位于祁连山中段的肃南县法拉沟井田,含煤岩系为晚石炭世浅海型海陆交互相含煤建造。通过对法拉沟井田煤炭勘探地质资料的综合分析研究后,论述了法拉沟井田含煤岩系的岩性、厚度、物性、含煤性及可采煤层的结构、厚度及变化规律、物性等特征,结合区域沉积特征,提出了对该区域含煤建造的几点认识,为今后找煤提供参考。 Located in the mid-Qilian Mountains Sunan Farah trench field, coal-bearing rock series for the late Carboniferous shallow sea-land inter-phase coal-bearing construction. Through the comprehensive analysis and study of the geological data of coal exploration in the Farah minefield, the lithology, thickness, physical properties, coal-bearing property and the structure, thickness, variation and physical properties of coal-bearing rocks in the Farah minefield are discussed. Characteristics, combined with regional sedimentary characteristics, put forward some understanding of coal-bearing construction in the region, to provide reference for coal in the future.
