Abstract
The present invention refers to a set of methods and procedures that may be combined in order to greatly increase the speed of development of an access ramp in a underground hard-rock mine. More particularly, the present invention was designed to target all the bottle-necks comprised by the access operation of a hard-rock mine that employs a RAIL-VEYOR machine. The invention also comprises of an ore production line which consists in the sequential arrangement of a series of mining equipment between the work face and the entrance of a hard-rock mine. The invention also comprises a Hard Rock Mining Access Plan for a hard-rock mine which encompasses two parallel ramps interconnected by cross-cut passageways. Further, invention also comprises a Ground Support Installation method configured to shorten the time required for the installation of ground support inside of a hard-rock mine.
