Development trend of coal mine informatization and automation

SUN Jiping;China University of Mining and Technology(Beijing);  
The paper analyzed accident rate per million tons,death rate per million tons,serious accident rate per one hundred million tons and serious accident death rate per one hundred million tons during 2004-2013.It proposed intelligent unmanned steer methods of rubber-tyred vehicle and electric locomotive,and navigation control method of mine-used robots and disaster rescue robots which mixed with machine vision,laser ranging,radar ranging and velocity measurement and artificial intelligence.It studied characteristics of mine-used machine vision and its application in coal mine.It put forward that underground mobile communication mainly uses 4Gand WiFi technologies,and 5G mobile communication with faster transmission speed and higher working frequency which is more suitable for underground.It pointed out that radio wave with larger radiation power not only ignites gas and electric detonator,but also causes personal injury.It also pointed out antenna with larger transmission power and gain should beinstalled on top of roadway and far away from fixed post operating personnel,so as to avoid radiation for long time.It proposed mine-used robots and disaster rescue robots should employ unmanned rotorcraft with lithium battery and high power micro motor,and technologies of remote wireless control and automatic navigation control of underground robots should be studied.It put forward monitoring and early warning methods for fire disaster in goaf based on gas and temperature remote measuring sensors.It put forward technology requirements of monitoring for preventing coal mining illegally.It analyzed advantages and shortcomings of underground visible light communication.
