湖南白兔潭矿区荷田区段构造特征与找煤前景

煤炭是湖南省的主要能源,经过多年的勘探开发,暴露区和浅部的煤炭资源已基本采完,因此,在隐伏区寻找新的煤炭资源已成为当务之急。隐伏区找煤主要指“三下”(老地层下、构造下和红层下)找煤,而“老地层下和构造下”找煤主要是指利用推覆构造理论寻找新的煤炭资源。为了深化对区域构造和煤田构造发育规律的认识,为本区煤炭资源勘探和矿井生产地质保障提供新思路、开拓新领域,以当代构造地质理论为指导,结合已有资料,对白兔潭矿区荷田区段的煤田构造进行了研究,揭示了煤田的构造格局,提出了该区可能存在的两种构造模式,对该区找煤前景做出了科学评价,指出了可供进一步勘探的有利区段。

Structural characteristics and coal searching prospect in Hetian district Of Baitutan mining area in Hunan

Coal is the main energy resource in Hunan province, through the exploitation for many years, shallow coal resources in exposed area have been mostly exhausted, therefore looking for new coal resources from hidden areas has become very urgent. Seeking coal in hidden areas is mainly to seek coal under old formation, structure and red beds, and seeking coal under old formation and structures mainly means using nappe structure theory to look for new coal resources. This article evolved a systematic and deep research on structural features of coal field in Hetian district of Baitutan mining area with the guide of the current tectonic geology theory and data that we already have for the purpose to deepen the knowledge of area structural and developing rules of coal field structues, toafford new thinking and extend new areas for the coal resources exploration and mine production by geology safeguard in this area. This research exposed tectonic structures in coal fields, proposed two possible structural modes, evaluated scientifically coal searching prospect and pointed out favorite districts for further exploration.
