Clay mineralogy and shale instability: an alternative

A recent review of clay swelling (Anderson et al., 2010) maintained that osmotic swelling of Na-smectites at the interlamellar level was the principal cause of shale instability during drilling operations. Although this mechanism is certainly important, it cannot be a universal cause of shale instability, as many problem shales are non-smectitic.

CAUSES OF LAND SUBSIDENCE

Less common causes include soil swelling and collapsing, groundwater withdrawal, and the dissolution of rock underground. Often several factors contribute to the unstable ground conditions causing sinkholes. There are approximately 23 historic mining sites with underground tunnels identified in the state, according to Thomas.

The inward swelling strain has much greater magnitude than bulk strain,23 and thus, it can be assumed that the coal- adsorbing gas only causes inward swelling strain, but no change in the bulk strain of coal.
