| 摘 要： | 根据传热学和化学动力学理论,推导出采空区下限氧浓度和氧化带宽度的计算方法,并分析了煤自燃与氧浓度、氧化带宽度与漏风强度的关系.在此基础上,对采空区注氮后相关参数的变化规律进行了定量研究.根据理论推导,确定出防治采空区浮煤自燃的最佳注氮参数,为采空区注氮后自燃火灾的预测及防治提供了理论依据.参4.

| Abstract: | Calculating method is deduced to gain lower limit of oxygen concentration and range of oxidation zone from heat-transfer and chemical kinetics theory.Both connections coal self-ignite with oxygen concentration and range of oxidation zone with air-leak intensity are analyzed.Change rule of correlative parameter is quantitatively researched after nitrogen injection in gob.According to theoretical calculation,the best parameter of nitrogen injection is conformed to control float coal self-ignite in gob.It offers a theoretic criterion for forecasting and controlling float coal self-ignite.4refs. |
