湖南省攸县黄兰矿区煤岩层综合对比研究

攸县是湖南最大产煤县,黄兰矿区为该县唯一产煤区。黄兰矿区由黄丰桥、兰村两个子矿区组成。该区煤系地层厚、岩性相变大、煤层多、煤层形态复杂,一直受到悬而未决的煤、岩层对比问题掣肘,区内找煤始终难见成效。本次研究采用多种方法进行综合对比,成功攻克了黄兰矿区多年来多家技术单位未解决的煤、岩层对比历史性难题,全区探获煤炭资源量3.43亿t,实现建国以来湖南乃至南方各缺煤地区最大的找煤历史性突破。

Integrated Correlation for Coal seams and rock strataon Huanglan mining area in Hunan province

Youxian is the largest coal producing county in Hunan province, and Huanglan mining area is the only coal producing area in the county.Huanglan mining area is composed of HuangfengqIao sub-mining area and Lancun sub-mining area,The formation of longtan formation in this area has a large sedimentary thickness and a large change of rocks and a number of coal seams,The coal prospecting in the area is restricted by the difficult problems of coal and rock formation.This study uses a variety of contrast methods to make a comprehensive comparison.A systematic and practical system of coal and rock correlation has been established for the first time,The comparison of coal and rock formations has been solved.The estimated coal resources is 343 million tons.It has realized the biggest coal finding achievements in Hunan and even in the South of China since the founding of the people"s Republic of China.
