华亭矿区聚煤规律及控煤因素分析

Coal Accumulating History and Coal Control ling Factor Analyses in the Huating Mining Area

以大量的钻孔资料为基础,研究了华亭矿区中侏罗世含煤地层的分布、含煤性和聚煤作用,通过编制华亭含煤盆地走向、倾向沉积剖面,分析了研究区含煤岩系的沉积旋回结构及煤层的分布情况,对华亭矿区控煤因素进行了总结评述,为今后煤矿生产及外围找煤提供参考。

The paper made a summary on struct ural characteristics of the Shangjing mine field by the use of geological data from exp loration in the minefield and mining produc tion.Figured out that the main structure fo rm in the minefield is fold, while the disti nguishing feature is convolute fold.The co mplicated structural framework was formed after multiple tectogenetic movements.Fou r stages of forming processes may be summed up:coal basin forming stage;first order fo lds and overthrusts forming stage;second a nd third order folds and a series of normal faults forming stage; tectonic system stac king,remolding and shaping stage.
