摘要
煤炭在不同氧化阶段会释放出不同的指标气体,与煤体温度有着良好的对应关系。由于良好的指标气体本身具备的单一性、规律性和灵敏性的特点,利用指标气体预报预测矿井自燃火灾近年来得到了较好的应用,大大提高了矿井防灭火工作的准确性。通过研究开滦矿区自然发火指标气体的产生规律,在实验的基础上提出了4项自燃火灾燃烧状态判定准则,同时可作为预报预测自然发火的辅助指标气体,与其它指标气体结合可提高自然发火预报的准确性,对矿井防灭火有重要的指导意义。
Different gases will be generated at different oxidation stage of coal sample which have a good correspondence with the temperature.It has been widely used to predict the spontaneous combustion in coalmines and it helps to improve the accuracy of prediction greatly because of their special characters such as unicity,regularity and sensibility.The indicator gases predicting coal spontaneous combustion are determined basing on the laws of gas released from oxidizing coal with temperature,and four judgment criteria are put forward for the combustion regime analysis,by them they can be used as auxiliary index for the spontaneous combustion prediction too.Combined with other indicator gases,it can help to improve the accuracy of prediction greatly and is helpful to the mine fire combat and protection.
