摘要： Die Erfindung betrifft eine Hydraulikfräse (0) zum Anbau an die Ausrüstung einer Bau- oder Bergbaumaschine, mit mindestens einer Schneidwalze (11), mindestens einer Schwungmasse (12) zur Aufnahme kinetischer Energie und mindestens einem hydraulischen Motor (6) zum rotatorischen Antreiben der Schneidwalze (11) und der Schwungmasse (12). Die Erfindung setzt sich zum Ziel, eine kompakte und gewichtsgünstige Hydraulikfräse (0) zu schaffen, deren Schneidwalze (11) über ein besonders hohes Trägheitsmoment verfügt. Dieses Ziel wird dadurch erreicht, daß die Schwungmasse (12) mit einer höheren Winkelgeschwindigkeit als die Schneidwalze (11) rotiert wird. Ein Getriebe (2) soll ferner die genannten Winkelgeschwindigkeiten in ein festes Verhältnis zueinander setzen.

摘要： The invention relates to a method and to a device for monitoring the track of a cutting extraction machine (1), which is used in particular in coal mining and can be displaced during longwall mining in a longwall face equipped with face conveyors (9) and longwall advancing (12, 13) along the face (10). The underlying object of the invention is to create a method and a device which make it possible, despite extremely poor visibility conditions, for example in the track of the extraction machine, to detect present obstacles in the form of lowered canopies or drooping folding canopies, sliding canopies or other additions to the lining or overloads of the conveyor in order to take measures for avoiding interruptions in the operation in a timely manner. In order to achieve this object, according to the invention the track of the extraction machine (1) is scanned using a radar measuring device (14) associated with the extraction machine (1) and upon detection of an obstacle an alarm is triggered and/or an invention in the controller of the extraction machine (1) takes place.

摘要： The invention relates to a method for controlling a cutting extraction machine that can be displaced along a coal face in longwall mining, wherein the radiated heat of the working face (4) newly exposed by the extraction machine is observed by means of an infrared camera (10), and control data for the subsequent extraction travel is generated using said observation. In order to make said method error-free and better suited for practical application, the invention proposes that the observation of the radiated heat is done perpendicular to the working face (4) at a minimum distance from the cutting tools of the extraction machine, and that a guiding layer package (X) having a characteristic sequence of boundaries between layers of differing heat conductivity is determined, and that the course of said guide layer package (X) relative to the boundaries of the face is determined at the end of each extraction travel using the heat images, and that the control data for the next extraction travel of the extraction machine is generated using said course of the guide layer package.

摘要： The invention relates to a shearer loader for mined extraction in longwall mining, comprising a machine body (1) that can move along a longwall conveyor (2) in the longitudinal direction of the longwall, and at least one cutting drum (4) which is carried by a carrier arm (3) fixed to the machine body (1) in a pivotable manner, is mounted on the free end of the carrier arm (3) such that it rotates about an axis extending parallel to the roofs and perpendicularly to the face, and can be driven by a drive motor associated with the carrier arm (3) by means of a train of gears arranged inside the carrier arm (3) and a planetary gearbox on the free end of the carrier arm (3), the gearbox housing (5) of which, connected to the end section of the carrier arm (3) in a non-rotatable manner, consists of axially successive annular housing sections ( 5a, 5b, 5c) held together by screwed bolts (6) on the periphery thereof. In order to be able to detach the gearbox housing (5) and the planetary gearbox contained therein as a whole from the carrier arm (3), in such a shearer loader, the housing section (5c) of the gearbox housing (5), adjacent to the carrier arm (3), comprises a separate attachment flange (7) which can be fixed to a complementary mating flange (10) on the free end of the carrier arm (3), by means of a separate screw connection (8, 9).
