Abstract
This researching project had the aim of: Testing a new mining system performance at narrow coal bed, which uses plough equipment with hydraulic driving devices. Minimising driving power group size to avoid problems regarding with the wall mining-heading transition, decreasing the needed room to house it and thus, simplifying wall mining edge support. The expected goals were: Take advantage of hydraulic driving devices to obtain a good efficiency with a variable and discontinuous load, but without loosing the electric driving devices advantages, consisting on increase driving torque, being the engine blocked Lengthen the mechanical equipment life (chains, driving sprockets, etc) Reach an economic production rate Researching project was developed in El Bierzo basin (leon, Spain), in Grupo Ampliacion, a mining group belonged to Viloria Hnos, S. A. (Author)
