【摘要】 煤层自燃的研究分三个层面 :运用遥感技术调查区域性煤层自燃的分布和危害 ;运用煤岩学和地球化学等方法研究煤层自燃的临界值和气体释放规律 ;研制火灾样检测传感元件进行火灾的预测预报、抑制起火的最佳通风和建立控风、防灭火专家系统 ,进行煤矿火灾的综合防治。本文在阐述煤层自燃三个方面研究现状和进展的同时 ,着重回顾和论述了煤岩学和地球化学研究对煤层自燃灾害研究的若干问题 ,提出了煤层火灾综合防治的对策。更多还原

【Abstract】 There are three methods in researching the disaster of spontaneous combustion in the coalbeds:remote sensing technology which is used to investigate distribution and disaster extent of spontaneous combustion of coalbeds;the methods of coal petrology and geochemistry which are used to determine the critical temperature and the law of releasing gas in spontaneous combustion of coalbeds;prevention and cure of the fire disaster through developing sensing element measuring the fire and improving condition of ventilation and so on.The paper expounds the history,present situation and progress of the fire disaster in the coalbeds,and lays its stress on discussing some problems of the fire disaster in the coalbeds using the methods of coal petrology and geochemistry.On the basis of the above dicussion,the countermeasure of prevention is suggested.更多还原
