Industry:Mining
A statistical measure (where zero is impossibility and one is certainty) of the likelihood of occurrence of an event.
Industry:Mining
A statistical measure of the correlation between two variables. In geostatistics, covariance is usually treated as the simple inverse of the variogram, computed as the overall sample variance minus the variogram value. These covariance values, rather than variogram values, are actually used in kriging matrix equations for greater computational efficiency.
Industry:Mining
A statistical term referring to saleable coal, less colliery consumption and coal supplied to employees.
Industry:Mining
A steam engine used in excavating and for digging and raising stones and gravel for ballast.
Industry:Mining
A steam hammer, having the head attached to the piston rod, and operated by the direct force of the steam.
