Study and reasonable choice of productive probing grid and probing method at Hetai Gold Mine

Through analysis contrast and study on different probing grids in this, it is concluded that the productive probing grid of 20m X 20m fills the needs of production and has economic feasibility at Hetai Gold Mine. It also offered the suggestion on the reasonable choice of the probing method in the future. As the change of mining depth and mining method, the probing method such as run probing, drilling probing or the combination of them must be selected reasonably. It is worthy to be used as reference in similar mines.
