Mechanised roof supports series KM1000OMT is intended for operation together shearer and AFC on seams with thickness between 3,0 to 5,0 m with inclines of up to 30 ° along and up to 10 ° across, with pressure high roofs. Roof support consists of two-legged sections equipped with 4-link connection with the rear shield and canopy, hinged tip. The supports are equipped with face support mechanism.
Mechanised roof supports series 2KM800OMT are intended for operation together shearer and AFC on seams with thickness between 1,7 to 4,0 m with inclines of up to 30 ° along and up to 10 ° across, with pressure average roofs. Roof support consists of two-legged sections equipped with 4-link connection with the rear shield and canopy, rigid tip with pull-out extension. On seams with thickness over 2,5 m the supports are equipped with face support mechanism.
Mechanised roof supports series 2ОМТ01 and 2ОМТ41 are representatives of roof supports family 2OMT are intended for operation together shearer and AFC on seams with thickness between 1,4 to 3,0 m (2ОМТ01) and 1,4 to 3,5 m (2ОМТ41) with inclines of up to 25 ° along and up to 10 ° across, with pressure high roofs. Roof support 2ОМТ01 consists of four-legged sections with canopies rigid or hinged tip; rear shield is connected to the base by one-lever system of direct and cross-section stability. Roof support 2ОМТ41 consistsof four-legged sections with 4-linkconnection with the rear shield and canopy, rigid or hinged tip (on seams with thickness over 2,5 m the supports are equipped with face support mechanism).
Mechanised roof supports series OMT130GSV is intended for operation on thick steep seams by horizontal layers with top level caving. This work is done by a shortwallwith one roadway at the seam floor. Coal mining is done onto the rear AFC. Depending on mining and geological conditions the roof support is supplied with hinged or sliding hinged front canopy extension, which are in turned equipped with a face support mechanism that considerably improves conditions of the opened roof. Roof support is also equipped with devices for movement of rear AFC in process of coal mining and support movement. The roof support is a walking type consisting of two-legged sections, which are connected at the canopies to ensure direct travel. Supports are pressing against the floor with separate legs stands.Hinged guard, connected to the canopy uses a ram to let the coal through from top level caving. Mutual supports and legs travel is carried out by specialised rams.
Mechanised roof supports series OMT147 on the basis of supports 1М147 and М147С are intended for operation together shearer or plough and AFC on seams with thickness between 0,8 to1,5 mwith inclines of up to 30 ° along and up to 10 ° across, with different types of roofs, including difficult to cave. Roof support consists of two-legged sections equipped with 4-link connection of two bases with the rear shield and canopy, rigid, rigid combined or with hinged tip with pull-out extension. Movement of the supports is done by chess or stepped system. Both sides of canopy and rear guard of roof support are equipped with draw-out side flaps to control the stability of the support in the seam and to protect against entry of coal fines.
