运用成因地层分析方法,从剖面分析入手,划分、对比各级成因地层单位,研究其空间上的沉积构成,确立了涟邵煤田金竹山矿区测水组合煤岩系相当一个完整一级成因地层单位(沉积幕)。主要含煤期第一沉积亚幕又可进一步划分三个生长层序,代表了障壁-泻湖-潮坪体系的填积-侧积-填积-进积的充填过程。并以此为重点,选择生长层序作为编图单位,系统地分析、研究了本区聚煤特征和沉积模式,为探讨矿区内煤层的聚集分布规律,提供了可靠的依据。图8,参2。
By using genetic stratigraphy analysis method, starting from the profile analysis, dividing and comparing the stratigraphic units at various levels and studying their spatial depositional composition, the water logging combination coal-rock series of the Jinzhushan mining area in Lianshao coalfield is established as a unit of complete primary genesis (Deposition curtain). The main sedimentary sub-curtain of the first coal-bearing phase can be further divided into three growth sequences, which represent the filling-lateral-sediment-filling process of barrier-lagoon-tidal flat system. Based on this, we selected the sequence of growth as the unit of coding and systematically analyzed and studied the characteristics of coal accumulation and sedimentary model in this area, which provided a reliable basis for discussing the rules of coal seam accumulation and distribution in the mining area.
