Metallic mineral/ore prices recently faced with dramatic decreases due to general global trends. Therefore, many metal mining companies in all over the world faced with the problem of shutting down or shrinking their operations, One of the solutions to this problem is to use mechanical miners, such as roadheaders, continuous miners, impact hammers and tunnel boring machines. for ore extraction and development drivages. Since these miners allow for continuous operation, it is expected that mechanization of mines with mechanical miners would increase the productivity, decrease the production cost and be competitive.
