Seabed Mining (SBM) is a growing industrial field that involves extracting submerged minerals and deposits from the sea floor. To date, mining for sand, tin and diamonds has been generally limited to shallow coastal waters. Seabed Mining (SBM) should be distinguished from Deep Sea Mining (DSM) that occurs at a depth of 200 meters and greater.

Geologists in some underground gold mines collect grabsamples from broken ore as a method of grade control. It is often known as muck or broken rock sampling. Generally, the goal of grab sampling is to try and reconcile the mined grade at the ore source to the predicted head grade. Additionally, the samples may be used to verify prior in situ
Block caving mining includes drilling holes underground, beneath the ore body, and using planned blasts to break down the ore and the rocks. Then the mixture of rocks and ore fall with the help of gravity to be transported for processing. Block caving mining often takes place once the production through openpit mining becomes uneconomical.
