Study on Early Warning System of Coal and Gas Outburst [PDF]
The Open Electrical & Electronic Engineering Journal, 2013 Coal and gas outburst is an extremely complex and serious gas dynamic phenomenon. Therefore, building an early warning system based on computer system, safety monitoring systems of coal mines and local area network is a precondition for effectively preventing coal and gas outburst.
