         28 . A mining machine according to  claim 27 , wherein the rotation axes of the tool carriers of the first drum and of the second drum face towards each other. 
     
     
         29 . A mining machine according to  claim 27 , wherein a rotary drive for the two drums is positioned centrally between the first drum and the second drum of the drum pair. 
     
     
         30 . A mining machine according to  claim 27 , wherein the tool carriers on the first drum rotate in the opposite direction to the tool carriers on the second drum. 
     
     
         31 . A mining machine according to  claim 21 , wherein two height-adjustable and tiltable swivel arms, each supporting a drum pair, are disposed on the machine frame. 
     
     
         32 . A mining machine according to  claim 21 , wherein the swivel arms are adjustable in height by toggle lever joints. 
     
     
         33 . A mining machine according to  claim 32 , wherein an actuating cylinder is assigned to each toggle lever joint. 
     
     
         34 . A mining machine according to  claim 33 , wherein the swivel arms and the toggle lever joints are mounted on slides, which are held in a tiltable manner in guides on the machine frame. 
     
     
         35 . A mining machine according to  claim 34 , wherein the actuating cylinders are articulated, at one end, to the slide and, at the other end, to a middle joint of the toggle lever joint, as a result of which the associated swivel arm and the drum axis of the associated drum is adjustable in height.
