Its mine ventilator equipment system, mine hoist equipment system, mine drainage equipment system and mine air compressor equipment system, wholly named as underground main configuration equipment system, are indispensable for mine production of major equipment. The stand or fall of its main configuration equipment system is directly related to the miners’safety, production safety and benefit, so how to realize and safeguard its key equipments in safe and reliable operation has always been an important research topic in the field of mine safety production. At present, a lot of researches into the field of underground mining equipment’s monitoring and fault diagnosis have got results, but less researches have been done on an integrated monitoring platform which can unify the multiply underground safety monitoring systems and gas control and other safety monitoring system.
