In linguistic morphology and information retrieval, stemming is the process of reducing inflected (or sometimes derived) words to their word stem, base or root form—generally a written word form.

The stem need not be identical to the morphological root of the word; it is usually sufficient that related words map to the same stem, even if this stem is not in itself a valid root.

Current stemming methods involving clay/ plastic blast stems are seldom standalone, and often require the addition of traditional stemming material, usually drill cuttings.

Added to this, many current solutions have drawbacks making them unsuitable for underground operations with gas. In some cases the wrapping material itself poses a fire risk. METAL AND NON-METAL DEEP MINE OPERATORS License No. Name of Mine/Permit No. Bradys Bend Corp. Cass St.
