摘　　要：煤矿是豫北安阳地区重要的优质矿产资源,为进一步做好煤炭建设远景规划,需对该区煤炭资源的经济意义及开发建设可行性进行评价。豫北内黄煤矿位于华北板块内西南端内黄隆起与东明凹陷的交汇北部。区内地质构造复杂,主要表现为褶曲多、断层较发育、煤层连续性差,煤矿勘查评价难度较大。采用单一的钻探方式难以查明煤层分布情况,通过二维地震连续剖面勘探,对煤层进行追踪、确定断裂位置、圈定煤层分布区块等,并进行钻探验证。快速、高效查明该区新生界覆盖层的厚度、地层构造大致情况,二_(1)煤底板埋深埋深2000 m以浅的面积共有232.22 km^(2),资源潜力巨大。研究为豫北矿产资源规划提供内黄煤矿的详细资料。Coal mine is an important high-quality mineral resource in Anyang area of north of Henan.In order to further make a long-term plan for coal construction,it is necessary to evaluate the economic significance and development and construction feasibility of coal resources in this area.Neihuang Coal Mine in north of Henan is located in the north of the intersection of Neihuang uplift and Dongming depression at the southwest end of the North China plate.The geological structure in the area is complex,which is mainly manifested in many folds,relatively developed faults and poor continuity of coal seams.It is difficult to explore and evaluate coal mines.It is difficult to find out the distribution of coal seams by using a single drilling method.Through two-dimensional seismic continuous profile exploration,the coal seams are tracked,the fault location is determined,the coal seam distribution block is delineated,and the drilling verification is carried out.Quickly and efficiently find out the thickness of the Cenozoic overburden and the general situation of the formation structure in this area.There are 232.22 km^(2) in the area with a buried depth of more than 2000 m in the floor of Ⅱ_(1) coal seam,which has great potential for depth resources.The study provides detailed information of Neihuang Coal Mine for the planning of mineral resources in north of Henan.
