Telemetry in the Mining Industry

Abstract

Telemetry Systems in Mines has dual purpose meant for measurement of physical parameters as well as to control impending dangers. The Telemetry used in mines is of wired system and continuously indicates the presence of both explosive gases like Methane and noxious gases like Carbon monoxide. The Telemetry also indicates the continuous value of Air velocity and the status of underground machinery like booster/auxiliary fans, pumps, coal cutting machine etc. The paper indicates the type of Telemetry required for Indian mines and the present status in Indian coal mines. It also indicates telemetry required for non-ferrous underground mines.
