Method to Calculate Mining-Induced Fracture Based on the Movement and Deformation of Overburden Strata

Table 1

Data collected to set the parameters of the probability integral function.

Position of major cross section	Subsidence coefficient q0	The tangent of the main influence angle tanβ		Inflection point offset S0 (m)		Mining influence transmission angle θ0
		Downhill	Uphill	Downhill s1	Uphill s2
Dip	0.80	2.43	2.30	0.14H1	0.13H2	78.75°
Strike	0.80	1.88	0.15H0

H₁ and H₂ are the buried depth of coal seam at the boundary of downhill and uphill in dip direction.
