| description | In opencast coal mines, a series of sandstones, shales and coal usually accompany a coal seam
that formed coal measures. Due to rapid development in UK, opencast coal mines are reinstated
with substantial depths of fill materials to provide land for the development. Therefore, it
is crucial to understand the durability and compression characteristics for most engineering
projects involving this material. Laboratory experiments such as slaking immersion test, slaking
index test, oedometer test and Rowe cell consolidation test were carried out on samples taken
from three different sites in UK to simulate changes of moisture content of the material. Collapse
compressions upon introduction of water were exhibited by all three types of coal measures
rocks up to 15% to 30%. The large strains are believed to be due to the wetting of the outer
part of the particles acting as a lubricant, causing the wetted particles to slide past one another
allowing the soil to collapse. It is concluded that the susceptibility of each coal measures rocks
to rapid deterioration in the presence of water are diverse dependent upon its proportion of clay
and silt size. |
