Compaction characteristics of the caving zone in a longwall goaf: a review

Environmental Earth Sciences, 2019
Broken rock and coal—residual coal, plus material from the immediate roof and overlying strata—fill in the goaf, in an area termed the caving zone. Due to its high porosity and permeability, the caving zone contains gas and water, which may have originated from the mined coal seam, the adjacent unmined coal seam, or from any aquifer or surface river ...
