Networking of Monitoring and Control System for Safety Production of Coal Mine

The paper analyzed exsisting situation of safety production of township coal mine in China: its coal production is 37.8% of the total,while the number of death accidents and persons is 73.5% and(74.1%) separately,and the death rate per million tons is seven times of the one of national key coal mine.The causes leading to frequent accidents of township coal mine includes laggard equipments,imperfect mine system,scarcity of professional technical personnel,lag of safe education and training,non-implementation of safety responsibility,slack field management and imperfect troubleshooting,and laggard equipments and low degree of mechanization,automation and informationization are main causes.Networking of monitoring and control system for safety production of coal mine is an important measure to enhance supervision for safety production of coal mine.The paper put forward networking methods of monitoring and control system for safety production of coal mine: central station or host computer should transfer related monitoring and control information to monitoring and control center in time,central station or host computer and monitoring and control center should have Ethernet interfaces according with IEEE802.3 protocol and so on.
