Drilling and Blasting Technical Aspects of Mining

Drilling. Most blasting in mines involves charging explosives into holes drilled in rock. The entrance or mouth of a drill hole is called the collar and the end is the toe. Drilling is still carried out in some cases, in the ASM sector, by hand, using a hammer and chisel. This is obviously tedious and slow, especially in hard-rock mining

Evolution Mining puts its Red Lake “turnaround strategy” in

The Red Lake operation has a 13-year mine life and, according to Evolution, there is “outstanding exploration potential” to grow the resource base in a geological environment that they are quite familiar with.

Best Drill Interceptions In The Metals Mining Sector For The

Evolution Mining has been delivering very good drill results from Cowal, and it plans to boost the mine& 39;s production to more than 300,000 ounces of gold per year.

3 Technologies in Exploration, Mining, and Processing

The three major components of mining exploration, mining, and processing overlap somewhat. After a mineral deposit has been identified through exploration, the industry must make a considerable investment in mine development before production begins.

Among underground coal miners, hearing loss remains one of the most common occupational illnesses. To address this problem, the U.S. National Institute for Occupational Safety and Health Office of Mine Safety and Health Research NIOSH OMSHR conducts research to reduce the noise emission of underground coal mining equipment, an example of which is the roof bolting machine.

How Can Drill and Blast Operations Make Mining More Sustainable

“A mine site is full of orebody knowledge, evolution of rock, geochemistry, mineralogy, hyperspectral, geometallurgy and more. All this data collected is challenging to incorporate into a consistent spatial model: geostatistics can struggle with large amounts of disparate data types.
