摘要:
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.
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.

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.

The present invention provides a method and apparatus for arriving at true relative amplitude destretched seismic traces from stretched seismic traces. The method compensates for offset varying reflection interference effects due to normal moveout. Stretch factors β and also input spectra are determined for NMOR stretched seismic traces. Estimates are then made of stretched wavelet spectra from the input spectra. A destretched wavelet spectra is then obtained. Shaping correction factors are determined by taking the ratio of the destretched wavelet spectra to the stretched wavelet spectra and are applied to the input spectra of the stretched traces to arrive at a destretched trace spectra. True relative amplitude scaling factors are computed by taking the ratio of a true relative amplitude property of the destretched wavelet spectra to a corresponding true relative amplitude property of the stretched wavelet spectra. Finally, the true relative amplitude scaling factors are applied to the destretched trace spectra to arrive at true relative amplitude destretched seismic traces.

A fluid friction clutch for use in differential gears of motor vehicles having a sliding member which has a adjusting disc which changes the spacing of the clutch plates, which adjusting causes the clutch plates to approach closer to one another and increases the clutch torque provided by a viscuous fluid of the fluid of the clutch. Adjustment takes place via starting slopes which are assigned to a cam driving connection employing a special development of the starting slopes with the torque characteristics being changed in a predetermined manner.

A system and method for attenuating noise in seismic data representative of a subsurface region of interest including receiving a seismic dataset representative of seismic signal or seismic noise and a seismic dataset representative of seismic signal and noise, transforming them into a domain were they have sparse or compressible representation, comparing the sets of coefficients to identify desirable coefficients in the set of coefficients representing the signal and noise dataset, selecting the desirable coefficients to produce an improved set of coefficients, and inverse transforming the improved set of coefficients to produce a modified seismic dataset. The modified seismic dataset may be noise-attenuated seismic data or may be a noise model that is subtracted from the original data to produce noise-attenuated data.
