| Abstract: | Baigu mine paragraph is gently inclined thin- shaped Orebody to tilt,angle 7（°） - 45（°）, for mining stope 2-3 of mine lots after the apparent pressure. Orebody Stripping and caving roof delamination, through the improvement and reform of mining methods, strengthens the implementation of stope production management and slightly increases the recovery rate. The larger safe working environment has improved. |
