Quarrying Opencast and Alluvial Mining John

Quarrying and all other branches of surface mining rather than diminishing in importance have become of more and more consequence economically, industrially and particularly with the depletion of high-grade deep-mined mineral reserves. Low-grade minerals require low cost extraction and this in many cases necessitates very expensive mechanized equipment with the cost of individual units running

The Selection and Rational Evaluation of Surface

Abstract. The most important part of surface mining design is to select the rational technology system. On the basis of the classification and according to various applicable conditions, we should determine a corresponding mining technology system for all sorts of opencast coalfield in order to give guidances on the mining design and to provide theoretical bases on the selection of mining

Ppt On Opencast Coal Mining Vollendam

Mining Methods Coal is mined by two main methods surface or opencast mining and underground mining.. The choice of method is largely determined by the geology of the coal deposit; the majority of the world's coal reserves are recoverable by underground mining. The method used is determined by the depth of coal deposit and the overburden over it.
