摘要:

三山岛金矿三面入海,是我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的矿床,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,防治水效果直接影响矿山的安全生产,因此,井下超前探水显得尤为重要。目前,探水方法主要有钻探和物探2种,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,其优点是探水距离远,施工进度快。钻探法比较直接,效果好,但施工较慢。通过在三山岛金矿的对比实践应用,得出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。

Abstract:

Sanshandao gold deposit is the first seabed mining in China,which has three sides connected to the sea,with ore bodies hosted in the below sea level.The deposit is mainly fractured aquifer water-filling,with moderately complex hydrogeological conditions,threatened by the overlying surface water bodies (sea water) ,so the effect of water prevention has directly impact on production safety,therefore,advanced water exploration becomes essential.Drilling and geophysical exploration are the mainly two water exploring methods.The latter determines that there is gushing water section within the strata or not according to the difference of resistivity in different substances,and has the advantage of long exploring distance and faster construction progress.Drilling method is more directly and more effectively,but with slower construction progress.By contrast the practical application in Sanshandao gold mine,we come to the conclusion that geophysical exploration obtained a large economic benefits and security benefits.

Key words: Drilling, Geophysical, Seabed mining, Waterproof, Application effect
