What does rock drilling cost?
Rock drilling is often necessary before the actual blasting can be carried out, or in connection with drilling for water, drainage, gas, cables or other purposes. The price of rock drilling depends on the depth and diameter of the holes to be drilled, as well as the type of rock and availability. It is difficult to estimate a specific price for rock drilling, as there are so many factors that can influence the price in one direction or another.
The price for drilling holes with a diameter of 32-51 mm and a depth of 0.5-3 meters usually costs between NOK 250 and 500 per meter. The price increases for deeper holes and larger diameters. Drilling holes with a depth of 10-20 meters and a diameter of 76-127 mm can cost from NOK 500 to 1,200 per meter. You also need to factor in some form of start-up cost to cover planning, surveying, and transportation of equipment and materials.
How much does blasting cost?
The price of blasting depends on the size of the area, type of rock and availability. You often have to pay a rigging cost, and for transportation of the drill and necessary equipment. If the blasting is to be carried out in a residential area, you may need to set up surveillance of neighboring buildings using cameras and sensors. Then there is the cost of the blasting itself. The price increases in line with the number of times you need to blast. For example, it’s more expensive to blast three times than to blast a lot at once.
The average price for blasting rock and stone is around NOK 5,000 per cubic meter but varies from NOK 2,500 to NOK 10,000 per cubic meter. The average price for blasting work in connection with a single-family plot is between NOK 100,000-300,000. For smaller projects, such as the removal of individual stones or blasting for a garage, the price is usually in the region of NOK 30,000 to 60,000.
Larger projects and demanding rock conditions can easily exceed NOK 500,000. That’s why it’s important to obtain a specific quote from a contractor who can assess the actual conditions on the site.
What affects the price?
- The size of the area to be blasted
- Type of rock and degree of difficulty
- Accessibility and access to the area
- Amount of rock to be removed
- Need for securing and cleaning after blasting
- Distance to the nearest settlement
- Local conditions that require special considerations or measures
- Need for drilling before blasting
- The contractor’s experience, expertise and capacity
- Season and market situation
Is blasting subject to an application?
Yes, blasting requires an application in most cases. According to the regulations on explosive goods, all blasting must be reported to the police before the work starts. The developer must submit a form with information about the time, location, amount of explosives, purpose of the blasting, who will carry out the work, plans for vibration measurements and any closures. Permission must also be obtained from the municipality and neighbors. Without an application and approval, sanctions and fines may be imposed. In addition, failure to apply can have consequences for insurance and compensation should something happen. It is therefore important to ensure that the contractor has all the necessary permits in order before starting work.
There are also strict requirements for who is allowed to carry out blasting work. Both the company and the responsible rock blaster must have central approval from the Directorate for Building Quality to undertake blasting assignments. This includes requirements for relevant education, practice and safety courses.
The requirements are extensive and detailed to ensure the safety of the personnel carrying out the blasting work and the surrounding area. Blasting is associated with great risk, and even small errors can have serious consequences. It is therefore very important that the work is only carried out by qualified personnel with the necessary approvals.
Who should be notified when blasting?
When blasting, it is important that all affected parties are notified in good time before the work starts. This includes residents, landowners, licensees and relevant public authorities that may be affected by the blasting. The company carrying out the blasting work is responsible for informing and notifying in accordance with a separate notification plan. This plan must be part of the overall blasting plan and must be available before the work begins.
The police must always be notified of blasting work, for both public order and safety reasons. It is sufficient for the police to be informed that blasting is taking place during a given period, unless there are special circumstances such as road closures or other measures that require closer dialog. In addition to directly affected parties, a specific assessment must be made of who may experience negative consequences such as noise, dust, vibrations or ejections. The throw length table can be used as a starting point for defining who is affected.
Notification can be made in writing, verbally, by post, posters, advertisements, telephone, e-mail or SMS. In some cases, it may also be appropriate to arrange separate information meetings. The most important thing is that all those affected receive good and uniform information adapted to their needs.
Blasting rock near houses
If you’re going to blast rock close to buildings, thorough planning and notification are particularly important. The vibrations from the blast can cause damage to buildings, especially older houses without solid foundations. Before the work starts, a crack and condition check should be carried out on nearby buildings.
It may also be appropriate to place vibration meters to ensure that the limit values are complied with. Blasting must be adapted to local conditions and carried out gently, preferably with smaller charges. Good communication with neighbors is crucial to avoid conflicts and concerns.
Hydraulic blasting
Hydraulic blasting is a gentle and quiet method of crushing rock and stone without the use of explosives. The method is well-suited to densely populated areas or close to buildings, as it does not cause vibrations or noise. In hydraulic blasting, a special cement is pumped under high pressure into boreholes in the rock.
As the cement expands, it crushes the rock. This method is more expensive than conventional blasting and is therefore primarily used where environmental considerations weigh heavily.
