High stress and multi faults lead to rising burst frequency in deep coal mine. Though backfilling mining serves as the most straightforward method for stress-decreasing and burst-preventing, it fails to eliminate coal burst completely. In order to de

Mechanical behavior of the rock in tensile stress environment remains an unresolved problem in the underground mining, where surrounding rocks commonly experience tensile failure. In the present study, tensile failure behavior of three types of sedim
