Choice of Method - Welcome to the Narrow-Vein Mining Project
During the visit, the mine was putting more emphasis on the narrow-vein mining method The method used at David Bell mine is the Alimak mining method However, for narrower veins, the longitudinal retreat mining is used The selection criteria for the Alimak mining method are numerous The main one is based on economic and the other ones are:
Hard rock room and pillar mines are generally quite large Rooms can be stoped out to 12 by 15 m in some cases, which requires significant air flow rate to meet minimum velocity requirement The large air flow rate has effects on other structures such as stopping and ventilation doors, which must be built to withstand the enormous air pressure
haulage, considering the entire mine , Shaft Location a) Dipping Veins Most mines favour vertical shafts because there are now more sophisticated systems to dig them and hositing speeds are greater The choice of location of a vertical shaft in a narrow vein is shown above Position 1 is favoured because in a dipping vein, the hanging wall is .
