Abstract:
A cable bolt for providing support and balance to a rock mass, comprising: a multi-strand cable having a plurality of steel wires being twisted together, said multi-strand cable having a first end portion for anchoring in a borehole of rock mass and a second end portion for being positioned adjacent to the opening of the borehole, a fixture secured to the second end portion of said multi-strand cable, wherein at least one of the plurality of steel wires is made from steel having as steel composition: a carbon content ranging from 0.20 weight percent to 0.95 weight percent, a silicon content ranging from 0.5 weight percent to 2.0 weight percent, a manganese content ranging from 0.40 weight percent to 1.0 weight percent, a chromium content ranging from 0.0 weight percent to 1.0 weight percent, a sulphur and phosphor content being limited to 0.025 weight percent, the remainder being iron and unavoidable impurities, and said steel has as metallurgical structure: a volume percentage of retained austenite ranging from 4 percent to 25 percent, the remainder being tempered primary martensite and untempered secondary martensite.

Claim (Index 13):
A process of manufacturing a multi-strand cable bolt having energy absorption of at least 20 KJ/m for a multi-strand cable bolt having a diameter of about 15.4 mm, and at least 30 KJ/m for a multi-strand cable bolt having a diameter of about 17.8 mm,\n said process comprising the following steps: a) selecting a steel wire with steel composition:\n a carbon content ranging from 0.20 weight percent to 0.95 weight percent, \n a silicon content ranging from 0.5 weight percent to 2.0 weight percent, \n a manganese content ranging from 0.40 weight percent to 1.0 weight percent, \n a chromium content ranging from 0.0 weight percent to 1.0 weight percent, \n a sulphur and phosphor content being limited to 0.025 weight percent, \n the remainder being iron and unavoidable impurities, \n b) austenitizing said steel wire above Ac3 temperature between 920\u00b0 C. and 980\u00b0 C. during a period less than 120 seconds, c) quenching said austenitized steel wire between 20\u00b0 C. and 280\u00b0 C. during a period less than 60 seconds, d) partitioning said quenched steel wire between 320\u00b0 C. and 500\u00b0 C. during a period ranging from 10 seconds to 600 seconds, e) cooling down the partitioned steel wire to room temperature, f) twisting the quenched and partitioned steel wires into a multi-strand cable, g) cutting the multi-strand cable into a preselected length, h) adding a fixture to an end portion of said multi-strand cable.
