| Abstract: |
| Wa Chang iron and copper mine is in Yongping country，it’s a small mining，the scale of production for 60000 t/a，pioneering way using flat adit development．Because fragmentized rock and firm sex difference，mining process easy happening safety accidents，such as roof falling、slabbing、landslide and so on，mining choose layered caving method．Through the production，found out the mining method’s various process parameters，those are suited for mining 1 # and 2 # ore body which belong to Wa Chang iron and copper mine．By analysis and summarize top slicing caving method completely suitable for mining 1 # and 2 # ore body which belong to Wa Chang iron and copper mine． |
