摘要
地下采煤中“三带”高度的确定是进行邻近层或采空区瓦斯抽放钻孔布置的主要依据,而准确地预测“三带”高度,就必须弄清其影响因素。为此,不仅对覆岩破坏高度的影响因素进行了定性分析,同时运用灰色理论知识分析这些影响因素对覆岩破坏高度的影响程度,深化了对覆岩破坏影响因素的认识。
The confirmation of the height of ＂Three-zone＂ is the base of gas drifting core layout in nearby coal seam or gob. The influence factors of the height of ＂Three-zone＂ must be known to forecast it precisely. Therefore, not only the influence factors of the height of ＂Three-zone＂ is analyzed qualitatively, but also gray theory is used to analyze the influence of these factors on it in this paper and the acquaintanceship of the influence factors of overlying strata is deepened.
