Investigation of Formation Process and Intensity of Coal and Gas Outburst Shockwave

The shock wave of a coal and gas outburst is high-pressure high-speed impact airflow formed rapidly after the outburst. propagation destroys ventilation facilities causes destruction system. theoretical research on great significance. In order to deeply understand formation mechanism wave, this paper draws theory theoretically analyze microscopic process wave. main difference between general that has solid–gas flow zone in zone. calculation formulas pressure, density, temperature other parameters before are derived. After passes through, density roadway air will change suddenly. relationship expression pressure intensity derived, which can reflect role pulverized facilitate understanding calculation, concept equivalent sound velocity coal-gas proposed, direct strength attempted. This helpful improve essence It also significance disaster relief.
