摘要
谢一矿C15煤层为突出煤层,矿井为了在突出煤层瓦斯灾害综合防治中做到更有针对性,将C15煤层5121(5)工作面作为试验区进行区域突出危险性预测研究。试验表明:以单项指标法、瓦斯地质法、"综合指标D,K"法,并结合工作面掘进预测敏感指标分布特征的区域预测方法准确预测出5121(5)工作面的突出危险区域,预测结果极大地降低了矿井的防突投入。
C15 coal seam of Xieqiao coal mine is outburst coal seam.In order to provide more targeted methods to avoide coal and gas outburst,taking 5121（5） face of C15 as sample,do regional prediction of coal mining face with coal outburst in potential.Single index method,gas geological method,comprehensive index D and K method,regional prediction method are applied to predict area with outburst danger.The prediction can help to decrease outburst prevention cost.
