中文摘要:
      综合分析湘东浏阳澄潭江矿区数十家开发安源煤系的小煤矿矿井地质资料,认为澄潭江矿区安源煤系是三角洲沉积体系所形成的.该三角洲是安源运动之后,江南古陆往东南注入湘赣海湾的一条古河流所形成的浅水高建设性三角洲,并经过三湾、三都2次区域性造陆运动的改造而最终演变成为一个千平方公里级的大型三角洲.研究表明,矿井地质资料非常精细地揭露了煤(矿)层及其附近围岩的沉积特征,可以用于更为精准的沉积环境分析;而综合多个煤层、多个矿井的矿井地质资料的整体分析,并辅以适当的浅表地质调查,是完全可以揭示三角洲这种复杂沉积体系的形成及其发展演变历史的.
英文摘要:
      Based on the coal mine geological data of dozens of small coal mines development of Anyuan coal measures from the Chengtanjiang mining area of Liuyang in eastern Hunan, comprehensive analysis show that the Anyuan coal measures from Chengtanjiang mining area is formed by delta depositional system.The delta is a shallow water and high construction delta that formed by a river into the southeast of the Hunan-Jiangxi galf from the Jiangnan palaeocontinental after Anyuan movement, and eventually evolved into a large delta of thousand square kilometers after the transformation of two regional Sanwan and Sandu epeirogenetic. The research shows that the mine geological data actually revealed characteristics of coal (rock) layer and the surrounding rock, which is used for more accurate analysis of the sedimentary environment. Through integral analysis of the comprehensive mine geological data from multiple coal seams, multiple mine, especially supplemented with appropriate investigation of superficial geological survey, we can perfectly reveal the history of the formation and development of this complex sedimentary system such as delta, was perfectly revealed.
