Slope Hoists and Surface Mining Underground mining ropes are not our only business. Northern Strands can also supply wires ropes for Slope Hoists and Surface Mining. Flattened Strand, 6 strand, and 8 strand are the most common varieties here. The number of wires, level of compaction, and inclusion of plastic are all part of the design process.
Underground Mining: The Role and Characteristics of Mine Cages Mining is an industry that pushes the envelope in engineering, and things get even more extreme when it comes to underground mining. The use of underground mines is necessary for excavating at depths greater than 60 metres (the point where surface mining turns inefficient).
All cage types are available, including Service Cages, Auxiliary and Trailer Cages, each with many options and alternatives, such as various designs of cage floors, doors, roofs, removable intermediate decks and removable counterweights. Each cage is made from the most durable-yet-lightweight materials, with a heavy emphasis on aluminum.
