1. 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.
