Exfoliated vermiculite is used in mining operations as a compacting material for sealing mine openings in order to preventmethane intrusion into underground mines.

In borehole drilling, exfoliated vermiculite is used as a component in drilling grouts which are needed to compensate the loss of flushing fluids. It is due to the ability of vermiculite to block and seal holes within the drilled borehole.
