摘要
笔者近三年在该区进行地质勘查工作,通过二维地震和施工大量钻孔发现盆地内煤层变化较大,富煤带仅分布在盆地南部30平方千米范围内,对巴里坤矿区黑眼泉-段家地井田聚煤坳陷内富煤带与聚煤古地理和古构造的关系进行了分析研究,阐述了井田内煤系主要成煤地带分布于山麓相带和主河流河床之间的河湾处,未被冲刷,为河漫滩成煤带,为今后的地质勘探和煤矿开采提供可以借鉴的经验。
nearly three years work in the area with geological exploration.Through the 2D seismic and a large of borehole surverying has found in a larger change of the coal basin, which with only coal dressing in the south of 30 square kilometres.Within the research of the relations of coal-mining paleogeographic and paleostructure,which in the heiyanquan-duanjiadi field coal dressing depression of the Ba Li Kun town mining area. That described the main coal zones in the field which located in the bay of the piedmont facies zone and the main riverbed .Which is the coal zones of the flood plain that have not been washed, we can draw on the experience for future geological exploration and coal mining.
