Abstract
The present invention provides device system and a method for monitoring movements of mining conveyances in a mine shaft. One or more sensors that form part of the system may be installed directly on the mining conveyances. The sensors may be accelerometers and are for detecting movements on mining conveyances. The system may analyze the descent and ascent paths of the mining conveyances on guides by recording vertical, horizontal and transverse accelerations. The analysis may comprise associating the movements with position of the mining conveyances on the guides for identification of an anomaly at a specific position.
Claims14
A method for monitoring movements of at least one mining conveyance in a mine shaft for identifying anomalies, the at least one mining conveyance being vertically displaceable along guides in the mine shaft, the method comprising:
- i. providing the at least one mining conveyance with at least one sensor for detecting movements, said at least one sensor being mounted to said at least one mining conveyance;
- ii. operating the at least one mining conveyance upwardly and downwardly along the guides;
- iii. detecting movements with the at least one sensor to generate a signal;
- and
- iv. analyzing the signal as a function of position of the mining conveyance on the guides for identification of an anomaly at a specific position,
- wherein said at least one sensor measures acceleration along a plane perpendicular to a direction of motion of said at least one mining conveyance to thereby produce acceleration data, and wherein said processor associates said acceleration data with said specific position to thereby identify said anomalies.
A system for monitoring movements of at least one mining conveyance in a mine shaft for identifying anomalies, the at least one mining conveyance being vertically displaceable along guides in the mine shaft, the system comprising:
- a) at least one sensor provided on the at least one mining conveyance for detecting movements and generating at least one signal based on said movements;
- and
- b) a processor for analyzing the at least one signal and identifying an anomaly as a function of a specific position of the at least one mining conveyance on the guides,
- wherein said at least one sensor is configured to measure acceleration along a plane perpendicular to a direction of motion of said at least one mining conveyance to thereby produce acceleration data, and wherein said processor is configured to associate said acceleration data with said specific position to thereby identify said anomalies.
