description In order to research on gas exploration shock wave spread law via a one-way bifurcation pipeline, the gas exploration pipeline experimental system and numerical calculation model were established. By adopting the comparative analysis of experiments and numerical modeling, it conducted researches on the attenuation and shunt characteristics of the gas exploration shock wave via the one-way bifurcation pipeline and obtained the computational formulas for shock wave attenuation coefficients of branch pipelines and straight pipelines and shock wave shunt coefficients of branch pipelines. As the research result showed that when the pipeline bifurcation angle was fixed, the larger the shock wave overpressure was, the larger the overpressure attenuation coefficients of straight pipelines and branch pipelines were. When the shockwave overpressure was fixed and the one-way bifurcation pipeline angle increased, the shock wave overpressure attenuation coefficients of branch pipelines would be aggregated and the shock wave overpressure attenuation coefficients of straight pipelines would be decreased, which reflected the shunting action of the shock wave in branch pipelines and straight pipelines; the larger the branch pipeline bifurcation angle, the smaller the shunting action for straight pipelines. The research achievements in the paper had important significance for the assessment of structures damage in mine laneways gas exploration accidents and installation of the antiexploration manhole cover, which further enriched gas exploration spread theory.
