郭二庄井田煤岩对比方法研究

Study on method of coal rock in contrast to Guo Erzhuang

郭二庄井田是优质无烟煤矿区,但受长期开采影响,资源渐趋枯竭,矿井开采水平逐渐向深部延伸,为指导巷道水平掘进层位的正确性,通过研究分析井田深部已施工的46个钻孔资料,总结出矿井深部可采煤层特征、标志层特征、层间距规律、岩性组合特点以及物性曲线的典型规律,经对比分析,得出适合郭二庄井田煤层进行煤岩对比方法和顺序。

Guo Erzhuang coalfield is a high-quality anthracite mining area, because of the long-term influence of mining,gradual depletion of resources, mining level gradually to the deep extension for the correctness of the guidance of roadway tunneling layer, so as to reduce the efficiency of enterprise management objectives, through the study of 46 borehole data of deep mine construction, summarize mine deep mining coal seam characteristics, mark feature layer, layer spacing rules,lithology combination characteristics and physical characteristic curves of typical law, by comparison analysis, obtained for guoerzhuang mine coal seam of coal and rock contrast method and the sequential.
