    Abstract
  • A special test apparatus has been designed and used to study the effect of high-pressure gas on the deformation and failure of coal and rock. Dynamic ruptures of coal and rock are carried out by gas decompression. The results show that low gas decompression rate only causes deformation of coal specimens slightly while high gas decompression rate leads to fracture and outburst phenomenon. The degree of damage of rocks depends on not only the gas decompression rate but also the gas pressure. Violent fragmentation occurs when gas decompression rate and high saturation pressure reach critical values. According to the relationship between the decompressed gas pressure and strain, the critical gas pressures are determined for the fracture and fragmentation of specimens.
