【摘要】:基于煤体自燃的一般理论,结合鑫安煤矿1307刀把工作面的特殊情况,设计了具体的"三带"监测方案,根据前期部分实测数据并结合数值拟合的方法预测了工作面采空区"三带"的分布规律。后期回采过程中进一步现场实测了"三带"的分布范围,选取D1测点对数据进行Spss分析,分析结果与预测范围相似度极高,最终确定"三带"的分布范围:散热带0~12m,自燃带12~27m,窒息带大于27m。
[Abstract]:Based on the general theory of coal spontaneous combustion and combined with the special situation of Xinan Coal Mine's 1307 knife-handle face, a concrete "three-belt" monitoring scheme is designed. Based on the measured data and numerical fitting method, the distribution law of "three zones" in goaf of working face is predicted. In the later mining process, the distribution range of the "three zones" was further measured on the spot, and the data were analyzed by Spss at D1 measurement point. The analysis results were highly similar to the predicted range. Finally, the distribution range of "three belts" was determined as follows: scattered tropical zone 0 ~ 12 m, The spontaneous combustion zone is 12m ~ 27m, and the asphyxiated zone is more than 27m.
