综放面采空区氧气浓度场分布研究

Study on oxygen concentration field distribution in the gob of fully-mechanized caving face

采用现场观测和数值模拟的方法,对华亭矿区陈家沟煤矿3103工作面采空区氧气浓度场分布进行比较。现场观测数据真实,有利于分析问题,解决问题。而ANSYS FLUENT软件数值模拟方法更有利于排除一些复杂因素和现场检测的技术难题,实现采空区氧气浓度的较准确分布。结论表明:通过两者的结合能更好的实现对氧气浓度场分布的了解和预测,并对陈家沟3103工作面采空区煤自燃的预防措施进行指导。

By field observation and numerical simulation, the paper analyzed and Compared the gob oxygen concentration field distribu tion of Chenjiagou mine 3103 face. The conclusion shows that with the combination of field observation and numerical simulation, it is more favorable to predict the oxygen concentration distribution and provide a guideline to prevent gob coal spontaneous combustion.
