gas-logged strata
Rock formations, usually in coal mines, that contain a relatively high proportion of methane. In descensional ventilation, the buoyancy pressure of the methane opposes the ventilating pressure, with a tendency for cavities to contain combustible gases of high concentration. The same may apply to waste cavities with no natural exit to the return.
