Calculation of Subsidence due to Longwall Mining with Overburden Grouting and Its Application

Table 2

Ground and villages deformation prediction without grouting.

Mining directly	Subsidence; (mm)	Slope; (mm· m^−1)	Horizontal strain; (mm· m^−1)	Curvature; (mm· m^−2)	Horizontal displacement; (mm)	Damage level
Surface	−2100	10	−11~5	-0.14	1000	IV
Villages	-1600	8	-9~3	0.08	600	IV
