摘　　要：针对东林煤矿煤与瓦斯突出灾害预测指标研究不足的问题,采用资料收集及分析、实验室研究、现场考察等手段,收集分析了东林煤矿扭褶构造特征及历年煤与瓦斯突出情况,采用声发射技术及钻屑指标法对东林煤矿煤与瓦斯突出灾害预测技术进行了研究,确定了东林煤矿煤与瓦斯突出灾害预测敏感指标及其临界值,即钻屑解吸指标K1临界值为0.2 mL/(g.min1/2),钻屑量S临界值为15 kg/m,辅助声发射能量指标临界值为20。According to the insufficient study on the predicted indexes of coal and gas outburst disaster in Donglin Mine, the information collection and analysis, the indoor study, the site investigation and other means were applied to collect and analyze the torsion fold struc- ture features and the coal and gas outburst conditions over the years in Donglin Mine. The acoustic emission technology and drilling cutting index method were applied to study the prediction technology of the coal and gas outburst disaster in Donglin Mine. The sensitive index and the critical value of the coal and,gas were set up. The critical value of the drilling cuttings desorption index K1 was 0. 2 mL/（ g . min^1/2）, the critical value of the drilling cuttings quantity S was 15 kg/m and the critical value of the auxiliary acoustic emission energy was 20.
