崔家沟矿2207工作面煤自燃及防治措施

Discussion on the coal spontaneous combustion and prevention measures in 2207 mining face of Cuijiagou coal mine

根据铜川崔家沟矿2207工作面采空区温度传感器以及束管的氧气指标气体,通过收集的数据分析得到温度及氧气与采空区煤自燃"三带"的关系,确定煤自燃"三带"的分布范围,并提出了防止煤自燃的措施,对回采面的安全生产有重要的指导意义。

Based on the oxygen index measured by temperature sensor and beam tube monitoring system that installed in the gob of 2207 mining face,the paper analyzed the relationship of gob spontaneous combustion ＂three regions＂ with temperature and oxygen,determined the distribution of spontaneous combustion ＂three regions＂ and proposed the measures of preventing coal spontaneous combustion.
