摘要：三山岛金矿三面入海,是全国第一个海底采矿矿山,矿体均赋存于海平面以下,是以裂隙含水层充水为主矿床,水文地质条件中等复杂,并且受到上覆地表水体（海水）充水的威胁,防治水好坏直接影响矿山的安全生产,因此,井下超前探水变得尤为重要.目前,探水方法主要有钻探和物探两种方法,物探是利用不同物质的电阻率不同,确定岩层内有没有涌水地段.钻探法比较直接,效果好,但施工较慢,物探技术优点是探水距离远,施工进度快.通过在我矿的对比实践应用,我们得出结论,坑道的物探法超前探水应用不但具有较大的经济效益,还具有巨大的时间效益和安全效益.

Three mountain island gold three surface into the sea, is the first submarine mine mining, ore body is hosted in sea level, is the fracture aquifer water is given priority to deposit, hydrogeological conditions, and secondary complicated by overlying surface water (salt) water threat, a direct impact on the prevention and control of water safety in mine production, therefore, downhole advance ground water is particularly, At present, the ground water method to basically have two kinds of drilling and geophysical prospecting method, geophysical prospecting is the use of different material resistivity is different, sure there were no rock water gushing location. Drilling method is more direct, the effect is good, but the construction is relatively slow, geophysical prospecting technology advantage is ground water of distance and construction progress fast. Through the contrast of WoKuang in practical application, we come to the conclusion that the tunnel geophysical method leading ground water application not only has great economic benefits, but also has great time efficiency and safety benefits. important.
