Influence of Matching Parameters of Scraper Conveyor on Loading Efficiency of Shearer
Shearer drum plays the role of cutting and loading coal in mining.With the in-depth study on the power of shearer,the current cutting capacity has basically met the requirements,but there are still many problems in the loading efficiency,and the research on the loading efficiency of medium and thick coal seam is even less.The simulation model of double-drum shearer in medium and thick coal seam is established based on the particle displacement mode and the contact between particles.The influence curves of factors such as the height of the shearer scraper conveyor,the width of the middle groove and the horizontal distance between the middle groove and the coal wall on the coal loading efficiency are calculated through the simulation,and the influencing reasons are further analyzed.It lays a foundation for the improvement and research of the loading efficiency of double-drum shearer in the future.
