摘　　要：煤与瓦斯突出危险性区域预测是煤与瓦斯突出煤层回采的先决条件。从杨河煤业22161工作面区域揭露煤层以及井下巷道钻孔定点取样,现场观察并测试了二1煤层煤的破坏类型、瓦斯压力、煤层瓦斯井下解吸量,实验测试了煤层瓦斯残存量、煤的瓦斯放散初速度和坚固性系数。结果表明:22161工作面区域二1煤层煤的破坏类型为Ⅳ~Ⅴ类;相对瓦斯压力(p)为0.02~0.06 MPa;瓦斯含量(W)为2.94~3.77 m^(3)/t;瓦斯放散初速度(Δp)为21~23 mmHg,坚固性系数(f)为0.13~0.16。综合单项指标法和地质分析法预测22161工作面区域二1煤层在预测范围内标高-91.9 m及以上范围内无突出危险。Prediction of coal and gas outburst risk in an area is a prerequisite for coal and gas outburst coal seam mining.In the 22161 working face area of Yanghe Coal Mine,coal samples were taken from the exposing coal seams and the underground roadway drilling holes.The failure type,gas pressure and gas desorption quantity of 2^(-1)coal seam were observed and tested.The residual gas content,the initial velocity of diffusion of coal gas and the coal hardiness coefficient of the coal seam were tested in experiment.The results show that the failure type of 2^(-1)coal seam in the 22161 working face area is classⅣ~Ⅴ.The relative gas pressure(p)was 0.02~0.06 MPa;the gas content(W)was 2.94~3.77 m^(3)/t;the initial velocity of diffusion of coal gas(Δp)is 21~23 mmHg;and the coal hardiness coefficient(f)is 0.13~0.16.Combined the single index method and the geological analysis method,it can be predicted that there is no risk of coal and gas outburst around the 22161 working face area within the predicted range above-91.9 m.
