A New Concept for Selective Mechanical Mining of Hard Rock
نویسندگان
چکیده
Over the last several decades mechanical mining machines have developed into highly productive, light weight, mobile machines which are able to economically mine many soft rock ore bodies. Due to the utilization of disc cutters Tunnel Boring Machines, with great mass and limited mobility, have developed the ability to cut the hardest rocks at high production rates. Technological advancements have allowed mini-disc cutters, which require low forces to cut hard rock, to be developed. These mini-disc cutters provide a new option for developing a light weight, mobile machine which can excavate hard rock. This concept and supporting data are presented.

A state-of-the-art review of mechanical rock excavation technologies
The first step in mining activities is rock excavation in both mine development and production. Constant pressure for cost reduction and creating an improved/safe work environment for personnel has naturally resulted in increased use of mechanical excavation systems in many mining operations. Also, mechanical excavation and mining is more compatible with automation, meaning possibility of reduc...
متن کاملInvestigating the Relationship between Various Brittleness Indexes with Specific Ampere Draw in Rock Sawing Process
This study aimed to develop new statistical models for evaluating the specific ampere draw (SI) based on rock brittleness index in rock sawing process. A variety of rocks, including carbonate and granite, were cut by a fully instrumented laboratory-sawing rig with two different types of circular diamond saws. Laboratory tests were performed at different depths of cut and feed rates. Multiple cu...
