In the increasingly complex mining environment with increasing depth,there are significant gas outburst hazards in coal mine tunnels,and due to the limitations of traditional extraction techniques,mining safety cannot be improved.Therefore,based on the risk of gas outburst in the 15#coal seam of the case coal mine,it was decided to apply directional long drilling gas extraction and outburst prevention technology.The results showed that after applying this technology,the overall gas extraction effect of the coal mine was good.The research can provide data support for the optimization of subsequent gas extraction plans.
