Based on the basic characteristics of annular jet analyzed briefly, the velocity and the average methane concentration distribution formula of annular jet which draws flow contained in gas have been deduced in the fully developed field. When annular rotary jet injects across the main flow, its curved shape and the process of dispersing the upper corners gas accumulation of U shaped working face are analyzed. The influence of rotary frequency and the outlet area ratio of annular jet and circular jet on shooting range and curving degree is expounded. Through field experiment, it has been proved that the drawing airflow and the pulsing velocity characteristics of rotary jet can produce the gentle discharging effect which disperses the upper corners gas accumulation effectively and safely.
