NATIONAL COAL BOARD COLLIERY SHALES - SOME TECHNICAL AND ENVIRONMENTAL CONSIDERATIONS IN THEIR DEVELOPMENT AND USE

"Colliery shale" which is a general term describing minerals associated with coal consists of clay minerals (50-80 percent), pyrite (0-10 percent) and a residue of quartz. The desirability is indicated for describing the material as minestone and the material from older tips where conbustion has occurred as "burnt shale". Characteristics of these two classes are identified. Current use of colliery shales are many and range from screened burnt shale on running tracks and tennis courts through the range of road uses from fill to land reclamation and sea/river defences. The results of research indicate that stabilized minestone provides a material suitable either as CBGM or as sub-base. Other uses include various hard standing areas such as pathways, car parks, etc., as well as low and medium strength masonry blocks. Work is in progress on the use of heat-treated minestone as an aggregate.
