Substantiation of parameters of coal unloading process onto conveyor using shearer drums

In this article the process of coal unloading from the face's fracture zone to the conveyor using shearer drums is presented. The effect of the form and dimensions of the sectional area of the loading window and the height of the conveyor's edge surface in the working zone of the rear shearer drum on filling with coal of the auger's intervane space and the effect on circulation of the broken-down coal are analyzed. Estimations and directions of further studies of the coal unloading process from the fracture zone to the face conveyor are proposed.
