摘要
聚煤规律研究对煤田地质勘探和煤矿安全生产布局都具有重要的现实意义。为了更深入研究湖南龙潭煤系的聚煤规律,层码值被提出来并参与分析。层码值的提出不仅补充了聚煤规律研究的技术参数,更重要的是使聚煤作用在层序上的变化规律实现了量化研究。结果显示,湖南龙潭煤系的经典参数都具有较强的区域分布特征;主采煤层层码值、相对层码值、可采煤层平均层码值、平均相对层码值都比较一致地表明,湖南龙潭煤系最佳聚煤环境是由盆地中央向边缘逐渐迁移。研究表明经典技术参数分析有助于查明煤系聚煤规律;层码值的应用更有利于分析煤层在层序上的分布和变化规律。
The coal accumulation pattern study has momentous realistic significance in coal geological exploration and coalmine safety in production overall arrangement.In order to further study Longtan coal measures coal accumulation pattern,layer code values to quantify stratigraphic successions have been extracted and participated in analysis.The extraction of layer code value is not only replenished technical parameters to study coal accumulation pattern and what’s more,realized quantification study on sequential variation pattern of coal accumulation.The result has shown that the classical parameters of Longtan coal measures in Hunan have greater regional distribution characteristics.While main mineable coal seam layer code value,relative layer code value,supplemented by mineable coal seam average layer code value,average relative layer code value are in agreement and shown that the coal measures best coal accumulation environment is migrated from basin center toward marginal part.The study has shown that the classical technical parameters analysis can contribute to identify coal measures coal accumulation pattern,the application of layer code value is better for analysis of coal seams distribution on the sequence and their variation pattern.
