摘要
根据二道岭矿区实际情况,通过大量数据测试,综合考虑煤体结构特征及瓦斯放散初速度、煤的坚固性系数、煤层瓦斯含量、瓦斯吸附常数及瓦斯压力等瓦斯参数,采用单项指标法、煤层瓦斯含量法及综合指标等方法对各矿井主采煤层进行了煤与瓦斯突出区域预测。预测结果表明:陡崖沟井二1上煤层,哈沙图井二1上、二1煤层,别立沟井二3煤层和八仙井二3煤层的预测工作面为突出危险区。预测结果对于提高各矿井防突措施的有效性和针对性具有一定的参考价值。

Abstract
According to actual conditions of Erdaoling Mining Area, with great data test and measured, the seam structure features as well as the initial speed of th
e gas emission, the hardness coefficient of seam, the seam gas content, the gas adsorption constant, gas pressure and other gas parameters should be comprehensive
ly considered.The single index method, the seam gas content method and the comprehensive index method were applied to the regional prediction of the coal and gas
outburst for the main mining seam in each mine. The prediction results showed that the No.21 Top Seam in Douyagou Mine Shaft, the No.21 Top Seam and No.21 Seam
in Hashatu Mine Shaft, the No.23 Seam in Beligou Mine Shaft and the No.23 Seam in Baxian Mine Shaft were predicted and the coal mining faces in those seams woul
d be dangerous.The predicted results would provide certain reference values to increase the efficiency and aiming of the outburst prevention measures of each mine.
