Selection of a Practicable Shearer Loader Based on Mechanical Properties of Coal for Parvadeh 1 Mine / Wybór wrębiarko-ładowarki w oparciu o właściwości mechaniczne węgla w kopalni parvadeh 1

Abstract

Obtaining the maximum productivity with minimum energy consumption in coaling faces, directly depends on selection of the suitable shearer loader machine with the most effective and fitness picks for it and also their arrangement on cutter head. In order to select appropriate shearer loader machine, some in-situ tests have been carried out on C1 coal seam of Parvadeh1 long wall mine located in east of Iran. Studying of the mechanical properties of C1 coal seam demonstrates an extremely low strength of coal. Thus, it was concluded that a kind of two drums shearer (model EL600) with the conical picks can be effectively worked.
