Charles Storoni, retired mine surveyor
Charles Storoni first trained at the „Handwierker Schoul“, the state professional school, and then at the „Ecole des mines“ in Esch-Sur-Alzette to become a mine surveyor. At that time, this four-year training included two days of theoretical lessons and a lot of practice in the field.
He then became a surveyor for the factory in Rodange and thus worked around the Fond-de-Gras, in the underground tunnels and also in open-cast mining. He finished his career at the factory in Differdange.
What is the profession of surveyor?
The surveyor is the architect of the underground. In fact, he determines the direction and the height at which the galleries are dug. He actively measures and monitors the progress of the work in the mine, plans and draws the future routes. The surveyor also takes samples to examine the ore layers for the content of the various components.
The profession developed after the Second World War. Before then, many mines had not employed surveyors or had only occasionally called on such a specialist. Without them, however, the mines were poorly exploited. This is because the miners dug a little indiscriminately and only extracted part of the potential.
Advantage of opencast mining
Opencast mining has several advantages. It is relatively inexpensive and allows for lower cost prices. Besides the advantage of lower costs, it also offers the advantage of greater safety for workers. Workers can work in the open air without taking certain risks that miners are exposed to underground. Nevertheless, accidents due to landslides have occurred repeatedly in opencast mining, especially after heavy storms or during frost.
Many thanks to Charles Storoni for his valuable contribution.
