Description

Verfahren zur Gewinnung von Kohle Schwierig ist die Gewinnung der Kohle .aus: dien zum Teil sehr dünnen Flözen von beispielsweise ¢o bis 6o ,am Stärke.Process for the extraction of coal The extraction of the coal is difficult Coal .from: serve in part very thin seams of, for example, ¢ o to 6o, at the strength.

Aus diesem Grund wird erfindunIgsgemäß. vorgeschlagen., große R,äumie unter Tage auszusprengen, und zwar ohne Rücksicht tauf die ieigentlichen Kohlenflöze und dazwischenliegende Gesiteinslagen:. Es. @enitstehen :dabei große Räume, angefüllt mit Gesteins- und Kohlehaufwerk; und damit die Aufgabe, das Haufwerk unter Tage sielektiv aufzub:ere beny wozu vorzugsweise bekannte Prallmühlen ,oder Rohrmühlen !großen Durchmessiersohne Verweindung von Mahlkörpiern: sich als bestens geeignet ierwiesen haben. Ebenso ist ges möglich, die seliektiwe Aufbiereätugg des Haufwerkes durch bekannte :durchzuführen. Das @dabei ;anfallende feinkörnige Gut, z. B. grießige Kohlte, kaum idann ,pmewmiatisch mit biekarmlten Pre;ßluftfördenamll;aglen ioder n-imt Pumpen aus der Grube zu Talge gefördert werden. jedenfalls. kann. auf d@eis:e Weise in größeren Räumyen die Ge wimungsarbef leichter iaais bisher durchgeführt und leine entsprechenid größere Nwtzlieiistungerzielt werden.For this reason, according to the invention. suggested., capital R, äumie blasting underground, regardless of the actual coal seams and intervening facial inserts: It. @enitestand: large rooms, filled with rock and coal heap; and with it the task of removing the heap underground They can be set up selectively, including preferably known impact mills or tube mills ! large diameters without twisting grinding bodies: proven to be ideally suited ierwiesen. It is also possible to selectively dispose of the debris by known: to perform. The resulting fine-grained goods, e.g. B. gritty Kohlte, hardly idann, pmewmiatisch with biekarmlten Pre; ßluftfördenamll; aglen ioder n-imt pumps are conveyed from the pit to sebum. in any case. can. on d @ eis: e Way in larger Räumyen the Ge wimungsarbef easier iaais carried out so far and accordingly, greater usefulness can be achieved.
