| Abstract: | According to the uneven gas emission from the mining period of 250205 coal mining face in Yanbei Mine and the actual conditions of the gas content over limits in the top corner of the coal mining face,with the analysis on the gas resources,the paper made the comprehensive gas prevention and control measures with the rational ventilation to the mining face,strata pressure releasing and water injection to pre-release the gas and local gas drainage.The gas control results showed that the application of the comprehensive prevention and control measures had highly reduced the gas contents in the air return gateway,top corner and goaf.The preset target was obtained and the safety production of the coal mining face was ensured. |

| Keywords: | goaf top corner strata pressure releasing in advance local gas drainage |
