摘要: A cutting apparatus suitable for creating tunnels and subterranean roadways includes independently pivoting supports that each carry a respective independently pivoting arm and a rotatable cutting head. Each cutting head via the supports and arms, is configured to slew laterally outward in a sideways direction and to pivot in a vertical upward and downward direction. The supports and arms are mounted on a linear moving sled carried by a main frame.

摘要: A longwall support in a mine that comprises a plurality of longwall support units. The longwall support units are supported relative to a conveyor by stays that comprise cylinder-piston units. A control system with data acquisition, data storage, and programming is used to adapt the distribution of the staying forces over the length of the longwall, the sum of the staying forces acting upon the length of the longwall (total staying force), and the distribution of the advance forces over the length of the longwall continuously to the desired position of the conveyor. As a result, it is possible to influence the total staying force by the number of the stays with respect to an adjustable maximum, or the total staying force by controlling the longitudinal forces of the individual stays, or the total staying force as a function of at least one of the end positions of the conveyor.

摘要: A lift cylinder arrangement is disclosed for a hydraulic support frame for underground mining. The support frame has a lift cylinder for lifting the base shoes during advancing, which is supported on the one hand on a return rod and on the other hand, in a pivoting manner, with an end supporting head to a drawbar connected to the base shoes. In order to allow a simple, rapid and reliable connection between the supporting head and the drawbar, the supporting head is connected to the drawbar by a plug-type locking system comprising two plug-type locking elements, which include first locking notches on the drawbar, and arranged complementarily thereto second locking notches on the supporting head, whereby the plug-type locking elements engage in at least one of the locking notches with clearance.

摘要: A shield support frame is constructed from main shoes (5) on the ground, hydraulic props (6) and a main canopy (7) borne by them and a gob shield (8) borne on guide links (10). On the face side, there is a front cantilever (24) linked so as to be adjustable in height from the main canopy (7), on which a sliding canopy (25) is guided so as to be able to slide in the direction of the face. On the ground, an adjustable baseplate (21) is arranged at a distance in front of the main shoes (5) and connected via a horizontal joint axle (22) to the extending part of the shifting gear (3). Front assembly props (23) mounted on the adjustable baseplate (21) support the sliding canopy (25). The tip of the plate of the adjustable baseplate (21) is lifted from the ground during forward movement.

摘要: The mobile stope support apparatus comprises a number of individual units (10) which are interconnected by hydraulic cylinders (12). Each of the units (10) has a series of upright, double-acting legs (20). The legs (20) have independent bases of rounded shape and they are pivoted to an overhead canopy (22) which can be raised and lowered by appropriate actuation of the legs. Each unit also has a fore-and-aft hydraulic cylinder (34) which is connected to a common rail (37), the cylinder (34) being pivotable, by the action of a cylinder (36) in an upright plane to raise and lower the rail. By appropriate sequential operation of the various cylinders, the units can be advanced in turn to advance the whole apparatus. In addition, by appropriate operation of the cylinder (36), the front legs (20) can be lifted off the footwall to facilitate movement of the unit over a rough or uneven footwall.

摘要: Apparatus for mounting ancillary equipment between two relatively movable members of, for example a mine roof support, comprises two substantially parallel arm members pivotally mounted between the two relatively movable members, two rotatable members secured one to each arm member, and at least one cross member pivotally mounted at opposing ends to the rotatable members. The members of the apparatus are arranged so that the axes of rotation of the rotatable members, the axis about which the arms pivot, and the axes about which the cross members pivot, are each transverse to the other two. This arrangement can be used to provide a mine roof support with an operating platform having mountings which have a degree of movement akin to a universal joint.

摘要: A so-called externally-situated advance mechanism is arranged between the floor sills of adjacent mine roof support units. The advance mechanism includes two laterally-spaced guide rods, and two advance rams positioned above the guide rods. The front ends of the guide rods are connected to a head-piece. A bridge is connected to the two guide rods at a distance behind this head-piece. The piston rods of the two advance rams act on this bridge. The cylinders of the rams are connected, at a distance therebehind, to brackets fixed to the floor sills. Said brackets form guides for the guide rods.
