四川石棉矿的矿床大部分高出于当地地平线以上800～1100米,山形坡度达30～40°。含矿带由厚度达数百米的蛇纹岩组成,围岩顶盘凝灰岩,底盘辉绿岩。该矿一向采用沿矿体走向的阶段平峒开拓法。最低阶段平峒标高1248米,最高阶段平峒标高1563米,阶段高度不等(26～69米),各阶段平峒均是独立的运输通道。在每个阶段坑口产设有小型简易粗选点,粗选后的矿石,经架空索道运至山下精选厂。
Most of the asbestos deposit in Sichuan is 800 ~ 1100 meters above the local horizon and the slope of the mountain reaches 30 ~ 40 °. The ore-bearing zone is composed of serpentinite with a thickness of several hundred meters, the top rock tuff of surrounding rock and the diabase of the chassis. The mine has been used along the ore body to the stage of development of flat 峒 law. The lowest level of flat 峒 elevation of 1248 meters, the highest level of flat 峒 elevation of 1563 meters, the stage height ranging from (26 to 69 meters), all stages of flat 峒 are independent transport corridors. Hang Hau at each stage with a small rough crude selection point, rougher ore, the ropeway transported to the Yamashita Refinery.
