Gisera examines Hydraulic Fracturing Impacts on Air Quality, Soils, Groundwater and Waterways

A comprehensive three-year scientific study into the air, water and soil impacts of hydraulic fracturing in Queensland has found little to no impacts on air quality, soils, groundwater and waterways.

The study also found current water treatment technology used for treating water produced from coal seam gas wells is effective in removing hydraulic fracturing chemicals and naturally occurring (geogenic) chemicals to within relevant water quality guidelines.

Mining: HÖRMANN enters the Brazilian Market with its outdoor Warning Systems


Vallourec installs a modern outdoor warning system with electronic sirens from the German manufacturer in the iron ore mine of Pau Branco near the Brazilian town of Brumadinho to protect the population from deadly mudslides or tidal waves.

 

The Brazilian mine operator Vallourec has equipped its iron ore mine near the Brazilian town Brumadinho with a modern outdoor siren warning system from HÖRMANN Warnsysteme GmbH. The electronic sirens are designed to warn employees and the population in good time of dangers such as a possible dam breach. In January 2019, an accident in another mine in this area caused hundreds of people to die in a mudslide. The warning system is said to have failed. For this reason, Vallourec decided to use the electronic sirens from HÖRMANN Warnsysteme, which are installed in numerous countries around the world and known to be extremely reliable. For the German manufacturer, this was the first installation in Brazil.

The town of Brumadinho in the Brazilian region of Belo Horizonte became sadly famous in early 2019 when the dam of an iron ore mine burst and the mudslide killed several hundred people. In this area, which is one of the main iron ore mining areas in Brazil, many dams of various mining companies are located. They are generally considered to be risky, and a dam breach can never be completely ruled out, even with high safety standards. In the case of this accident, it was also reported that the warning system had failed.

The Vallourec steel group also operates an iron ore mine in this sector. In order to meet its responsibility for its employees and the local population, it was decided to install a modern, reliable siren system "Made in Germany". This was the first project in Brazil for the German manufacturer HÖRMANN Warnsysteme. Together with its partners ELMEC Comércio e Indústria Ltda and EKM do Brasil, based in Belo Horizonte, the company planned an outdoor warning system with electronic sirens that would warn both employees and the population in the endangered locations in good time in the event of a possible disaster.

HÖRMANN Warnsysteme based in Kirchseeon near Munich is the pioneer in the development and production of electronic sirens. In the last 60 years, more than 60,000 sirens and siren warning systems have been installed worldwide. These sirens reliably warn the population in cities, communities, but also in mining regions or in coastal areas in the event of disasters, e.g. tsunamis, tidal waves or toxic fumes due to incidents. This means that HÖRMANN Warnsysteme can be considered as the market leader. The company can already point to several installations in South America, although Brazil has so far been a blank spot on the map. With the order from Vallourec, the company has now succeeded in entering the Brazilian market.

The installation was preceded by extensive planning in combination with sound propagation analyses. This must ensure that all affected regions are reliably warned in the event of an emergency. Three ECN-D electronic sirens were then installed in the working area of the mine and in two villages that would be affected by a flood wave or mudslide in the event of a dam burst. The control center is located in the company's main control room. It consists of a communication unit to the sirens, to which a PC is connected. The operation and status monitoring of the sirens is done by HÖRMANNs own siren control. For security reasons, a backup control center was also set up to ensure a redundant operation of the sirens. The sirens do not only warn with an alarm tone. They also can be used for announcements and propagation of voice messages. Communication between control centre and electronic sirens is established by a specially installed digital radio network. The mast installation was developed by local partners at great expense in terms of durability and protection against vandalism, following HÖRMANN's recommendation. The electronic sirens are operated only by batteries which are charged by solar panels. In addition, a generator can be connected in order to maintain operational readiness even under extremely unfavorable weather conditions.

"Our partners ELMEC and EKM do Brasil have done an excellent job and installed the sirens in our sense and according to our quality standards. We are convinced that Vallourec is well equipped in case of an emergency with this siren warning system", says Dipl. Ing. Matthias Müllner, one of the two managing directors of HÖRMANN Warnsysteme, with conviction. The mine operators in the area probably see it the same way. Two further HÖRMANN systems, each with four sirens, were installed nearby shortly after the first installation at Vallourec. "The area around Brumadinho is the centre of iron ore mining in Brazil. Reliable siren warning systems are indispensable to ensure that disasters such as those occurring at the beginning of 2019 and even as early as 2015, no longer lead to so many fatalities," adds his co-managing director, Dipl. Ing. (FH) Johannes Antoni. "We are therefore pleased to have ELMEC and EKM as proven partners with high technical know-how and a great sense of responsibility in Brazil".
