A substitute for blackpowder in which potassium chlorate is used in place of potassium nitrate.
Industry:Mining
A subsurface zone containing water under pressure less than that of the atmosphere, including water held by capillarity, and containing air or gases generally under atmospheric pressure. This zone is limited above by the land surface and below by the water table. It contains vadose water. Compare: zone of capillarity
Industry:Mining
A subsurface zone in which all the interstices are filled with water under pressure greater than that of the atmosphere. This zone is separated from the zone of aeration (above) by the water table.
