Conclusions
Modern testing equipment and software allows to
produce and evaluate environmental impact of
mining.
Due to measuring water velocity, flow and discharge
from the mines, test pumping for evaluating
hydraulic conductivity of the rocks, monitoring
ground and air vibration it is possible to analyse
mining impact to environment.
The most easy and useful way is to perform the
measurement in the form of science club that has
been successfully started in Mining department of
Tallinn University of Technology.
