DEF

Domaine(s)
  • Travail aux explosifs (Exploitation minière)
CONT

La formule du bouchon en éventail, dérivée du bouchon conique, permet l'emploi de beaucoup plus d'ouvriers parce que, les trous de mine se trouvant dans des plans verticaux perpendiculaires au front, les foreurs ne se gênent pas entre eux. Ce bouchon permet d'autre part des abatages d'une plus grande longueur parce que les premiers coups ne sont plus tirés au centre de la galerie, mais au mur, ce qui laisse beaucoup plus de place disponible pour le forage [...] Le bouchon en éventail est de plus en plus employé pour les travers-bancs à avancement rapide.
