ABSTRACT:
A tensionable dowel for reinforcing walls and/or roofs in excavations such as mines and tunnels is described. The dowel is particularly useful in coal mines where mine walls or roofs are subject to failure. The dowel is fabricated in fibre reinforced engineering plastic and is used with a threaded nut for tensioning the dowel in the wall or roof.
Also described is a process for manufacturing the dowel as well as a method for reinforcing walls and/or roofs by inserting the dowels therein.
