| 摘 要： | 鸡西煤田面临严峻的资源接替问题。以煤田探采、地震及野外勘查资料为基础,对区内煤层分布规律,盆地构造演化对煤层聚集与改造的控制作用及找煤方向进行了研究。分析认为：城子河组煤层的聚集和保存受箕状断陷的形成和演化影响较大;平面上南北两个向斜的北翼和盆地东部是煤层聚集和保存较好的区域;剖面上城子河组可采煤层主要发育于该组中下部的低水位体系域和水进体系域;位于区内南部向斜北翼的玄武岩覆盖区域有较好的煤层保存。 |

| Abstract: | The Jixi coalfield is now facing a serious resource succession issue.Based on coalfield exploration and mining information,seismic prospecting data and field investigation information,analyzed coal seam distributing pattern,basin structural evolution controlling on coal seam accumulation and modification,as well as coal looking orientation.The analysis considered that the accumulation and preservation of coal seams in the Chengzihe Formation are largely impacted by the formation and evolution of dustpan-like fault depression.In plane view,north limbs of south and north two synclines and eastern part of the basin are better coal seam accumulation and preservation areas.In profile,the mineable coal seams in Chengzihe Formation are mainly developed in middle and lower part lowstand systems tract and transgressive systems tract.The north limb basalt covering area of the south syncline has better preservation of coal seams in Chengzihe Formation. |
