Abstract: The paper uses the large-diameter deep hole side caving and subsequent filling method to testmining methods based on the mining techniques and conditions in a certain area of a metal mine. Accord-ing to the stability and cavern support of the roof cutting and side wall after the mining method test, thestability of the roof and side wall after the mining blasting in the stope is analyzed in order to study thejoint structure in the stope and the ore control fault in the upper and lower walls for subsequent filling ofthe empty stope. The influence of filling method can provide basis for selecting mining method and designing structural parameters of mining method in deep mine.

Key words: stope stability, cavern support of the roof cutting, large diameter and deep hole side cavingand subsequent filling method, lateral caving, subsequent filling method
