Il existe des dizaines de techniques d\u2019exploitation qui peuvent \u00eatre combin\u00e9es. L\u2019important, c\u2019est que la m\u00e9thode choisie permette \u00e0 la mine d\u2019\u00eatre rentable et s\u00e9curitaire. De fa\u00e7on g\u00e9n\u00e9rale, il existe deux types d\u2019exploitation : sous terre et en surface. Pour choisir entre les deux, nul besoin d\u2019\u00eatre ing\u00e9nieur minier : c\u2019est l\u2019emplacement du gisement qui l\u2019indique.<\/p>\n<\/div>\n<div id=\"comment-se-fait-la-conception-d-une-mine-texte-1\" class=\"fiche-paragraphe-ctn\">\n<p><strong>Une mine souterraine<\/strong><br \/>\nLa seule fa\u00e7on d\u2019acc\u00e9der \u00e0 un gisement profond est de \u00ab foncer \u00bb un puits et d\u2019extraire le minerai par un r\u00e9seau de galeries. Ce type d\u2019exploitation \u00e9tant on\u00e9reux, il faut que le gisement soit assez riche et important pour justifier les co\u00fbts de construction et d\u2019exploitation.<\/p>\n<p><strong>Une mine \u00e0 ciel ouvert<\/strong><br \/>\nLorsqu\u2019un gisement se trouve en surface, on dispose d\u2019une seule option : faire une fosse. Par contre, peu de gisements se pr\u00eatent de fa\u00e7on rentable \u00e0 cette forme d\u2019extraction. Pour qu\u2019on construise un r\u00e9seau de rampes, il faut que le gisement ait une bonne largeur et un bon volume, et qu\u2019il ne soit pas trop recouvert de mort-terrain ni de roche sans valeur.<\/p>\n<p><strong>Les fosses<\/strong><br \/>\nLes fosses se comparent en quelque sorte aux carri\u00e8res.
