| 摘 要： | 为了查清丁集矿区B组煤层的沉积环境及其赋存规律,对井田内3个补勘钻孔中142件煤样进行了测试分析,特别对硼元素的分布特征及其沉积环境进行了详细的探讨与分析,结果表明:从4-1煤至8煤硼元素呈现总体下降的趋势;B组煤层沉积在以咸水为主导的多变环境下,且大部分煤层沉积在半咸水—咸水的环境中;多变的沉积环境致使B组煤中部分煤层出现分叉与合并现象、其厚度较薄且间距较小。

| Abstract: | For a thorough investigation of coal group B depositional environment and its hosting pattern in the Dingji mine area,have tested and analyzed 142 coal samples from 3 boreholes of the supplementary exploration in the minefield.Especially carried out detailed discussion and analysis on boron distribution pattern and depositional environment,and the results have demonstrated that: from coal seams No.4-1 to No.8,the boron content presents a falling tendency as a whole;coal seams in group B were deposited in a ... |
