Numerical simulation determination method of deep high-stress roadway drilling pressure relief parameter

The invention discloses a numerical simulation determination method of a deep high-stress roadway drilling pressure relief parameter. Before simulation is carried out, a test roadway surrounding rock sample is firstly subjected to a loading and unloading test in a laboratory, an attenuation relationship between a rock sample strength parameter and a damage variable is obtained by fitting and is embedded into a FLAC<3D> (Fast Lagrangian Analysis of Continua) built-in strain softening constitutive model, and an actual measurement mine pressure expression law of a test roadway is taken as a known characteristic value to carry out inversion on the numerical calculation model parameter of a rock mass. A deep roadway drilling pressure relief numerical calculation model is established to simulate and analyze the influence law of a pressure relief drilling orientation, pressure relief opportunity and drilling parameters (diameter, length and inter-row spacing) on the stability of roadway surrounding rock, and a determination method of each factor which affects a pressure relief effect is put forward, and a drilling pressure relief technology system is perfected. The numerical simulation determination method considers the mutual action relationship of a pressure relief degree and the stability of the surrounding rock while pressure relief drilling parameters are determined, and the designed pressure relief drilling can perform a maximum pressure relief effect on a premise that the stability of the surrounding rock is guaranteed. The method is simple and exhibits high application value.
