Designing a Monitoring System to Observe the Innovative Single-Wire and Wireless Energy Transmitting Systems in Explosive Areas of Underground Mines

Abstract

Suspended monorails are a common mode of transportation for materials and personnel in underground mines. The goal of the EU-funded project “Innovative High Efficiency Power System for Machines and Devices, Increasing the Level of Work Safety in Underground Mining Excavations (HEETII)” is to introduce a single-wire energy transmission system combined with a capacitive-coupling-based wireless transmission system to power the suspended tractor, along with a monitoring system that will monitor the energy network and additional environmental parameters of the mine. Additionally, the monitoring system acts as the wireless communication backbone, allowing for data transmission to surface headquarters, where the data are processed and logged in a central database. This enables operators to detect and take preemptive measures to prevent potential hazards in the mine, improving the overall efficiency of the energy transmission system. This paper describes the additional considerations required for electrical systems in underground mines with potentially explosive atmospheres, as well as the design of the energy transmission system and the monitoring system.

Routing Algorithm for Sensor Network Monitoring the Condition of Mining Equipment

“…IIoT is finding increasing application in the coal mining industry. Wireless sensor networks are being used to monitor the condition of underground machinery and equipment, environmental conditions, and the health of miners working in crude coal mining [2][3][4][5][6][7][8][9][10][11]. Research is being carried out and solutions are being developed for the application of wireless sensor networks for monitoring rock conditions, measuring roof deformation, and using wireless optoacoustic devices to create escape routes in mines.…”
