摘要
为了进一步了解河南省内黄煤普查区煤层分布概况,研究了河南省内黄煤普查区地质及煤层特征,采用先二维地震后钻探,配合数字测井、测试化验等手段相结合的综合勘查方法,研究了普查区地质特征(主要为地层、构造、岩浆岩等特征),得到了构造复杂程度以及控制可能影响矿区划分的主要构造;分析了煤层主要含煤地层,含煤性,可采煤层厚道、夹矸、分布范围以及煤岩层对比情况等,大致确定了可采煤层煤类特征以及可采煤层的稳定程度。研究为煤炭工业的远景规划和下一阶段的勘查工作提供必要的资料。
In order to further understand the general situation of coal seam distribution in the Neihuang Coal Survey Area in Henan Province,this paper studied the geology and coal seam characteristics of the Neihuang Coal Survey Area in Henan Province,using a combination of two-dimensional seismic first,followed by drilling,and digital logging,testing and testing.Comprehensive exploration methods,research the geological characteristics of the general survey area,mainly stratum,structure,magmatic rock,etc.,obtain the structural complexity and control the main structures that may affect the division of the mining area;analyze the main coal-bearing strata of the coal seam,and the coal-bearing property,the minable thickness of the coal seam,the inclusion of gangue,the distribution range and the comparison of the coal and rock layers,etc.,roughly determine the characteristics of the coal seams and the stability of the coal seams.The study provides necessary information for the long-term planning of the coal industry and the next stage of exploration work.
