摘　　要：针对叙永一矿实际瓦斯地质条件,将钻屑量指标S和钻孔瓦斯解吸指标K1作为其煤层突出危险性预测的敏感指标,并以历史数据和现场测得的数据为基础,确定了煤层的钻屑量S和钻屑瓦斯解吸指标K1的临界值分别为5.20 kg/m和0.41 mL/(g·min1/2)。通过最小均方差法对煤层突出预测指标进行敏感性分析发现,钻屑量指标S的敏感性相对于钻屑瓦斯解吸指标K1较好,其敏感指标及临界值对叙永一矿后续防突措施的制定和瓦斯治理方案设计具有现实指导意义。According to the actual geological conditions of Xuyong first coal mine,the drilling cuttings volume index S and the drilling cutting gas desorption index K1 were selected for the prediction of coal seam outburst.Based on historical data and field experiment data,concluded that the critical values of the drilling cuttings volume index S and the drilling cutting gas desorption index K1 of coal seam were5.20 kg/m and 0.41 mL/(g·min1/2)respectively.Through the analysis of sensitivity index by the minimum mean square deviation method,it is found that the sensitivity of the drilling cuttings volume index S is better than that of the drilling cutting gas desorption index K1.The sensitivity index and critical value are of practical significance on the follow-up gas control and outburst prevention measures for Xuyong first coal mine.
