摘要
为了掌握义安矿煤与瓦斯突出区域预测指标及临界值,对义安矿瓦斯地质参数和区域预测参数进行分析,并对其区域预测的参数进行了简化,提出了采用钻屑解吸指标作为区域预测的指标,并结合生产验证了其临界值Δh2=293 Pa,Δh2大于293 Pa区域为突出危险区,Δh2小于293 Pa区域为突出威胁区。
In order to have the predicted index and critical value of the coal and gas outburst area in Yi an Mine,the gas geological parameters and the area predicted parameters of Yi an Mine were analyzed.The area predicted parameters were simplified.The paper proposed the desorption index of the drilling cutting as the predicted index of the area.In combined with the mine production,the critical value was confirmed as Δh2=293 Pa.When Δh2 is higher than 293 Pa,the area would be the gas outburst danger area and when ...
