Study on Rockburst by Equivalent Material Simulation Tests

  • This paper puts forward a new equivalent coefficient E/λ in equivalent material simulation test on rockburst, where E is elastic modulus and λ is descending modulus. The paper concludes that different rockbursts can be simulated by the equivalent materials with different values of E/λ. A series of brittle failure equivalent materials are developed and can be used in different types of rockbursts tests. For the circular chamber rockburst, the simulation tests are made and prove that the developed equivalent materials are suitable for the simulation tests of rockbursts. The tests also demonstrate that there is a critical load for rockburst in circular chamber and the theoretical analysis result is verified.
