摘要
通过在新柳煤矿231115综放工作面采空区预埋多组测温探头和束管系统,实测采空区余煤氧化产生的温度和气体成分,分析其变化规律,确定采空区的氧化"三带"的宽度及其随回采推进的动态变化规律,进而为新柳矿11煤的自然发火期预测提供基础数据。
By embedding groups of temperature probes and bundle tube system in the gob of 231115 fully mecha- nized mining face in XinLiu coal mine, the authors determine the width of oxidized ＂ three belts＂ and its dynamic change rule with stoping face propulsion by measuring the temperature and gas composition generated by the oxi- dization of residual coal in gob and analyzing the change rule, which provides basic data for forecasting the spon- taneous ignition period of 11 coal in Xinliu Colliery.
