METHOD OF MINING COAL BEDS OF PREDETERMINED CUTTING DEPTH WEB

摘要

the invention concerns a procedure for the extraction of coal seams with defined schnittiefenvorgabe in expected extraction using a plough, and a conveyor running along a face for a defined schnittiefenvorgabe by out of schreitzylindern advanced willon the one hand and, on the other hand, the conveyor in parallel to the face conveyor and ausbaugestellen conditions. the advance in dependence on a single defined teilhu00fcben kolbenhub carried out the schreitzylinder through wegmeu00dfsignale controlled. after reaching a predetermined maximum.gesamtkolbenhubs is associated with the respective schreitzylinder chock automatically eingeraubt to gesamtkolbenhub brought forward and then the hubweg set while the schnittiefenvorgabe corresponding teilhu00fcbe a ausgleichsmau00df of the anlenkpunkten de r schreitzylinder existing medium-sized mechanical game is enlarged.in the face, a certain abbaufrontverlauf as abbaufrontverlaufsendwert (y) with respect to a pivot point (z) on the side of a main or hilfsantriebs plough is so established that the abbaufrontverlaufsendwert a (y) through the pivot point (z), and the just a multivendor 90 degrees compared with the previousalso on a straight line (x) with the pivot point (z) of the first abbaufrontverlauf gently, so that...
