摘　　要：某矿床16号线矿体水文地质特点为地下水埋深大、承压性低。这类特点决定了该矿床地浸开采的最大困难在于钻孔在成孔后如何洗井和如何使被堵塞恶化的含矿含水层恢复到自然状态,寻找一种适合于地下水埋深大的洗井方法是该矿块开采的关键。The specific feature of the 16th section line ore body of a deposit is deep water table and low confined aquifer.It causes the most trouble for well cleaning during completion and recovering the orebearing aquifer to natural state after it is worsened.It is a key point mining the ore body to search for a suitable way for well cleaning at the deep water table.
