| 摘 要： | 井田构造复杂程度和煤层稳定程度是影响勘探基本工程线距选择的主要因素.依据构造和煤层的等性块段划分和赋值原则,以及井田构造复杂程度与煤层稳定程度的确定原则,综合考虑了断层,褶皱分布特征和煤层厚度、可采范围、零点等因素,将宁夏灵武煤田碎石并矿区羊场湾井田划分为若干等性块段,并分别赋值.结果显示,该井田各主要煤层的构造指数平均为0.29,各主要可采煤层指教平均为0.7,进而确定该井田构造简单、煤层稳定.

| Abstract: | The complicated degree of structures and stability of coal seam is the main factor impacting the basic engineering lines layout.The Yangchangwan mine-field of Lingwu coal field,Lingxia was divided into several blocks of identical characters and assigned individually according to identification principles of structure and coal seam,assignment regularity as well as complicated degree of structure and stability of coal seam.The analysis re-sults showed that the mean structural index of main coal seams in this ... |
