Fire protection systems on conveyor transport in mines

Authors: Shaportov A V

A belt conveyor is a common means of ore and gangue haulage in underground mines. The present-day conveyor networks in mines may be several kilometers long. At the same time, a conveyor is a sophisticated engineering device. It requires permanent attendance, while improper maintenance may cause risk of fire. The fire detection and prevention activities use various systems of measuring and monitoring concentrations of combustible and toxic gases in mine air, temperature of mine air and of the belt conveyor components, as well as some other factors associated with the burning process. This study discusses the structure and purpose of the belt conveyor fire detection systems within the mine automation and dispatching control. Such systems include: automated gas control and conveyor control. The structure and purpose of the mine fire alarm system are discussed. The capabilities of fire protection systems to detect early signs of fire hazards in roadways equipped with belt conveyors are analyzed, and their advantages and disadvantages are listed.

Keywords: coal mine, ore mine, belt conveyor, exogenous fire, air and gas control, air and gas protection, early fire stage, early fire signs.
