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.

Zapewnienie maksymalnej wydajności pracy w rejonie przodka połączonego z minimalnym zużyciem energii związane jest z wyborem odpowiedniego rodzaju urządzenia (wrębiarko-ładowarki), zapewniającego optymalną ilość i układ noży wrębowych. W celu wyboru optymalnej maszyny urabiającej, przeprowadzono badania in situ w złożu węgla C1 w kopalni Parvadeh 1 we wschodnim Iranie, gdzie wydobycie prowadzi się metodą ścianową. Badanie właściwości mechanicznych węgla C1 wykazało, że jest to węgiel o niskich parametrach wytrzymałościowych. Stwierdzono, że do urabiania tego typu węgla optymalnym rozwiązaniem będzie zastosowanie dwóch wrębiarek bębnowych (model EL600) wyposażonych w stożkowe noże wrębowe.
