摘　　要：古构造控制的基底古地形隆坳并存,对彬长及麟北详查区煤层聚集影响较大,且规律性明显。众多河流向坳陷洼地浅湖淤填使巨厚煤层形成于坳陷洼地呈环带状展布。在今后的找煤与勘探工作中,采用综合勘探技术对厚煤层变薄及缺失和基底构造形态予以精确控制,是满足高产高效矿井对地质条件精度要求的必要。Based on large number of drilling data in Binchang and Linbei preliminary exploration areas, after evaluation and analysis of integrated exploration results, the authors considered： there are coexisted paleotopographic uplifts and depressions in basement controlled by paleostructures. Thus influenced coal accumulating to a great extent and has obvious regularity. Ceaseless silting and compensating in adjacent two rivers, extra-thick coal seams formed in depressed topographic lows annularly, and the main control factor of the extra-thick coal seam forming was favorable combination of tectonism. In the future coal seeking and exploration, the use of integrated exploration technique to find out thinning and hiatus of thick coal seams and accuracy control of basement structural features is essential to satisfy geological accuracy specifications for high yield and high efficiency coal mines.
