Continuous mining

摘要

Docmnt7-1/09/2016 A method useful in the continuous ore extraction in underground works intended for the permanent production of extraction from draw points or trenches, comprising the 5 construction of reduced size drifts wherein through the center defined by a group of drifts crossed a drift which is intended for ore haulage, such drift crosses successively all drift groups defined at the exploitation face, such extraction points are arranged to form a regular layout at certain distances which are compatible with an interactive gravitational flow; once such drifts, trenches, and haulage drifts are constructed the pre-conditioning, 10 caving and extraction stages are carried out.
