Device for determining the cutting horizon of a mining extraction system, and pan element therefor
First Claim
1. A device for determining a cutting horizon of an associated mining winning system comprising:
- a movable conveyor including individual pan elements, each pan element having a conveyor pan having an upper run and a lower run, and a guide section installed on a working face side of the conveyor pan as a machine guide for an associated winning machine, andat least one optical detection sensor having a sensor head which is received in a sensor carrier and can be pressed by at least one pressure means against an associated coal/basement rock boundary layer which is to be sensed,wherein, the individual pan elements are distributed over a length of the conveyor, at least one pan element is configured as a sensor pan which is provided with a protected recess in the pan which is open to the associated basement rock and in which the sensor carrier is arranged such that the sensor carrier can be disassembled together with the sensor head.

Abstract
The invention relates to a device for determining the cutting horizon of a mining winning system, having a movable conveyor which is composed of individual pan elements, and having at least one optical detection sensor which has a sensor head that is received in a sensor carrier and can be pressed with at least one pressure means against a coal/basement rock boundary layer. In order to improve the sensing and working reliability, over the length of the conveyor, a plurality of pan elements are configured as sensor pans which are provided with a protected recess which is open to the basement rock and in which the sensor carrier is arranged or can be arranged such that it can be disassembled together with the sensor head.

3. A pan element for a conveyor of a mining winning system, comprising:
-
a conveyor pan with an upper run and a lower run, a guide section installed on a working face side of the conveyor pan as a machine guide for an associated winning machine, and a protected recess in the pan open to an associated basement rock for dismantlably receiving a sensor carrier for an optical detection sensor which can be pressed by at least one pressure means onto an associated boundary layer which is to be sensed, for sensing the associated coal/rock boundary layer. - View Dependent Claims (4, 5, 6, 7, 8, 9, 10, 11, 12, 13)
