晋北煤矿5号煤层风氧化分布规律研究

Study on No.5 Coal Seam Wind Oxidation Characteristics Distribution Law in Jinbei Mine

在对晋北煤矿5号煤层地质状况和煤层风氧化特征进行详细分析的基础上,从构造因素、上覆基岩厚度、煤层顶板性质及煤层结构等角度切入,对其风氧化分布规律进行了探索研究。结果表明,该矿5号煤层风氧化作用主要受地质构造控制,以垂向风氧化作用为主,其规律为风氧化带沿井田东部背斜轴部分布,受顶板岩性及其裂隙发育程度影响,不同地点煤层风氧化程度有所不同。该研究为矿井生产规划提供了地质依据。

Based on the specific analysis of No. 5 coal seam geological condition and coal seam wind oxidation characteristics of Jinbei Mine, wind oxidation characteristics distribution law was studied from structural factor, thickness of overlying rock, coal seam roof feature and coal seam structure. The result showed that the No. 5 coal seam Wind Oxidation was mainly affected by geological structure, with mainly vertical wind oxidation, which distributed along the east mining field anticline axis, influenced by lithology of coal seam roof and crack growth degree, different sites of coal seam, wind oxidation degree is different, the study provides geological basis for mine production.
