【摘要】 邙岭预查区位于河南省偃龙煤田西北部找煤区深部,其西部的"平乐预查区"和东部的"巩义预查区"均有钻孔揭露可采二1煤层。从成煤地质环境分析,夹在这两预查区中间的邙岭预查区也应该存在可采的二1煤层,但经钻探,该预查区施工两孔均缺失二1煤层,只有29-1孔揭露了一1可采煤层。对沉积环境、区域构造、地层、岩性特征、二维地震及周边情况进行分析,得出结论:区内存在二1煤层。对该区煤炭资源潜力进行评价,认为该区主要可采煤层为二1、一1煤层,预测的内蕴经济资源总资源量为15 929万t。更多还原

【Abstract】 Mangling prediction area lies in deep part of northwestern coal-searching area of Yanlong Mine Field in Henan Province,and the boreholes in western "Pingle prediction area" and in the eastern "Gongyi prediction area" have uncovered Ⅱ1 coal seam.Through the analysis on the coal geological environment,the authors inferred that Mangling prediction area between these areas may contain Ⅱ1 coal seam.But the two boreholes constructed in the prediction area have missed Ⅱ1 coal seam,and only 29-1 borehole has exposed mineable Ⅰ1 coal seam.Five aspects were analysed in this paper,including sedimentary environment,regional structure,formation,lithology,seismic and surrounding situation,then the conclusion was drawn that,the mineable coal seams are Ⅰ1 and Ⅱ1 coal seam,the whole expected resource is 159.29 Mt.更多还原
