The National Association of Mining History Organisations (NAMHO) was formed in 1979 to promote the interests of mining historians and those organisations which seek to preserve the relics of the mining past of the United Kingdom. There are currently over sixty member organisations which probably represents about 4,000 persons.
NAMHO acts as a national pressure group and a liaison between member organisations. It encourages improvement in research techniques and safety, and devises guidelines and codes of practice on subjects such as collection of minerals at mineral sites, archive research, mine exploration, bat habitats, problems with radon gas underground and the removal of objects from mines and mine sites. NAMHO also organises a biennial conference and in alternate years a national field event.
