| Abstract: | reak forms and break reasons of top plate of tunnel beneath another tunnel with short distance are analyzed. The reliability of using rock bolting technique to support such tunnel is discussed. The experience of successful application of rock bolting technique in Yian Coal Mine can be taken for reference by similar mines. |
