Reference works
In the last 25 years people in our company have done theoretical and practical works at the following area:
- Professional work and improvement
- Special and practiced blasting works planning and execution.
- Planning and execution of special and practised blasting works
- Writing of technical and textbook
- Professional training
- Explosive trade
From the above mentioned activity we would like to stress the importance of next:
1. A technician of our company was working in China. He was a member of a professional team.
They consulted and had worked on the biggest spout out from the mine over the world.
The last decades we had worked on many methods
in the blasting technology for the building industry and deep blasting.
For example: We had worked out a special enviromental blasting technology
and made an expertise for a tunnel blasting 140 m2 under a busy traffic juction with 8 m-s.
It was in Germany in Wuppertal.
2. We have mention a remarkable blasting at a power station.
This was a special, low frequency and enviromental blasting technology.
There we had pulled down a bunker of ferroconcrete (150 m3) by blasting next to an active factory.
There passed along under the pressure of piping.
The distance was 30-50 cm from the thickness of wall and floor.
(the thicness of wall was 1 m and the thicness of floor was 2,4 m of the bunker)
The distance from an active turbine of ferroconcrate foundation was not more than 3 metres.
That the affect of blasting vibration the main of turfine axle had to stay under 50 mikron.
The works of blasting and denvalition we had done without any abnormality.
Meantime the factory was working continuously.
Blasting of building in Budapest near a shopping centre
Housebreaking by blasting in a very busy and a built in area is one of most difficult work.
This is rejected mostly in the beginning of work because of the damaging seismic affect of blasts on building.
By choosing of the right blasting technology we can determine the seismic loadibility optimally.
During blasting the blasting affects to the enviroment consist of many single and extending explosion.
This effect to the enviroment in case of expert planning is negligible.
