What is Blast Hole Drilling? That is the first question that comes into your mind when you hear this term; it is a mining technique where the miners drill a hole into the rock’s surface, then fill it with explosive materials and detonate it. It has to be done this way to create cracks in the inner surface of the rock and its surroundings to make it easy for conducting further drilling and conduct other mining activities. This mining method is not used for any different mining process; it is useful where the mining company needs to explore the mineral composition of the demarcated area before they become committed to conducting the whole mining process. To make the method a success, the following things should be considered:

Conduct a survey

Before you start the whole process, you need first to survey the area, clearly investigate the site to ensure that you make better decisions regarding the hole size or diameter, the type and design of drills you will use, among other factors. When you conduct a site survey and understand the nature of the rock, the soil, the minerals available will give you a better lead on how you will conduct the process and the requirements.

Create drill patterns and blast the hole

After the surveyor has found the perfect way to conduct the whole process, the projector manager’s role gets in, and they draw the drilling pattern that will guide the miners. The drilling process begins, the Blast Hole Drilling can be bought or hired; this depends on what the mining company can afford. Once the devices are on the site, the whole process begins; the survey conducted guides the driller on how wide and deep the hole should be.

Break the rock

When the holes are drilled, the rocks need to be cracked, and this happens where the hole is filled with explosives to break the rock. The study and survey were conducted to guide the type and amount of explosives used in the process; once they are packed, a remote is used to detonate the explosives so they can break the rock.

Cleaning

Once the explosives have been detonated and the rock cracked to give the requirements, the tunnel needs to be cleaned of the debris that accumulates or forms after the process. This is done to ensure that it remains safe, and even when the mineral extraction process begins, nothing is put at risk.
