为掌握金海洋矿区煤层多、厚度变化大的煤层展布规律,通过对矿区276个钻孔测井、岩心资料分析并进行粒度统计和元素测试,结果表明:该矿区主要发育障壁海岸、浅水三角洲和河流湖泊3种沉积体系,障壁岛、泻湖、潮坪、沼泽、三角洲、河流、湖泊7种沉积相类型,相带南北分异、东西展布;成煤期间多次海侵,受此影响,9号、11号煤发育连续,煤层测井高峰窄频峰值较多,夹矸数一般大于4,其他煤层发育不稳定,尖灭缺失;11号煤西厚东薄、北厚南薄,均厚3.69 m,9号煤西薄东厚,东部分叉,均厚6.78 m;太原组煤中V、Mn、U、P、Fe、S等元素含量均比山西组高,与沉积相展布相适应。

In order to analyze the seam distribution law with multi seams and thickness variation in Jinhaiyang Mining Area, there were 276 borehole loggings and C ore information of the mining area analyzed and the particle statistics and the element measurement were conducted.The results showed that there were three sedimen tary systems mainly including the developed barrier coast, shallow water delta, river and lakes in the mining area.There were seven sedimentary facies types of the barr ier islands, lagoon, tidal flat, marsh, delta, river and lakes. The facies belt was different in north and south and was expanded and distributed in east and west.During th e coal formation period, several transgressions were occurred.Due to the influences, No.9 and No. 11 seams were developed continuously and high peaks and narrow fr equency peaks were occurred many times in the seam loggings.There were over 4 partings generally occurred in the seams.Other seams were developed unstable and pinched out or lost.As for No.11 seam, the west part would be thick and the east part would be thin, the north part would be thick and the south part would be thin, and t he average thickness would be 3.69 m.As for No.9 seam, the west part would be thin and the east part would be thick, the east seam would be forked and the average t hickness of No.9 seam would be 6.78 m.In the Taiyuan Formation, V, Mn, U, P, Fe, S and other elements content of the coal would be higher than Shanxi Formation and would be similar to the sedimentary facies in expansion and distribution.
