| Abstract: |
| This paper discusses main technological parameters such as cut mode,charging structure,charging density,ignition order,number of holes and total charge for drifting in stratified rocks in Lecang Lead Zinc Mine By atopting the optimal parameters and integrated management,the mine has decreased the cost of roadway excavation and increased the utilization factor of blastholes,achieving a significant benefit |
