In order to investigate the influence of interfacial angel on failure characteristics and mechanism combined coal-rock mass, 35 uniaxial/biaxial compressive simulation tests with 5 different angels samples were conducted by PFC2D software. The following conclusions are drawn: (1) strength cohesion decrease increase angle, which is defined as angle between structure plane exterior normal maximum principal plane, while changes elastic modulus internal friction not obvious; (2) impact energy...
Abstract We investigate the influence of fault roughness on physical damage prior to large laboratory rock failure and evolution local stress field surrounding zone as macroscopic shear slip approaches. To achieve this, we analyze acoustic emission (AE) data from displacement‐driven friction experiments conducted porous sandstone samples containing either a saw‐cut (smooth) or rough fault. Using high‐quality AE‐derived focal mechanisms two tensor inversion approaches–one considering...
Electromagnetic radiation (EMR) can reflect the stress state and deformation level of coal, yet its warning indexes correlated with coal properties roof caving is poorly understood. The laboratory observations EMR effects samples bursting failure in situ investigations process are presented this paper. peak increasing discussed when happens, which provides an explanation to signals positively well loaded. linearly relation also found between intensity uniaxial compressive strength, maximum...
Using UDEC discrete element numerical simulation software and a cosine wave as vibration source, the whole process of rockburst failure propagation attenuation characteristics shock in coal-rock medium were investigated detail based on geological mining conditions 1111(1) working face at Zhuji coal mine. Simultaneously, by changing thickness strength immediate roof overlying seam, roadway properties understood clearly. The presented conclusions can provide some important references to...
