Blast mining is a technique used to extract minerals and resources from the earth by using explosives. This method involves drilling holes into the rock, filling them with explosives, and detonating them to break the rock apart. The resulting fragments can then be collected and processed for valuable materials, such as coal or metal ores. This mining method is often employed in areas where traditional mining techniques are less effective. It allows for the efficient removal of large volumes of material, making it a popular choice in the mining industry. However, it also requires careful planning and safety measures to minimize risks to workers and the environment.
