【摘要】 矿山火灾中由于煤的自燃引起的火灾占有很大比例,因此自然发火是矿井防灭火工作中的治理重点。为了减少和消除煤炭自燃所带来的危害,科学地鉴定出煤的自然发火倾向性和准确地确定自然发火期对煤炭自然发火防治具有极其重要的意义。 本论文首先介绍了一下目前国内外在煤的自燃倾向性及自然发火期的研究现状。在煤的白燃及热分析动力学等方面的基础知识上,结合对神东矿区3种煤样进行热重实验的基础上,得出了煤韵活化能、指前因子等动力学参数。对基于活化能指标的煤的自燃倾向性及自然发火期进行了初研究。 经过初步研究发现,该方法是科学的、客观的,对煤矿安全状况管理、评价有重大意义。更多还原

【Abstract】 The fire caused by spontaneous combustion of the coal occupies very large proportion in the mine fire of the summary, so it is administration focal point in the mine defending and putting out the fire. In order to reduce and dispel the danger brought from spontaneous combustion of coal, scientific qualify the spontaneous combustion tendency of coal and accurately fix the spontaneous combustion period of coal that it have important meaning extremely to prevent and cure spontaneous combustion of the coal.This thesis introduce current situation of domestic and international in spontaneous combustion tendency and spontaneous combustion period of coal at present at first. On the rudimentary knowledge of spontaneous combustion of coal and thermal kinetic, combining the thermogravimetry experiment on 3 coal samples of Shendong mine area, this can draw such kinetic parameters as activation energy of 3 kinds of coal and pre exponent factor, etc. The preliminary study on the spontaneous combustion tendency and ...spontaneous combustion period of coal based on activation energy index is done..Discovered tentatively, this method is scientific, objective. It has great significance to the management of safety state, assessment of coal mine.更多还原
