Predicting Subsidence over Coal-Gasification Sites
The extent to which earth subsidence may be caused by in situ coal gasification is studied using the method of finite elements. This study takes into account rock failure modes and nonlinearity of rock stiffness. Two models were studied for the site at Hoe Creek, where a coal seam is overlain and underlain by interbedded clays and sandstones. These two studies are expected to bracket any subsidence that may occur. Maximum subsidence was 0.06 in. using the stiff model and 3.5 in. using the soft model, neither of which suggests undesirably large subsidence. (ERA citation 02:025762)
