【摘要】:基于煤體自燃的一般理論,結(jié)合鑫安煤礦1307刀把工作面的特殊情況,設(shè)計了具體的"三帶"監(jiān)測方案,根據(jù)前期部分實測數(shù)據(jù)并結(jié)合數(shù)值擬合的方法預(yù)測了工作面采空區(qū)"三帶"的分布規(guī)律。后期回采過程中進(jìn)一步現(xiàn)場實測了"三帶"的分布范圍,選取D1測點對數(shù)據(jù)進(jìn)行Spss分析,分析結(jié)果與預(yù)測范圍相似度極高,最終確定"三帶"的分布范圍:散熱帶0~12m,自燃帶12~27m,窒息帶大于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.
