Get MoreThe mine shaft radio communication system is desgned for wireless transfer of verbal information between a hoisting machine operator or a cager working at the edge of the shaft and an operator of the mine-cage on any level within the shaft. Moreover, the system enables communication between the operators of the mine-cage and the shaft bottom.

This mine will increase production to enable Uralkali to replace the depleting ore reserves of the
Get MoreMine Shaft Wireless Communication System is designed for coordinating actions of technological personnel and operators of mine hoisting machines when carrying out work on descent and ascent of people, audits, inspections and repair work in mine shafts, monitoring condition of sensors of lifting vessels (mine cage or skip) and issuing control signals to control circuit of mine hoisting machines.
Get MoreIn most countries where mining is conducted it is governed by legislative authorities, and is subject to a set of regulations. This International Standard cannot, and it is not intended to, replace any of these regulations, but it is intended to supplement these regulations by providing rational guidance to enable engineers to design appropriate structures for mine shafts.
