关于煤系沉积相模式的研究,可以重建成煤环境,对煤层预测,寻找煤气田,煤田,煤田地质勘探方案的部署,地上资源的开发及矿产的综合评价都具有重要的指导意义.作者应用Г·А·伊万诺夫教授的相一大地构造的方法,联系我国煤田中的一些典型事例,对不同沉积环境的煤系形成过程及其地壳运动作用的变化关系作了较系统的分析.例如对滨海煤层沉积环境及沉积相序的形成和特征;滨海煤层石灰岩顶板形成模式及地质作用控制下的动态分析;滨海煤层的分叉特点及其形成过程的综合动态分析;大陆及滨海大陆相的成煤地质作用及其对煤层原生构造变化的影响等的综合分析.从而找出煤层变化的一定规律,并进行煤层分叉的生因分类,为煤田预测,地质勘探部署以及对煤炭资源的最终评价等提供理论依据.
The researches on coal facies sedimentary facies model can reconstruct into coal environment, which has important guiding significance for coal seam prediction, gas field seeking, coalfield and coalfield geological prospecting plan deployment, ground resource development and comprehensive evaluation of mineral resources. Prof. Ivanov’s method of tectonism and tectonics, and in connection with some typical examples in China’s coalfield, systematically analyzed the relationship between the coal formation process and the crustal movement in different depositional environments. Such as the formation and characteristics of sedimentary environment and sedimentary facies of the seashore coal seam; the dynamic analysis of formation pattern and geological control of limestone roof in the seabed seam; the bifurcation characteristics of the seashore coal seam and the comprehensive dynamic analysis of the formation process; Coal geological formation and its impact on the changes of the primary structure of the coal seam and so on to find out the law of the coal seam variation and to classify the cause of the coal seam bifurcation for the coalfield prediction, The final evaluation to provide a theoretical basis.
