Travaux de minage souterrain \u00e0 la Chaudanne, entre Montbovon et Ch\u00e2teau-d’Oex , avec TSM \u2013 Travaux Sp\u00e9ciaux et Minage . Ca change de la sp\u00e9l\u00e9ologie, m\u00eame si la sp\u00e9l\u00e9o est une bonne base pour ce genre de travaux.<\/p>\n
La technique des faisceaux (allumage non \u00e9lectrique) est utilis\u00e9es pour ce minage d\u00e9licat la ligne de train du MOB passant \u00e0 seulement une vingtaine de m\u00e8tres du tir. Les charges sont mise \u00e0 feu avec plus d’une dizaine de degr\u00e9s de retards diff\u00e9rents pour limiter les \u00e9brenlements. Un minage parfait sans aucune projection et des \u00e9branlements bien en-dessous des normes strictes impos\u00e9es par la voie de train (des mesures de vibrations sont effectu\u00e9es \u00e0 proximit\u00e9). 23 m3 de roche ont \u00e9t\u00e9 min\u00e9s au fond des puits de 3 m\u00e8tres de diam\u00e8tres, soit 62 tonnes !<\/p>\n
Sur un chantier de ce type, un concept de s\u00e9curit\u00e9, incluant une analyse de risques compl\u00e8te, est appliqu\u00e9 avec rigueur. Merci Jacques pour cette mise en pratique du permis de minage !<\/p>\n","protected":false},"excerpt":{"rendered":"
