| 摘 要： | 中奥陶统碳酸盐岩是华北型煤田开采下部煤层的主要充水含水层.为开采深部煤炭,对山西阳泉矿区峰峰组碳酸盐岩进行偏光显微镜、扫描电镜、全应力一应变下的渗透性试验研究,分析了不同岩性沉积岩石的应变-渗透率试验曲线,阐述了不同岩性岩石在变形破坏过程中渗透性变化的规律,得出岩石的一般应变一渗透曲线.研究表明,岩石的应变-渗透率曲线是岩性、结构、应力状态等各种影响因素综合反映的结果,该煤田峰峰组碳酸盐岩可作为隔水层或相对隔水层.

| Abstract: | The Middle Ordovician carbonatite is the main water filled aquifer under the mining seam of North China Coalfield. In order to excavate the deep coal resources, a research on the permeability test was conducted on the carbonatite in Fengfeng Group of North China type coalfield with polarizing microscope and scan electronic microscope (SEM) under the full stress and strain. The paper analyzed the stress permeability test curve of the different sedimentary rocks. The paper stated the permeability variation la... |
