沉积特征与聚煤规律研究在煤矿开采中的应用——以黄陇侏罗纪煤田郭家河煤矿为例
|
摘要
通过收集、对比煤矿勘查、建井和生产资料,开展含煤地层沉积特征和沉积环境的分析研究,对岩相古地理格局进行恢复。在此基础上,结合煤层发育及赋存特征,总结其聚煤规律,并与矿井实际生产数据进行对比分析。研究结果表明:郭家河煤矿大部分地区发育河漫沼泽相沉积;东部发育河漫滩相沉积;中部地区的古洼地水体较深,发育河漫湖泊相沉积;在古隆起与河漫沼泽过渡区域发育冲积带沉积;煤层发育与含煤地层沉积呈正相关性,地层发育厚煤层亦厚,地层发育薄煤层亦薄甚至尖灭。区内可划分为三个含煤地带:富煤带(厚煤区)、稳定聚煤区和含煤过渡带,其中富煤带煤层最厚最好,含煤过渡带煤层最薄最差。通过与矿井工作面生产实际对比综合分析后,预测在矿井二盘区南部、北部位于古隆起的"山脊"处的含煤过渡带,煤层薄且变化大,采区工作面出现"孤岛状"无煤区的可能性较大。
Through coalmine exploration,construction and production data collection and comparison,have carried out analytical study on coal-bearing strata features and sedimentary environment,restored lithofacies and paleogeographic pattern. On this basis,combined with coal seam development and hosting features,summarized coal accumulation pattern,than carried out contrastive analysis with coalmine actual production data. The result has shown that in most area of the Guojiahe coalmine had been developed flood plain swamp facies sediments; eastern part flood plain sediments; middle part ancient low-lying land with deeper water bodies and developed flood plain and lacustrine facies sediments; in old heaving and flood plain swamp transitional area developed alluvial zone sediments. Coal seam development and coal-bearing strata present positive correlation: the thick the strata,the thick the coal seam,vice versa,even coal seam thinning out. In the area,3 coal-bearing zones can be partitioned: coal rich zone( coal thick area),steady coal accumulation zone and coal-bearing transition zone. In which,the coal rich zone has thickest and best coal seams,while the coal-bearing transition zone has thinnest and worst coal seams. Through coalmine working face production actual data correlation and comprehensive analysis,have predicted in coal-bearing transition zone,i. e. south and north part of the coalmine panel No. 2 had been on an old heaving"mountain ridge",coal seams thin and varied,possibility of working area"isolated island shaped"barren area is large.
