| Abstract: | To effectively carry out gas workface governance,according to the protective layer mining theory,set a new protective layer under the Mine 131303 face mining technology on-site visits,study results show that under the protective layer 11-2 on coal mining were protective layer 13-1 to eliminate the effect of coal outburst obvious.The results of similar mining conditions of the mine coal and gas outburst prevention and comprehensive management of gas has a certain significance. |

| Keywords: | under protective layer coal and gas outburst gas extraction protective effect |
