蛇山矿于1981年开始采矿,矿床的采矿地质条件复杂,矿体呈孤立的扁豆状,厚度多变,介于2～25米之间,时而变厚,时而变薄。埋藏深度自地表以下为40～350米。矿体的直接围岩为泥板岩、石灰岩、凝灰石英斑岩,其特点是强度低,普氏硬度系数f=4～6。矿体的水文地质条件十分复杂,在矿体上部为一河谷的饱含水的砾岩。采矿巷道的涌水量为210～2670米~3/小时。
Snake Hill mine began mining in 1981, the geological conditions of mining deposits complex ore body was isolated lentils, thickness varied between 2 to 25 meters, sometimes thickening, and sometimes thinning. Buried depth below the surface of 40 to 350 meters. The direct surrounding rocks of the ore body are mudstone, limestone and tuffite quartz porphyry, which are characterized by low strength and Platts hardness coefficient f = 4-6. The hydrogeological conditions of the ore body are very complicated. The upper part of the ore body is a water-saturated conglomerate of a river valley. The gushing water of mining roadway is 210 ~ 2670m ~ 3 / h.
