Underground transportation is one of the most important factors for the operation of a mine which can be divided into two problems-transportation at working faces and main adits transportation.
High efficiency of transportation at working faces, the author concludes, can only be attained either by adopting a well suited method to the transports employed or its opposite.
Described below are the non-pillar overhand inclined long wall slicing method as an examplefor the former which uses scrapers as its main transports, and the short wall top slicing with Kappe method (accompanied with filling) as one for the latter which uses baby-conveyors as its main transports.
As regards main adits transportation, however, the descriptions are made with examples based upon the comparisons of:
(1) ordinary mine cars and dump cars.
(2) cages and skips, and
(3) belt conveyors and trolley cars.
