Theory and numerical simulation equation of gas migration in compressible coalseam with dual-pore have been established.Distribution curves of gas pressure in coalseam and attenuation curves of gas emission out of coal wall or hole have been obtained by computer numerical simulation and similarity theory. There are high gas pressure and pressure gradient in abutment zone of coalseam neighboring workings. Klinkburg effects and stress liberation by coalseam discharging gas make gas flow increase obviously in hole....

Transitive dynamic caustic model experiments were carried out with a transparent birefringence material on a dynamic caustic measuring system. The propagation of cracks in man made jointed materials and the effects of a joint to stress waves were investigated, and the general regularity of crack propagation across a joint was gained. The research results show that the direction of its propagation is different from the original one after a crack has crossed a joint and the propagation of a crack is relative...

Transitive dynamic caustic model experiments were carried out with a transparent birefringence material on a dynamic caustic measuring system. The propagation of cracks in man made jointed materials and the effects of a joint to stress waves were investigated, and the general regularity of crack propagation across a joint was gained. The research results show that the direction of its propagation is different from the original one after a crack has crossed a joint and the propagation of a crack is relative to the angle between the slotted cartridge and the joint and the distance between the bore hole and the joint. The analysis of the dynamic stress intensity factor for the tip of cracks induced by blasting shows that there are its two peak values when a crack crosses a joint because of the effect of the joint.
