Description
Summary:Raise boring machines are used for excavation of shafts and other vertical structures in mining and civil engineering elds for material, human transportation and ventilation purposes. RBM uses a small diameter drill rod, around 230350 mm to drill a pilot hole down to the required depth. Once the pilot hole has been drilled to the desired depth, a reamer is attached to the drill rod. The reamer is then pulled back up to the upper level, creating a round shape. This continues operation provides a faster advance rate than other methods. The exibility in different angles and diameters is a great advantage compared to drill and blast excavation method. RBM creates a shaft with smooth walls which usually does not require lining in an appropriate geology. The hole is more stable than a drilled and blasted method and has better air ow, making it ideal for ventilation shafts.
