摘　　要：针对中国工作面突出预测敏感指标及其临界值的研究现状,通过理论分析、实验室实验和现场测试等方法,提出采用煤钻屑瓦斯解吸指标Δh2值作为工作面突出的判定理论和敏感指标的判定方法,以潘一矿13-1煤层采掘工作面为研究对象,选用"三率"法和"灰色关联"分析方法对提出的理论进行了验证。采用钻屑瓦斯解吸指标Δh2作为采掘工作面突出的判定方法,解决了敏感指标间相互交叉的问题和临界值模糊性难题,提高了敏感指标的适应性。Based on current study on sensitivity index and its critical value of outburst prediction at coal face in China,this paper proposes an assessment method that uses coal drilling cutting gas desorption index △h2 as a critical index for assessing outburst in coal face based on theoretical analysis,laboratory experiments and site test.A case study at 13-1 coal mining face in Panyi coal mine demonstrates the method proposed using three rates method and grey correlation theory.The problems that crossing of sensitivity indexes and fuzziness of critical values are overcome using coal drilling cutting gas desportion index △h2 as a critical index for outburst in coal face.In addition,the adaptability of sensitivity index is improved.
