We are committed to sand and gravel crushing, industrial grinding, ore processing and green building materials, and provide intelligent solutions and mature supporting products.

Dec 21, 2018 Due to the limitation of the mining process in opencast mines, thin coal seams that are below the desired level of seam thickness for mining sometimes cannot be mined and the volume of that coal is considered as waste volume. Using GEOVIA Minex, this waste coal volume can be calculated and an estimation of the waste volume can be performed.
