摘要
采空区自燃"三带"的确定是做好矿井采煤工作面防灭火的基础工作之一,正确地划分采空区"三带"范围,是制定相应防火措施的重要依据。利用大同煤矿集团同家梁矿现有束管系统以及光纤温度测试系统,通过在8832综放工作面采空区两巷布置气体浓度和温度测点,准确地测得了该工作面采空区自燃"三带"范围及分布特征,为同家梁矿及大同矿区的采空区防灭火工作提供了技术支撑。
The determination gob spontaneous combustion “three zones” is one of the fundamental work for fire prevention and control of mine working face. The correct division of gob “three zones” can provide reference for formulating corresponding fire prevention measures. Using Tongjialiang Mine existing beam tube system and optical fiber temperature test system, through layout of gas concentration and temperature measuring points in the two roadways of 8832 mechanized caving face, determination and distribution of gob spontaneous combustion “three zones” of the working face is measured accurately, and it also provides technical support for the gob fire prevention work in Tongjialiang Mine and Datong Mining area.
