Particularly as the mining depth increases, the ground stress increases linearly or nonlinearly, the ground temperature rises, and the rock mass becomes hard and brittle, which brings about many technical problems in transportation, ventilation and cooling, and filling processes, further increasing the difficulty of making hard rock mines ...
Since his first job in 1977 with Swedish mining company Boliden before joining ABB, Bengt Hedlund has spent more than 45 years developing world-renowned technologies focus on hoisting aftermarket and service that have made underground mining safer and more reliable. Bengt talks about hoists with enthusiasm, curiosity and care.
experience of mine hoists ðcovers over a century. Up to 1936 the company concentrated on the drive and control systems for mine hoists, while various engineering firms were responsible for the mechanical parts. Over the years mine hoists of various types were developed. A major advance oc- curred in the mid 1940s with the introduction
Mine hoists command systems are safety-related electrical control systems (SRECS) in the sense that they implement safety functions in order to maintain the safety of the controlled equipment. A safety function is a function of a machine whose failure can result in an immediate increase of the risk (ISO 12100, 2010). As a SRECS, it uses ...
