Study on Mining Technology in Intelligent Workface of Wannian Colliery

Intelligent mining of coal face is the basis to achieve automatic mining, electro-hydraulic control technology is the core of the intelligent mining. The 13266 coal face of Wannian colliery used the PM32 electric hydraulic control system of hydraulic powered support, realized the automatic drop support, move support, upper support and the monitoring and display of roof pressure, also realized the determination of shearer position, the control of cutting height and running speed, remote control operation and remote run, improved the level of automation.
