Underground mines have changed their operation systems in accordance with the evolution of equipment, the system and method of mining. Transport is also of critical importance in underground mines as is the mining operation itself. The underground transport system of ores, materials, equipment and persons has been developed from
and Under these provisions it is required that high, medium, and low voltage resistance grounded systems include a fail safe ground check circuit. Th e requirements for ground wire monitoring have been in effect since September 30, 1970. They cover all resistance ground ed circuits in underground coal mines.
Jan 01, 2011· CONCLUSIONS A new mine safety monitoring system was developed; it compromises sensitive sensors and ZigBee WSN which is smart, lowcost, lowpower and lowmaintenance. This system can monitor the gas concentration, temperature and humidity and vibration sensitively, carry on the early warning to the potential hazard; reduce loss of life and ...

Aug 31, 2014· The diverse management applications of the GIS space monitoring services, such as correlation, positioning, and realtime alarm, alter the traditional situation, in which coal mine safety production management systems are all PCbased and provide a brand new method for coal mine safety production monitoring and management.
Abstract: The safety of coal mine is an important link in coal mine production,gas disaster is the most harmful for the safety of coal mine production. During the process of mine development, it is very important to measure the gas concentration in mines. For the present of situation of gas concentration monitoring system, this paper proposes a Bluetoothbased coal mine gas concentration ...
Mine winch hoist is the main tool used to send the track train to the designated position for underground and external transmission. Original drive system has below disadvantage: 1. Poor smoothness of speed regulation. 2. Low control accuracy and small speed adjustment range.
Environment monitoring is important for the safety of underground coal mine production, and it is also an important application of Wireless Sensor Networks (WSNs). We put forward an integrated environment monitoring system for underground coal mine, which uses the existing Cable Monitoring System (CMS) as the main body and the WSN with multiparameter monitoring .
the Bureau of Mines. monitoring of the raw coal system, the main fan, and the mine hoist to be integrated into the mine monitoring system, it had to interface to these existing sensor points with a minimum of reengineering. 2. Reliability WFA wanted a reliable system that would operate continuously, so dual processors
