辽宁红阳煤田控煤构造与深部煤炭资源潜力

Structures controlling coal and deep coal resource potential in Hongyang coal field, Liaoning

  • 摘要: 针对辽宁红阳煤田局部采区浅部煤炭资源逐渐枯竭的问题,通过煤田构造发育规律和演化史研究、油气地震勘探资料解译、平衡剖面恢复等技术和方法,预测了该煤田深部及外围煤炭资源的赋存状况、远景勘探开发区及煤炭资源量。结果显示:煤田二区为正常背斜的控煤构造,-1500m以浅的煤炭资源储量为83148万t;煤田南部岳家堡背斜往南发育,徐往子勘探区东部存在一个低次序含煤向、背斜构造,可作为远景勘探区,估算-1500m以浅的煤炭资源量为1.85亿t。

     

    Abstract: Aimed at exhaustion of shallow coal resources of local mining district in Hongyang coal field in Liaoning Province, through study of development regularities of structure and evolution history in the coal field, interpretation of oil and gas seismic exploration data, recovery of balanced section and other techniques and methods, the paper predicted the occurrence of coal resources in great depth and peripheral areas of the coal field, prospective areas for exploration and development as well as amount of coal resources.The second district of the coal field is a normal anticline, a structure controlling coal, the coal reserves at depth less than -1500m are 83148×104 t.in the south of the coal field, Yuejiabao anticline is developed southward.In the east of Xuwangzi exploration area, there are anticline and syncline of lower order, which can be considered as a prospective exploration area, the estimated coal resources at depth less than -1500m are 18500×104 t.
