This paper will introduce the application of new disasterprone gas integrated monitoring system in mine disaster prevention. 2. Presentation of new integrated monitoring and control system for disaster gas .
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.
2)A coal mine system which replaces the traditional coal mine monitoring system which tend to be wired network system. 3)The underground system also collects temperature, humidity of coal mine through sensor nodes in mine. 4)To check the presence of methane gas inside the mine. 4. Review of Literature
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
the problems, we designed a coal mine safety monitoring system based on wireless sensor network, which can improve the level of monitoring production safety and reduce accident in the coal mine. Zigbee technology provides a direction for scientists who commit to solve the safety monitoring problems of coal mine.
