煤与瓦斯突出局部预测对矿井的防突工作十分重要，本文根据大宁煤矿3号煤层的实际情况，进行实验室和现场考察相结合的研究，分析认为：相同压力下构造煤的实测K1值与原生煤之间的差距更显著，而两者实测Δh2值的差距并不是很明显；钻屑解吸指标K1值在地质异常区波动浮动很大，并且随构造煤厚度的变化K1值也会相应波动，而钻屑量S值则变化均不明显；因此，最终认为大宁煤矿3号煤层的突出预测指标K1值更敏感，确定在进行矿井突出局部预测时应首选K1值。本文所提出的局部突出预测指标敏感性分析的方法，可为类似矿井瓦斯突出预测和防治工作提供一定借鉴。%It is very important of partial prediction of coal and gas outburst for outburst control in coal mine .Ba-ses on the actual situation of No.3 coal seam in Daning coal mine, conducts integrated research on laboratory experi-ments and field investigation.The analysis points out that the measured values of K1 between deformed coal and raw coal are more different under the same pressure, and the difference of the measured values ofΔh2 is not obvious.The values of K1 obviously changes in geologic anomaly zone, and also changing with the change of deformed coal thick-ness.However the change of drilling cuttings weight values S is not obviously.Therefore the index K1 is more sensitive for coal and gas outburst, and it is ensured to the first chioce on coal mine outburst partial risk prediction.The meth-od of partial outburst prediction index sensibility provides a reference for similar coal mine on gas outburst prediction and prevention andtreatment.
