Ground Support Mining Equipment MacLean Engineering
The underlying design philosophy that made the MacLean scissor bolter transformational in the hard rock mining industry was and remains quite simple – make the act of installing roof bolts less physically grueling and dangerous to operators, while not sacrificing proximity to the face like you see with the boom bolting approach to ground In the first part of this study, the relationships between rock bolts and rock mechanics as well as the positive outcomes of the usage of rock bolts applied in underground mining and construction have been investigated All commercial rock bolts available on the market, automated or none automatedMechanization and Automation of Rock Bolting in MinesMuck Ore or waste rock that has been broken up by blasting Mucking The process of removing the muck from the face Nipper A miner’s helper, usually a trainee Brings supplies, puts bolts together, assists Ore A mix of rock and valuable minerals that can be mined at an economic profit Portal The entrance to the mine at the surfaceGlossary of Hardrock Mining Terms

Cable support guidelines for underground hard rock mine
The objective of this thesis is to expand upon the existing database of cable support practice, and develop revised design criteria for the support of underground openings A new empirical database of 46 supported case histories was assembled from a six month field study,involving visits to 13 mines in Western Canada, the United States, and Ireland A comprehensive review of current cable Installation of resingrouted rockbolts in hard rock mining About 10% of the resingrouted rockbolts that were installed in the last quarter of 2015 were installed incorrectlyv117n4a3 Installation of resingrouted rockbolts in hard system for hard rock mines with a mining height of between 09 m and 12 m (ULP Project) The rock bolting system required development of fully mechanized, remote controlled rock bolting rig, novel rock bolts and a pumpable, fastacting resin grout to secure the boltsDevelopment of a remote control rock bolting system for
