依据王家岭煤矿中奥陶统峰峰组岩性特征及采样分析结果,把该组划分为四个层段:风化淋滤段、上部含石膏段、厚层泥晶灰岩段和下部含膏岩段。在分析该区水文孔抽水试验和岩样溶蚀实验结果的基础上,结合区域的水文地质特征、构造特点、岩性等方面情况,分段分析了峰峰组的隔水特性,分析认为:风化淋滤段、上部含石膏段和厚层泥晶灰岩段隔水能力较弱,下部含膏岩段隔水能力很强。分析结果对开采太原组煤层有一定的参考价值。
Based on the lithological characteristics and sampling analysis results of the Middle Ordovician Fengfeng Formation in the Wangjialing Coal Mine, the group is divided into four intervals: weathered leaching section, gypsum section in the upper part, thick smectic limestone section in the upper part and gypsum rock section in the lower part . Based on the analysis of hydrology hole pumping test and rock erosion test result in this area, combining with the hydrogeological characteristics, structural characteristics and lithology of the area, The leaching section, the gypsum section with the upper part and the thick mudstone with limestone section have weak water-proofing ability, and the gypsum-bearing rock section with lower water-proofing ability is very strong. The results of the analysis have certain reference value for the mining of Taiyuan coal seam.
