| 摘 要： | 汝州煤田牛庄井田断裂构造较发育，主采煤层二1煤厚度变化大，根据经验无法准确的确定井田勘查类型。采用等性块段指数法对煤层等性块段和构造等性块段进行科学、合理的赋值，将计算得出的煤层总指数和构造总指数与勘查类型划分标准进行对比，据此得出牛庄井田构造复杂程度为复杂构造、二1煤为不稳定煤层。

| Abstract: | Normal and reversed faults are all rather developed in the Niuzhuang minefield, Ruzhou coalfield. The thickness of main mineable coal seam Ⅱ 1 is variable, thus the exploration type of minefield can not be definitized according to foregone experiences. Using iso-functional block-section carries out coal seam and structure iso-functional block-section assignments scientifically and rationally. Contrasted coal and structure general indices and division standard of exploration type, on these grounds have definitized the minefield＇s structural complexity is structurally complex; and coal seam Ⅱ 1 an unsteady coal seam. |
