Analysis of Deformation of Mining Chains Based on Motion Tracking
This paper presents the possibilities of using a compact digital camera, which is amateur class of equipment, to a simple analysis of the deformation of mining chains during the tests performed at percussive, dynamic load. When the mining chain works during underground coal-bed exploitation, in the scraper conveyor, which is one of the elements of a longwall system, there could be observed frequent chains fractures due to its dynamic percussive load. It often occurs as a result of an emergency chain locking in the troughs of the chain conveyor. For the purpose of analysis special software was created. Thus it was possible to obtain at low cost, with the assumed accuracy of deformation measurement, deformations as a function of time, without installing on the monitored elements acceleration sensors (e.g. inductive, potentiometric), which were usually destroyed during the tests, mostly due to their low resistance to shock.
