Abstract:

Mining Method of mill-run tailing filling is a relatively mature technology.The key of the method is how to apply the technology.At present,the pillarless caving  is used in Xiadian Gold which is applicable for stability and heavy orebody,but not for the corner orebody or broken orebody.In order to solve the problem of high ore loss,dilution rate and low security of the corner or broken orebody mining,to mine more ore efficiently and safely,to take advantage of limited mineral resources and meet a substantial increase in the processing plant.Xiadian Gold selected  multiple stope,by practicing,analysising carefully and adjusting the parameters,obtained multiple sets of valid and reliable data, and ultimately developed a simple,effective and practical mining method of horizontal stratified entrance-filling of tailing, acquired a corking economy benefit.Mining is a subject with good practical character.Every mining method may supply each other and learn from others's strong points to offset one's weakness.Being a supplementation to other mining methods,the mining method is introduced in this paper with a good value of application.

Key words: Tailing filling, Corner broken orebody, Application, Xiadian gold deposit
