Abstract: With the promotion of production capacity of Tunlan mine,large gangue in run-of-mine coal becomes bottleneck of restricting production in raw coal preparation workshop.Because large gangue influence,the accident is frequent in the production process as blocking,stopping up,pressing,brings about serious consequences to production and equipment maintenance.At the same time also causes unfavorable factors such as high production costs,great labour-intensive of workers and so on.According to trajectory and physical characteristics of large gangue of run-of-mine coal in Tunlan coal mine in the transport process,puts forward extend the belt conveyor nose of main shaft,increase equipment of the bar screen and other,improving technology,successfully removes from large gangue,provides the safeguard for subsequent job of raw coal preparation.
