A Mine Bonus System Based on the Use of Performance Tables

THE orebodies of the Preston East Dome mine show a considerable variation in size,• shape, dip, and ground condition. They vary from small and large irregular masses being mined by shrinkage, cut-and-fill, and square set-and-fill mining methods to narrow veins being mined by open stoping. Standardization of mining operations has necessarily been difficult. This considerable variation in mining condition prompted the development of a bonus system which would give more equitable bonus payments throughout the mine than those obtained by the usually accepted methods of calculating mine bonus.
