西川煤矿煤系地层原生CO赋存及涌出规律研究

Study on the Native CO Occurrence and Emission Law in Coal Series in Xichuan Coal Mine

介绍了西川煤矿各个采掘地点原生CO含量的测定技术及其赋存规律的研究方法,得出了CO涌出量与煤层自然发火之间的关系、西川煤矿回采和掘进工作面原生CO含量的临界值,为通过CO气体预测自然发火指标提供了更科学的依据,从而确保及时、准确地预测矿井火灾。

This paper introduced research methods of native CO content determination techniques and its occurrence regularity in every mining site in Xichuan Coal Mine, and obtained the relationship between CO emission volume and seam spontaneous combustion, the critical value of native CO content in Xichuan coal mining and driving working face, which provided a more scientific basis for predicting spontaneous combustion by CO gas, so as to ensure timely and accurately predict mine fires.
