Rationalization of Conveying Systems in Coal Mines

Abstract

A production technique in a coal mine consists of two techniques of getting coal in faces and conveying of it to the surface. The coal getting in faces is highly mechanized today, while the conveying is not rationalized sufficiently.
The author examined the conveying systems in a coal mine and suggested the following several rationalization methods: Using of a long belt conveyor instead of several short ones, that means reduction of number of conveyors in a system, increases the efficiency of conveying system; increasing of productivity in the coal face requires the installation of a pocket or bin between the gate road and the further conveying system in roadway. The necessary capacity of bin is determined by a method described in this paper.
