A multi-dimensional coupling method for calculating mine whole-wind-network outburst shock wave propagation characteristics

The invention discloses a multi-dimensional coupling method for calculating mine whole wind network outburst shock wave propagation characteristics. The multi-dimensional coupling method comprises outburst source near source roadway FLUENT multi-dimensional calculation, far source roadway Flowmaster one-dimensional calculation and an MPCCI multi-dimensional coupling calculation method. Aiming at the characteristics of impinging airflow around the prominent source roadway, a two-phase flow model of pulverized coal gas and solid gas is established. By utilizing FLUENT calculation simulation, attenuation characteristics and attenuation factors of outburst shock waves under different roadway types are obtained. On the basis of the conclusion, one-dimensional simplification is performed on a far-source tunnel branch, an equivalent pressure loss and an outburst pressure source equivalent attenuation curve of a tunnel structure are determined, and propagation characteristics of outburst shockwaves of the far-source
