我国煤田地质特点是煤盆地类型多样、煤系后期改造明显,为正确指导我国煤田的找煤方向和煤炭资源开发利用,在新一轮全国煤炭资源潜力评价的基础工作上,笔者提出了煤炭资源潜力评价工作中开展煤田构造研究的思路,研究内容为区域地质背景研究、构造形态和展布规律、构造成因和演化、构造控煤作用研究。依照我国煤田构造地质特点,提出赋煤构造单元的概念,将其定义为对煤系赋存的构造区划,具有构造单元和赋煤单元的双重涵义,总结归纳了5大赋煤构造区的煤田构造特征,为煤炭资源勘查和开发提供了可靠的地质保障。

The diversity of coal basins and the late intensive reformation of coal series were the remarkable characteristics of Chinese coalfield geology.To guide th e orientation of searching coal resources and value of coal exploitation and utilization, the coalfield structure research was finished works in the coal resources potentia I evaluation of China.In this paper, new thought of coalfield structures research in coal resources potential evaluation was introduced.The main research contents could be summarized in several aspects, including regional geological setting, structural framework and distribution law, tectonic origin and evaluation, tectonic control of coa I.In accordance with the complex conditions of coal field geological structure and the significant deformation of coal-measures, the paper suggested the concepts of coa I occurrence tectonic units defined as the tectonic division of coal-measures occurrence with double meaning of tectonic units and coal occurrence units.The coalfield st ructure characteristics of five coal occurrence districts were summarized, which supplied the dependable geological basement for coal resources exploration and develo pment layout planning in China.
