Surface Blasting


Surface blasting activities involve determining the volume of rock that is needed to be blasted and the best possible method as to how to achieve this in the safest manner. Burden and Spacing of the holes will need to be adjusted depending on the depth of the holes which need to be drilled as well as the type of blasting needing to take place. Surface blasting activities involve trenching, road cutting, boulder busting in trenches etc.

A qualified blaster will analyze the situation with respect to the rock, which needs to be blasted and determine as to how it must be drilled. Permits for the blasting are then obtained from the SAPS who gives permission for a company to blast in that specific area. The inspector of explosives is then notified of the blast that will be taking place, and told as to the amount of explosives that will be utilized as well as the location of the site and how far away from the drawing magazine the site is. All vehicles that carry explosives must meet the specifications as per the Explosives Act, as well as the box that will carry the necessary explosives. All the necessary safety actions are carried out on the site prior to setting off the explosives

Blast Recording


Certain sites may require a vibrometer to measure the vibrations caused by the explosion – sites may be near to buildings, private property, commuters, roads etc. In this case, Blast It Blasters does have the equipment to perform the recording for specific clients.


Safety Precautions


In some instances, there is the possibility of potential fly rock from shallow trenching foundations or similar activity, which may call for measures to be put in place to curtail this event from happening. In such a case, either blast rubber mats can be placed over the drilled holes or with respect to shallower trenches/cuttings, excavated material in the area can be backfilled over the exposed holes to a height of no more than the depth of the holes drilled and more.

Tunnel blasting involves design of a drilling pattern into the desired area of rock that is to be blasted. These holes are then filled with explosives drawn by the blaster from the explosive magazine and charged to the design in order to achieve the desired blast action. The explosion causes the rock to collapse, which enables the distance of the tunnel to be lengthened.

The circular shape of the tunnel, which is needed for say jacking operations is conducted in such a way that the holes must be drilled so that the collapse of the rock forces the shape to remain in place. The hole depths are calculated and positioned in such a way to achieve the desired affect. It must also be noted that the shape of the tunnel is also affected by the necessary timing of each explosion. The drill and blast process is constantly repeated until the desired length of the tunnel is reached.


Tunnel Blasting


Chemical / Non-explosive Blasting

Some clients with regards to the surrounding infrastructure nearby to the site, as well as specific legislation or sensitive areas often use this method of blasting as to not disturb the local surroundings.

This method involves the drilling of the desired rock to be blasted and charged with a non-explosive cartridge, which is inserted into the rock.

Once the chemicals have been mixed in the correct way and placed into the drill holes, cracking will take place after a certain amount of time.
