摘　　要：在全面系统的收集了贵州金佳矿11223工作面开采前的瓦斯抽放资料基础上,通过实测煤层瓦斯基础参数,根据防治煤与瓦斯突出相关技术规范,采用残存瓦斯含量、残存瓦斯压力法和综合指标法对11223工作面进行了突出危险性评价。对11223工作面瓦斯抽放量及抽采率进行了计算,得出该工作面已经消除了突出危险性。Base on the systematic collections on the gas pre-drainage information of the NO.11223 coal mining face in Jinjia mine of Guizhou Province,according to the basic parameters of coal gas and the technical specifications of control of coal and gas outburst,evaluated the NO. 11223 coal mining face with the use of comprehensive indicator method, the residual gas content and the residual gas pressure. The calculation on the gas drainage quantity and the gas drainage rate from the coal mining face showed that the gas outburst danger was eliminated for the No.11223 coal mining face.
