One of the most critical stages of a mining exercise is the blasting stage. Without blasting, it would be virtually impossible to access minerals underneath the earth's surface. Since blasting requires the application of explosives, it is vital to consider several factors before you start moving tonnes of earth.
While the blasting process can be described as a science and art, proper preparation boils down to strategic planning. Therefore, if you are just opening your mining business, understanding the factors to consider before triggering explosives will lead to an effective and efficient exercise. You need to put the following factors into consideration before rigging your mine with explosives.
Electronic Detonators -- With technological advancements, mining explosives continue to change as experts aim for increased efficiency and safety. Over the years, detonators have changed. For instance, electric detonators are playing a significant role in the optimization of mining processes. However, with market dynamics in the mining industry changing constantly, you want a detonator that will maximize production output but keep operation costs down. Since there is no spark involved in electronic detonation, the possibility of accidental fires is reduced. Additionally, electronic detonators give you the power to control the sequence of explosives so that you have the final say on the outcome of the exercise.
Soil and Substrate -- The soil profile in the mining site does dictate the type of explosives to use. You need to remember that there are different substrates found within a mining site, and some might react aggressively when blasted. To avoid possible accidents and total site damage, make sure that you employ the services of a geologist, since they have the appropriate materials and knowledge to analyze the soil profile of a particular site.
Any underground abnormalities present will be discovered by the experts, which is important, as these have the ability to alter the blast sequence. With knowledge of soil composition, it becomes easier to design the explosion in a way that helps you to achieve the desired results.
The Amount of Ground Vibration -- When mining explosives are detonated, there is some vibration on the ground right after the blast. It is important to note that the explosion should not affect areas that are not targeted by the explosion, which means keeping the vibrations at minimal. One way you can avoid excessive ground vibrations is by pre-splitting the rocks to be blasted before rigging them with explosives. The number of explosives needed to break pre-split rocks is limited, which ensures that vibrations are minimized.
