technical and e-conomic results.
