Mining Matters is a charitable organization dedicated to bringing knowledge and awareness about Canada''s geology and mineral resources to students, educators and the public. The organization provides current information about rocks, minerals, metals, mining and the diverse career opportunities available in the minerals industry.
Mechanically anchored rockbolts are probably the oldest form of rock reinforcement used in underground mining and are still the most common form of rock reinforcement used in Canadian mines. Provided that the rock is hard enough to provide a good grip for the anchor, an expansion shell anchor which is well seated
Underground soft rock mining is a group of underground mining techniques used to extract coal, oil shale, potash and other minerals or geological materials from sedimentary (quot;softquot;) rocks. Because deposits in sedimentary rocks are commonly layered and relatively less hard, the mining methods used differ from those used to mine deposits in igneous or metamorphic rocks (see Underground mining
The Underground Hard Rock Miner Common Core Program is designed to cover the following areas of competency required in the Ministry of Training, Colleges and Universities (MTCU) Certification Program 770010. U0000 Follow Surface and Underground Induction Procedures U0001 Perform General Inspections U0002 Scale Loose Rock
Underground mining (soft rock) refers to a group of underground mining techniques used to extract coal, oil shale, potash and other minerals or geological materials from sedimentary (quot;softquot;) rocks.

Common Core training provides mandatory entrylevel training for new workers entering specific mine work environments. For example the Underground Hard Rock Miner Program #770010 consists of four mandatory Common Core and 75 Specialty Modules (which are taken as required). The four Common Core modules cover the following competencies:
Mining Common Core Underground Hard Rock Miner 770010* Specialty Skills Modules Underground Hard Rock Miner 770010 Common Core First Line Production Supervisor Underground Hard Rock Miner 770120* Common Core for Basic Underground Soft Rock Miner 770130* Specialty Skills Modules Underground Soft Rock Miner 770130 Common Core for
Underground Soft Rock Miner Common Core and in the Specialty Modules that pertain to their work. Workers engaged in mining excludes workers registered and accredited under the program #770130. These modular training programs are designed to ensure minimum performance standards
#0183;#32;Most underground mining methods have prohibitively high operating costs, which only allow high grade deposits to be mined. Block caving has a high production rate, which means high capital costs at the start of the project but relatively low operating costs.
