Evaluation of a slate extraction bank

摘要: AbstractTo mechanize extraction from a slate quarry it is important, first, to assess the quality of both bed and estimate potential economic yield, so as optimize outcome cuts made in bank. A methodology described that can be used support by those charge extraction. The first phase consists definition geotechnical parameters affect bank aesthetic quality. second involves application multivariate techniques with view establishing recovery factor for resource index block slate, variation intervals established rock faces samples analysed. third use geostatistical extrapolate values obtained interior This enables entire deposit assessed permits mechanized cutting tasks planned i...
