Optimization of Sampling Method for Rotary Drilling
Combined with the actual situation of fine mining and ore blending in Heigou open pit stope,the sampling method in the process of ore quality measurement is optimized and improved,and the chart data of ore body position,ore body shape,ore quantity and ore grade are obtained.It provides an important basis for guiding the production of fine mining and ore blending.Through the rock(ore)longitudinal cutting sampling survey,the loss and dilution of blind small ore body are reduced,and the resource utilization rate is improved.
