摘　　要：将功效系数法应用于煤与瓦斯突出区域预测中,选取综合指标D值和K值、煤层瓦斯压力p、瓦斯放散初速度Δp、煤的坚固性系数f、地质构造T作为突出预测的评价指标,运用层次分析法和平均值法求得各评价指标的综合权重,以总功效系数值作为评价标准,确定煤层突出危险等级。选用贵州盘县矿区12组实测样本进行功效系数法预测效果检验,预测结果与实际情况一致,验证了功效系数法用于突出预测的合理性和准确性,为煤与瓦斯突出区域预测提供了一种新思路。Based on the principle of efficacy coefficient method,six factors including comprehensive index of D and K,gas pressure of coal seam,the initial speed of methane diffusion,the firmness coefficient,types of the coal damage,geological structure were selected as evaluation indices,used AHP and average method to obtain comprehensive weight,the total efficacy coefficient as evaluation criteria,determined coal seam hazard category.Use 12 samples of Pan County mines,Guizhou as tested examples,measurement results consistent with the actual situation,verify the rationality and effectiveness of the method,provides a new idea for coal and gas outburst regional prediction.
