摘　　要：煤与瓦斯突出预测预报是防突的一个重要方面,介绍了理论分析和实验室条件下,工作面煤与瓦斯突出预测指标△h2临界值的确定方法和结果。通过在现场的实际应用,显示了该方法在提高掘进速度、减少不必要的防突措施上的优越性。The forecast of coal and gas outburst is an important aspect of outburst prevention. The paper introduces the determination method and the result of coal and gas outburst risk prediction index △h2 in working face with theoretical analysis and laboratory condi- tions. The practical application in the field shows the superiority of this method in improving the driving speed and reducing unnecessa- ry outburst prevention measures.
