海底矿产是海底沉积物和海底岩层中的矿产的统称。表层沉积矿产，在滨海有各种金属砂矿和非金属材料；在陆架区有海绿石、磷灰石等矿产和建筑材料；在深海区有铁锰结核和多金属泥。基岩中的矿产主要有铁、煤、硫等，主要分布在大陆架。迄今在浅海区发现和开采的矿产已达数十种。
随着陆地矿产资源的日趋减少，开发国际海底矿产资源是大势所趋。
With the decrease of mineral resources on land, the general trend is exploiting them on international deep sea bed.
但也存在不少限制因素，如深水区离岸较远，海底矿产勘探程度低，自然灾害较多等。
But there are also some restrictive factors, such as the deepwater area is far from the coastline, the prospecting level of submarine mineral resources is low and coastal hazards are serious.
露天开采海滨砂矿和从岸上打井开采海底矿产资源，必须采取有效措施，防止污染海洋环境。
In conducting coastal open air placer mining or shore-based well drilling to exploit seabed mineral resources, effective measures must be taken to prevent pollution to the Marine environment.
