Stress distribution characteristics in front of the working face.

Observation line	Observation line position	Range of stress increase zone (m)	Stress peak value (MPa)	Distance from stress peak to working face (m)	Stress value in the stability zone (MPa)
1	Near the reused entry	75∼80	9.55	10	7.45
2	In the middle part of the working face	75∼80	8.37	10	3.35
3	Near the headgate of S12013	45∼50	7.09	10	3.90
