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

Table 3

Villages subsidence prediction for the different mining schemes with grouting.

Scheme	L1; (m)	L2; (m)	Subsidence; (mm)	Slope; (mm· m^-1)	Horizontal strain; (mm· m^-1)	Damage level
1	200	300	300	2.2	-2.0 ~ +1.6	I
2	250	250	280	1.6	-1.6 ~ +1.4	I
3	300	200	250	1.6	-1.6 ~ +0.8	I
4	350	150	250	1.6	-1.6 ~ +0.7	I
5	400	100	250	1.6	-1.6 ~ +0.7	I
6	450	50	250	1.6	-1.6 ~ +0.7	I
7	500	0	250	1.6	-1.6 ~ +0.7	I
