The drill and blast method is a widely used technique in mining operations, particularly in hard rock mining. This process involves two key components: drilling holes into the rock formation and subsequently blasting the rock to facilitate its fragmentation. Drill patterns are meticulously designed to optimise the blasting process, considering factors like rock type, size, and desired fragmentation. The drilling phase utilises specialised equipment to bore holes into the rock, where explosives a

Longtime UGM member Scott K. Teaches us today about coal mine explosions! Scott is a chemistry teacher at a local high school and brings these lessons into the classroom to explain to students some of the dangers of gasses in coal mines. Over the next few weeks we will be sharing some of his educational demonstration videos on the subject. | Underground Miners

Blasting in mining is a critical method used to extract valuable materials from rock formations. It involves the use of explosives to break up large volumes of rock, making it easier to transport and process. The process begins by drilling holes into the rock, which are then loaded with explosives. When detonated, the explosives create fractures in the rock, allowing the material to be extracted more efficiently. The principles of blasting in mining and tunnelling are quite similar, as both rely
