Crushing and splitting stones with BETONAMIT®

Project description

Stone crushing is a common concern in the construction industry, landscaping and demolition work. Traditionally, mechanical methods or explosive blasting techniques are used for this purpose. However, the use of swelling explosives offers an efficient and safe alternative for crushing stones. Swelling concrete, also known as blasting concrete or swelling agent, makes it possible to work without strong vibrations and noise emissions. This makes it particularly attractive for use in densely populated or sensitive environments. Swelling explosives work by controlled expansion, which means they can be used selectively to crush rocks precisely without endangering surrounding structures. The process is not only more environmentally friendly, but also more economical as it reduces deployment time and associated costs. On this page you will learn how the crushing of stones with swelling explosives works, which procedures are required and which safety regulations must be observed.

Project schedule

The process of crushing stones with swelling explosives is well structured and can be divided into several steps. First of all, careful planning is required to analyze the nature of the stones and the geological conditions of the site. This information is crucial for determining the correct borehole diameters and spacing. For stone crushing, the borehole diameter should be between 25 mm and 45 mm. The distances between the boreholes should be selected so that they are generally ten times the diameter of the borehole. In the next step, the drill holes are drilled into the stones. It is important to ensure that the minimum drill hole depth is five times the diameter. This ensures optimum pressure distribution during the crushing process. The swelling explosive is then filled into the prepared holes. The recommended mixing ratio is 1.2 liters of water per 5 kg of swelling explosive to achieve the desired expansion. After filling the drill holes, an activation time takes place during which the pressure in the stone is built up. This controlled expansion results in the stones being broken up in a targeted manner without the typical dangers and inconveniences of conventional blasting methods. This ensures both efficiency and safety throughout the entire process.

Drilling information

The correct drilling information is a key aspect when crushing stones with swelling explosives. The choice of the correct drill hole diameter has a direct influence on the effectiveness of the crushing process. The recommended diameters of 25 mm to 45 mm offer the necessary flexibility to process different types and sizes of stone efficiently. The larger the diameter, the greater the expansion force of the swelling explosive. The material consumption per meter of drill hole is also important and varies depending on the diameter: 25 mm: 0.9 kg/m 30 mm: 1.24 kg/m 35 mm: 1.68 kg/m 40 mm: 2.2 kg/m 45 mm: 2.78 kg/m This information is crucial for planning the material requirements and helps to increase the efficiency of the project. In addition, the distance between the drill holes is important: smaller distances lead to faster crack formation, which results in faster crushing and makes it easier to handle the fragments.

Consumption

The consumption of swelling explosives when crushing stones is an important aspect of project planning. On average, the consumption is around 10 kg of explosives per cubic meter of crushed material. This figure is an important indicator of the material costs and the overall cost-effectiveness of the project. The exact calculation of the requirement depends on the specific conditions of the site and the selected borehole diameters. Precise planning of material usage not only contributes to the efficiency of the project, but also reduces the risk of unexpected costs and delays. Excessive use of materials can unnecessarily increase costs, while insufficient use can delay the project.

Time / Costs

The time and cost factors for crushing stones with swelling explosives are significantly more advantageous compared to traditional methods. The explosion-free technology enables work to be carried out quickly, saving time and resources. The reduction of noise and vibrations is particularly important in urban areas, where compliance with noise regulations is often a challenge. The overall duration of the crushing process depends on various factors, including the size and type of stones as well as the complexity of the work. However, careful planning and the targeted use of swelling explosives can ensure efficient execution. This not only leads to greater customer satisfaction, but also to cost savings, which are of great importance in the construction industry.
