摘　　要：为了确保新安矿井安全高效的生产,通过△h2的理论分析、实验室模拟和现场测试,分析了工作面钻屑瓦斯解吸指标△h2的突出敏感性,确定了△h2临界值为180Pa,并运用"三率法"对△h2及其临界值进行了分析。实践表明:该临界值适合新安矿,保证了煤矿安全生产。To ensure the safe and efficient production of Xin＇an mine, through Ah2 theoretical analysis, laboratory simulation and field testing, the outburst sensitivity of the coal-face cuttings gas desorption index △h2 is analyzed. It determines the critical value of △h2=180Pa, and uses＂ three rate method＂ analyzeds its critical value of △h2. Practice shows that the critical value is fit for Xin＇an mine, and ensures coal mines safety in production.
