Mining is known to be a dangerous profession. Miners welcome anyone who reduces risk. In France a new coal extraction technique has been launched in the Darcy mines.

During the extraction of coal in the traditional technique it is necessary to maintain the gallery to slides. This requires large labor and rigorous maintenance on the one hand. The risk is high and only part of the work is mechanized. Use a plate to brush new techniques.

Coal is attacked at two different heights. There are two brushing machines. One works from below and the other from above. The coal falls to the visible conveyor belt at the bottom and is dragged by the belt.
