  • Selective Mining Article about Selective Mining by The

    selective mining[si′lek·tiv ′mīn·iŋ] (mining engineering) A method of mining whereby ore of unwarranted high value is mined in such manner as to make the low-grade ore left in the mine incapable of future profitable extraction; in other words, the best ore is selected in order to make good mill returns, leaving the low-grade ore in the mine

  • Definition of selective mining Mindat.org

    In coal mining, selective methods may be dictated by market demands and prices. It may be desirable to work the different quality coal seams in such proportions as to obtain a uniform and salable blend over a period of years. In metal mining, the stopes may be restricted in both length and width and thus produce a much higher grade of ore. It is not always practicable to resort to selective

    mining means average grades can be estimated for a block size of about 25 x 25 x 5m (bench height) to provide in-situ global estimates. However, if the ultimate selective mining unit is . 5 x 5 x 5m blocks, then cut-offs should not be applied to the 25 x 25 x 5m in-situ estimates without taking into account the effect of change of support to that of the selective mining units. Similarly, cut

  • Definition of Operational Mining Unit (OMU) Size

  • What is the abbreviation SMU in connection with mining

    21/09/2007· The selective mining unit (SMU) reflects mining selectivity. When Uniform Conditioning was carried out, the proportion of ore and metal tonnes above a cut-off were computed by determining how many SMUs within a panel were above that cut-off. In this study, it was established that a 6.25mE x 25mN x 10mRL panel could be reliably estimated from the given drilling grid, and that a SMU of

    Mining Applications. Geostatistics has long been used in mining applications for grade control and the assessment of recoverable reserves. Grade control is important because the decisions are final. Long term and medium term estimates are interim as the decision of what is ore and waste could always change; however, the decisions made during grade control are irrevocable. Early in development
