Natural stone extraction

Project description

Natural stone extraction with explosives is a modern and efficient method of extracting raw materials from the ground. This innovative technique is based on the use of non-explosive explosives, which have been specially developed to enable the controlled and precise fragmentation of rock. When using swelling explosives, chemical reactions create a powerful expansion that breaks up the rock without the negative effects of conventional explosives. This method is not only safer, but also more environmentally friendly and causes less noise and vibration.

Project schedule

The process of quarrying natural stone with swelling explosives is divided into several steps. First, the project is planned, taking into account the geological conditions and the amount of natural stone required. Boreholes are then drilled into the rock. It is important that the borehole diameter is between 25 mm and 45 mm in order to ensure an optimum effect of the swelling explosive. As a rule, the borehole spacing should be ten times the borehole diameter in order to ensure an even distribution of the pressure. After drilling, the swelling explosive is filled into the prepared holes. The mixing ratio is 1.2 liters of water per 5 kg of swelling explosive in order to achieve effective activation of the chemical reactions. After filling the boreholes, a short waiting period follows to allow the reactions to complete before blasting is carried out. This precise procedure ensures that natural stone extraction takes place efficiently and without undesirable side effects.

Drilling information

The correct drilling information is crucial for the success of natural stone extraction with swelling explosives. The choice of borehole diameter and spacing has a direct influence on the effectiveness of the swelling explosive. The borehole diameter should be within the optimum range of 25 mm to 45 mm. In addition, the borehole spacing should generally be 10 x the borehole diameter. These standards are crucial to ensure safety and to achieve uniform fragmentation of the rock.

Consumption

The consumption of swelling explosives is an important aspect of natural stone quarrying. As a rule, consumption is around 10 kg of swelling explosive per cubic meter of rock. This measure gives companies a clear idea of the resources required and enables efficient planning and cost estimation. The use of non-explosive explosives such as swelling explosives not only reduces overall costs, but also helps to minimize environmental impact.

Time / Costs

Natural stone extraction with swelling explosives offers numerous advantages in terms of time and costs. The precise and controlled application of the swelling explosive enables faster and more efficient crushing of the rock compared to conventional methods. This allows companies to significantly reduce their production times. In addition, the reduction of noise and vibrations leads to less disturbance in the surrounding area, which increases the acceptance of projects by residents and authorities. The costs for natural stone extraction with swelling explosives vary depending on the scope of the project and the specific geological conditions. However, through precise planning and optimized material consumption, companies can benefit from the cost savings that result from the use of swelling explosives.

Expert opinion

Natural stone quarrying with explosives is an innovative method that offers numerous advantages for companies in the industry. The use of non-explosive explosives enables controlled and safe rock fragmentation that is both environmentally friendly and cost effective. With clear specifications on borehole size, spacing and mixing ratios, the efficiency of this method can be maximized. Natural stone extraction with swelling explosives is therefore a future-oriented solution that meets the requirements of the industry.
