Geological impact on the Mining Rate

 From geological point of view, mining rates will be most affected by the following

 

• Gravel volumes: the thicker the gravel volumes, the longer it takes for the holes to deplete. Thicker volumes also cause surging which prolongs presentation time.

• Gravel texture: the coarser the material, the lower the RPMs, then the longer it will take for the hole to deplete. Homogeneous geology improves mining rates

• Slab frequency:  the higher the frequency, the lower the RPMs, then the longer it will take for the hole to deplete.

• Lithology type: courser lithologies like large cobbles slows mining rate, while softer lithologies

• Hard or rough terrains such as sandstone, conglomerate s outcrops or cappings make it difficult for the tool to penetrate and thus slow the mining rate. It also affects slewing speed of the boom in terms of crawler mining systems.

• Steep slopes: require slow rotations of the tools and thus slow mining rates
