Why Do You Need To Use Hole Savers?

 

Blasting and drilling operations form the backbone of the mining industry. Once drilled, the holes must be clear from debris as redrilling requires significant extra work. Hole Savers help maintain the holes' integrity while preventing the ingress of foreign materials.

 

Keep your hole clear with blow moulded FSP hole savers that are highly durable and can be used at any mining site. Available in many colours, they help highlight the drilled holes while keeping the debris out.

 

Why Do You Need To Use Hole Savers? Don't let your drilling operations go to waste. During mining operations, the holes can be deemed ineffective for many reasons.

 

Hole savers have become a vital element in the mining industry. What are the benefits of using hole savers?
Minimises the requirement of redrilling operations
Minimises collar fallback incidents
Helps retain the drilled depth
Improves the total blast quality
Ensures holes remain open even after nearby blast patterns
Protects explosives hoses during loading
Reduces the likelihood of lead damage
Improves the explosives column quality
Acts as a visual warning for drilled holes
Reusable device

Blast Hole Cover

Drill hole savers, also known as blast hole plugs or hole saver cones, are used in mining operations and other drilling and blasting applications to keep holes clear of debris and maintain their integrity:

 

Blast block preparation
After drilling blastholes, cones are inserted to keep debris out and maintain the hole collar's integrity. Before priming and charging, the cones are removed temporarily, then reinserted once the process is complete. The cones remain in the hole until stemming, preventing debris and collar collapses.

 

Stabilizing holes
Hole savers can help stabilize holes at blasting sites and prevent harmful particles from entering the drill or bore holes.

 

Highlighting holes
Hole savers can make drilled holes easier to identify on-site by coming in a variety of colors.

 

Reducing regrind and dust
Using hole savers can reduce the amount of regrind and respirable dust on a site.
Hole savers can also help keep holes clear for re-drilling and prevent explosive desensitization by water.

 

The Basics About Blast Hole Drilling

 

Blast hole drilling is traditionally used wherever the mining company wants to explore the mineral composition or potential mineral yield of the area demarcated for their mining interests.
Blast holes are thus a fundamental step in the exploratory mining process, and can be employed in both surface mining operations and underground mining operations to varying degrees with varying effects or results.
Blast hole drilling can also be employed in quarrying endeavors.

 

Step 1 – Surveying the location
Before the blast hole drilling can begin, the proposed site needs to be inspected, and certain decisions need to be made with regards to the hole size/diameter, the type of drill or drills that will be required, etc.
These decisions will be based on the findings of the initial site survey.

The site survey will analyse the nature of the proposed mining operation, the nature of the rock, soil, ground, and/or mineral in question, and will impact the road going forward with regard to the blast hole drilling processes.

 

Step 2 – Researching the rock types and formations
Once the surveying processes have provided the surveyors with the raw data, they will turn this data over to researchers, who will then do the necessary research in order to plan effective and safe drilling patterns.

 

Step 3 – Plan drilling patterns
Once the researchers have determined the most effective, efficient, and safest way to proceed, the project manager will take over and draw up the necessary drilling plans.

 

Step 4 – Drilling the blast holes
This is where the actual blast hole drilling starts.
So by now all the machinery will have been procured (hired, acquired, what have you) and will be on-site, and ready to begin drilling the blast holes! The researchers' data will reveal how deep and how wide the diameter of the blast holes should be, as this will depend on the results of the survey.

In other words, on the nature of the mineral being mined, the nature of the surrounding rock/ground/soil etc.

 

Step 5 – Breaking up the rock
Once the blast holes have been drilled they will be packed with explosives. What kind, and the amount of explosives used will have been determined based on the research conducted; just like the size and depth of the blast hole was determined based on the research.
The explosives will then be remote-detonated in order to break up the rock.

 

Step 6 – Clean up process
Just like at a party, once the exciting part is over, somebody has to stay behind and clean up the mess! In underground mining, the tunnel will be cleared of debris, and the tunnel will be suitably reinforced.

 

Otherwise, as in open mine blasting, the rock will be excavated and hauled.

FAQ

Q: What are Hole Savers?

A: Hole Savers are small devices, typically made of metal or plastic, used in construction and demolition to prevent damage to surrounding walls when drilling holes. They are placed over an existing hole or around the drill bit to keep the drill bit centered and to reduce the risk of cracking or chipping the wall during drilling.

Q: How do Hole Savers work?

A: Hole Savers work by guiding the drill bit accurately into the existing hole or by providing a template for drilling new holes. They often have a sharp edge that bites into the surface to keep the drill bit from wandering, ensuring a clean and precise hole.

Q: When are Hole Savers typically used?

A: They are used primarily when working with brick, stone, concrete, and other hard, brittle materials where the risk of cracking is high. They are particularly useful when drilling holes for anchors, bolts, or other fixings.

Q: Are Hole Savers necessary for all drilling jobs?

A: No, Hole Savers are not necessary for every drilling job. They are most beneficial when working with hard, brittle materials or when precision is critical. For softer materials or where the risk of cracking is minimal, a Hole Saver might not be needed.

Q: How do you use a Hole Saver?

A: To use a Hole Saver, first, position it over the intended drilling location. Ensure it is flush with the surface and secure it in place, if necessary. Then, start drilling through the center of the Hole Saver. For existing holes, the Hole Saver will help to guide the drill bit back into the original hole.

Q: Do Hole Savers come in different sizes?

A: Yes, Hole Savers are available in various sizes to accommodate different drill bit diameters. It's important to choose the correct size Hole Saver to match the drill bit being used.

Q: Can Hole Savers be reused?

A: Yes, Hole Savers can typically be reused multiple times. However, their effectiveness may diminish over time as they wear down. It's a good practice to inspect them before each use to ensure they are still in good condition.

Q: How do you clean and maintain Hole Savers?

A: Cleaning Hole Savers typically involves removing any debris or dust after use. They can be wiped clean with a dry cloth. For more stubborn debris, a soft-bristled brush or a mild cleaner can be used. Avoid using harsh chemicals or abrasive tools that could damage the Hole Saver's surface.
