Abstract
A surface mining and testing apparatus and system provides for the adaptation of a surface miner to the specific geological conditions of a new area of use. The special features of the surface miner are the arrangement of the milling roller (5) in front of the chassis (1) in the direction of mining, the undershot direction of rotation of the milling roller (5), as well as the adjustability of the milling roller (5) in its height and transverse slope in relation to the level. These functional features are accomplished with the testing apparatus in order to obtain the same kinematic conditions as in the surface miner. To make it possible to extrapolate the results obtained with the testing apparatus to the surface miner, the parameters overall weight, drive output and throughput of the testing apparatus are used as constant, lower ratios in relation to the surface miner. The circumferential velocity of the cutting tools (13) and the force acting on each of the individual cutting tools (13) shall be equal in the testing apparatus and the surface miner. To achieve this, the velocity of travel of the apparatus, which is also the rate of feed, as well as the speed of rotation of the roll…
