辽源西安煤矿含煤盆地演化及找煤方向

本文依据区域地质、普查勘探和开采资料的综合研究,对辽源西安矿及外围区域成煤构造环境、含煤岩系与火山岩的关系的分析。确立了两期火山喷发和两期含煤沉积相。提出了辽源地区煤炭资源仍有宏观远景。创新性提出含煤岩系的二元结构观点,指出今后辽源地区继续找煤的前景和方向为盆地内久大组。

Coal-bearing basin evolution and coal-looking direction of Liaoyuan Xi'an coal mine

Based on comprehensive study of regional geology, general survey exploration and mining data, the authors analyze the relationship coal-forming tectonic environment, coal-bearing strata and volcanic of Liaoyuan Xi＇an coal mine and peripheral regions. We establish two-stage volcano eruption and two-stage coal-bearing sedimentary facies, innovatively put forward binary structure of coal-bearing series. It pointed out that finding prospect and direction of Liaoyuan area, Jiuda Group.
