Abstract

Underground coal gasification (UCG), an unconventional technique of coal utilization, is associated with large-scale firing of rocks adjacent to the coal seam. A significant fraction of these rocks are argillaceous and have a composition comparable to mixes of raw material utilized in brickmaking, and in the manufacturing of lightweight aggregates which employes a bloating and expansion fabrication mechanism.
