These distance measures all have somewhat different properties.

#Surpac inverse distance squared block software#
6.6.1 software and inverse distance squared interpolation methods. This doesn't have all the nice properties of a distance derived from a norm, but it still might be suitable for your needs. three-dimensional silver domain solids using Geovia-Surpac Ver. The Inverse Distance estimation interpolates block values based on the values of the sample points closest to the block centroid. If the matrices are $\mathbf|$ is larger than some threshold number. Too long for a comment:Īs I said, there are many ways to measure the "distance" between two matrices. Fractal Models for Ore Reserve Estimation. Wang Qingfei, Jun Deng, Huan Liu, Liqiang Yang, Li Wan a, Ruizhong Zhang (2010). Then 32 + 12 10, so the distance is 110 blocks. It is the hypotenuse of a right triangle with leg lengths 1 and 3. Problems and opportunities for mineral deposit models, in Kirkham, R.V., Sinclair, W.D., Thorpe, R.I., and Duke, J.M., eds., Mineral deposit modeling: Geological Association of Canada Special Paper 40, p. Find the length of the segment connecting the points. Prefeasibilty Study of the Central Zone of the Ajabanoko Hill Iron Deposit. Preliminary Report on Ajabanoko Iron Ore Deposit. National Steel Raw Materials Exploration Agency (NSRMEA) (1994). The Inverse Square Law - Point sources of x- and gamma radiation follow the inverse square law, which states that the intensity of the radiation (I) decreases in proportion to the inverse of the distance from the source (d) squared: 2 1 d Iv This can be rewritten : 2 1 d I K where K is a constant of unknown value. Ore estimation result obtained from 30 drilling data was 76453.5 ton of Saprolite with density of 1.5 ton/m3 and COG (Cut Off Grade) Ni 1. V/O Tecchnoexport: On the Prospecting and Exploration of Itakpe Hill Iron Ore Deposit, Okene, Nigeria. detailed exploration data, processing by using Surpac 6.2 by Inverse Distance Weight: Squared Power estimation method. National Steel Development Authority (NSDA) (1976). Institute of Mining and Metallurgy, February. The input requirement is a SURPAC Source Co-ordinate file, in the Old System, containing the points to be transformed. Pre Cambrian Iron Ore Deposits and its Environment at Itakpe Ridge, Okene, Nigeria. The comparison between the above methods is carried out (if any method underestimates or overestimates) then the best method is decided accordingly. ordinary krigging inverse distance (power2 and 3) and nearest distance method. The Pacific Journal of Science and Technology. It aims at estimating the ores using different methods i.e. Rock Density- A Tool for Mineral Prospection: A Case Study of Ajabanoko Iron Ore Deposit, Okene SW Nigeria.
