| 摘 要： | 通过对采空区煤炭自燃"三带"的理论和标准进行分析,结合梁宝寺煤矿3107综放工作面现场"三带"的观测数据,分析了后部采空区温度、CO和O2浓度的变化规律,并依据采空区氧化升温带长度,确定出自燃"三带"的范围。这种现场观测方法简单、比较容易实现,可以准确划分开采过程中采空区的自燃"三带",为后续工作面开采的防灭火工作提供科学依据。

| Abstract: | Through the analysis on the theory and standard of "three zones" of gob spontaneous combustion and in combination with the observation to the "three zones" in 3107 fully mechanized caving face,this paper analyzed the change regularity of temperature and CO and O2 concentrations in the rear gob and determined the range of the "three zones" of spontaneous combustion according to the length of oxidization temperature-rise zone in the gob and the shortest ignition period of the coal seam.This site observation m... |
