Abstract
The construction techniques and anchoring mechanism of pre-anchoring fissured stope hangingwall of some copper mine in China by fully-grouted cable bolts are explored. The construction stages such as drilling anchor holes, making anchorage cables and cement mortar, grouting, and curing are expounded. A combined action mechanism of pre-anchoring fissured stope hangingwall by fully-grouted cable bolts is presented. The achievements are helpful and beneficial to the design and construction of rock engineering projects which need anchoring reinforcement, such as slopes, tunnels, deep foundation pit, caverns, and underground mining.
