摘要:
In the method according to the invention and the arrangement or according to the invention for extracting extraction products in underground mining operations using the caving method, the extraction products (20) collapsing in an upper gate area (10) are extracted via at least one extraction funnel (13) or the like into an extraction path (14) driven below the gate and are transported away therein by means of an extraction conveyor (15). According to the invention the extraction funnels (13) are arranged laterally beside the extraction conveyor (15) and lead at their lower end into a ramp surface (17) inclined towards the extraction conveyor, the extraction products extracted from the gate through the extraction funnels being transported slidingly over the inclined ramp surface to the extraction conveyor. The inclined ramp surface is preferably formed by a loading ramp (22) which is so arranged in an extraction chamber (16) branching off laterally from the extraction path that its one end (19), disposed higher, is located below the extraction funnel and its other end (23), disposed lower, forms an outlet (21) towards the extraction conveyor.

An arrangement for extracting extraction products in caving in which the extraction product is extracted downwards through an extraction funnel into an extraction path and from this is transferred onto an extraction conveyor arranged in a conveyor path, in which arrangement the extraction path extends transversely between the conveyor path and an auxiliary path parallel to this, a loading ramp is arranged in the extraction path which forms a ramp surface orientated transversely to the conveying direction of the extraction conveyor and inclined towards it. The extraction path is provided with a rail guidance attached to the bottom and extending in the area between the auxiliary path and the conveying path, on which the loading ramp is guided and along which it can be moved by a displacement drive (20) in the direction of the conveyor path and in the opposite direction.

In the arrangement in accordance with the invention for extracting extraction products in caving in which the extraction product is extracted downwards through an extraction funnel (10) into an extraction path (11) and from this is transferred onto an extraction conveyor arranged in a conveyor path, in which arrangement the extraction path extends transversely between the conveyor path (13) and an auxiliary path (12) parallel to this, a loading ramp (16) is arranged in the extraction path (11) which essentially forms a ramp surface orientated transversely to the conveying direction of the extraction conveyor and inclined towards it. In order to be able to control the quantity of extraction material extracted through the extraction funnel and to be able to clear the extraction path in a particularly simple manner if it is blocked with extraction material, the invention envisages that the extraction path is provided with a rail guidance (19) firmly attached to the bottom (15) and extending in the area between the auxiliary path and the conveying path, on which the loading ramploading ramp (16) is guided and along which it can be moved by means of a displacement drive (20) in the direction of the conveyor path and in the opposite direction.

A mobile mining machine includes a movable machine base frame having a boom, a swinging device for swinging the boom, and a tilting device for tilting the boom. At least one tool drum is coupled to the boom for rotation about a drum axis and rotatable tool carriers are arranged on a circumference of the tool drum. The boom has a supporting arm, on which the tool drum is mounted, and a separate swinging base, which is swingable about a swing axis in relation to the machine base frame by the swinging device. The supporting arm and the swinging base are connected to one another by a system of guide bars, by way of which a setting angle of the drum axis in relation to the swing axis is adjustable.

A mining machine for extracting seam-type or mass-deposit mineral materials includes a conveyor for carrying away mined material, a machine frame that can be moved along the conveyor and that includes at least one drum, which is equipped with extracting tools, is rotatable about its drum axis and is adjustable in height relative to a machine frame by a swivel arm. The drum axis of the drum is parallel to the direction of travel of the mining machine, and the extracting tools are mounted in groups on tool carriers which are arranged on the circumference of the drum so as to be rotatable about rotation axes disposed transversely in relation to the drum axis.

A method for producing a handle apparatus includes providing an elongate handle base body which has a central receiving space in which electronic components are arranged, applying a sealing joint around the central receiving space and attaching a handle cover to the elongate handle base body. When the handle cover is attached, the sealing joint is compressed so that the central receiving space is sealed via the sealing joint. An inlet opening and an outlet opening are formed on opposite ends of the central receiving space. The handle apparatus is oriented vertically and filled with a liquid sealing compound via the inlet opening, wherein gases which are present in the central receiving space are discharged via the outlet opening. A corresponding handle apparatus is also disclosed.

A demultiplexer 630 routes only one or more transport stream packets with a single packet identifier value to each physical layer pipe. A header compression unit 620 replaces the packet identifier of the transport stream packet with a short packet identifier of one bit length indicating at least whether the transport stream packet is a NULL packet.
