results of a study on the technical and economic feasibility of mining the deep, thick, oil shale deposits of colorado's piceance creek basin are reported. the study was divided into two phases: first, a technical feasibility study of applicable mining methods, and second, an economic feasibility study, based on the designs developed in the first phase.
the study was divided into two phases: first, a technical feasibility study of applicable mining methods, and second, an economic feasibility study, based on the designs developed in the first phase. the first phase, completed in july, 1975, recommended four mining methods for the phase ii study. the four methods are: chamber and pillar mining
the updated feasibility study underground mining on the entrée/oyu tolgoi jv property is planned to be by large-scale panel caving, which is a variation of block caving. the size, geotechnical characteristics and depth of mineralization at the deposits on the entrée/oyu tolgoi jv property make block caving the best suited mining method
updated feasibility study proposes utilisation of the following exploration, design, development and mining approach: initial underground access via the nambonga decline, offering the following advantages: o earlier and quicker access to underground drill platforms in support of an extensive
