Prediction Method for the Ground Vibration Damage Boundary of Thick and Hard Rock Layer Fracture Type Mine Quakes

Table 1

Prediction of different ground vibration damage boundaries during mining in the longwall 16101 face.

	Vibration response degree	v (mm·s^-1)	r (m)	l (m)
Limestone	Obvious vibration	10	4,172	4,187
	Strong vibration	30	1,218	1,233
	Civilian building damage	50	690	705
Igneous rock	No mine quake and ground vibration damage response
