| The research and developement project "REKULT" |
|
| |
|
| This research and developement project (4/1997 - 3/2000)
was launched in order to enable dead ground dumps to be efficiently
recultivated at low cost, aimed at developing a business segment
for the renaturing and recultivation of landscape following mining
activities. |
|
| |
|
| Efforts were made to formulate standards for the evaluation
of the initial situation as well as for the definition of practical,
achievable targets through the interdisciplinary synergy of mining
engineering, mining industry, geology, greening and planting technology.
On this basis, suitable technical and biological measures were worked
out. |

|
More than 200 trial plots were installed in REKULT,
the square dimension comes to 600 000 square metres. All these plots
were studied interdisciplinarely. The results were compiled in a
database, that now allows analyses and comparison of data as well
as their interdependencies. This data also were supplimented with
facts from external areas.

|
| We tried to reduce the influence of unfavourable general
conditions and succeeded in creating a new method, called
the "thick-layer-process". This method is a hydroseeding
variant owing to which the germination results, growth behavior,
clover establishment and biomass formation on the Styrian Erzberg
mountain have been essentially improved. Hydrogeological investigations
prove that leaching of nutrients has occurred to a harmless extent
and for a short time only, so the process can be described as being
ecologically compatible. |

|
| Our new method was presented at the World Mining
Congress in New Delhi in November 2003. |
