An apparatus for the milling cutting of rock, minerals or other hard materials has a tool drum which is rotatably mounted on a drum carrier about a drum axis and on the peripheral shell surface of which are disposed, in distributed arrangement, a plurality of tool carriers, which carry cutting tools and can be rotatingly driven, where their shaft axes run transversely to the drum axis. A first group of tool carriers and a second group of tool carriers are provided, where the rotational direction of the first group is counter to the rotational direction of the second group, and the shaft axes of the tool carriers of the first group and of the second group are oriented at different setting angles relative to the radial direction of the tool drum.

Apparatus for the milling cutting of rock, minerals or other materials

A mining apparatus includes two tool drums, which are arranged rotatably side by side in twin arrangement on a drum carrier and which are respectively provided with a plurality of tool carriers which support cutting tools arranged over the periphery of the tool drums and which can be rotatingly driven and the shaft axes of which run substantially transversely to the drum axle. The shaft axes of the tool carriers of the first tool drum span a first conical surface about the drum axis and the shaft axes of the tool carriers of the second tool drum span a second conical surface about the drum axis, where the conical surfaces are open to opposite sides and are preferably oriented such that they are mutually inclined in an O-arrangement.

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.

Mobile mining machine and method for driving tunnels, roadways or shafts, in particular in hard rock

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 () in the direction of the conveyor path and in the opposite direction.

Arrangement for extracting extraction products in underground extraction operations in caving

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 () collapsing in an upper gate area () are extracted via at least one extraction funnel () or the like into an extraction path () driven below the gate and are transported away therein by means of an extraction conveyor (). According to the invention the extraction funnels () are arranged laterally beside the extraction conveyor () and lead at their lower end into a ramp surface () 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 () which is so arranged in an extraction chamber () branching off laterally from the extraction path that its one end (), disposed higher, is located below the extraction funnel and its other end (), disposed lower, forms an outlet () towards the extraction conveyor.
