一、前言 在水分对煤炭自燃的影响的论题中包括有许多的报告,其结论有所谓水分会促进煤炭自燃的说法以及相反地所谓水分会抑制煤炭自燃的说法,另外也有因煤炭种类的不同而影响有所差异的一类报告。 这些报告都是以寻求煤炭的氧化性与水分的关系为目的的,并未涉及到井下煤炭自燃与水分的关系问题。其次,在对煤炭自燃进行室内试验时,也未搞清楚由于煤样水分的不同,试验结果究竟发生了什么样的变化。本文作者为了把上述各点搞明确,曾进行了一系列的实验,现发表其中的一部份。
I. INTRODUCTION There are many reports on the impact of moisture on the spontaneous combustion of coal. The conclusion is that there is a saying that the so-called moisture will promote spontaneous combustion of coal and conversely the so-called moisture will suppress the spontaneous combustion of coal. In addition, due to differences in the types of coal, A class of reports that have some impact. These reports are aimed at seeking the relationship between the oxidation of coal and water, and do not involve the issue of the spontaneous combustion of coal and water in underground coal mine. Secondly, when testing the spontaneous combustion of coal, we did not know exactly what happened to the test results due to the different moisture of coal samples. In order to clarify the above points, the author has conducted a series of experiments and now publishes some of them.
