    Introduction. Longwall mining induces deformation, fracturing, and bedding plane separations within a large volume in the overburden strata. These effects can release a significant amount of gas from overburden strata, which may find its way into sealed and active areas of the mine if not controlled. Therefore, strata gas control, especially in geologies with high gas amount, is an important
