【摘要】 基于刘桥一矿已完工注浆改造工作面底板成孔与注浆信息,在分析太原组灰岩岩性与岩溶发育特征的基础上,统计工作面底板太灰含水层出水量与注浆量,得出钻孔出水量与注浆量呈正相关关系。综合选取钻窝单孔最大出水量和单位体积注浆量两个指标,将太灰上段岩溶含水层岩溶结构划分为四种类型,并分析各结构类型在矿井内的分布状况,为进一步评价注浆效果和指导防治水工作提供基础。更多还原

【Abstract】 Water yield and grouting quantity were obtained on the data of floor pore-forming and grouting of the working face where grouting reconstruction has finished in Liuqiao No.1 Mine and on the analysis of Taiyuan formation limestone features and karst aquifer development features. The calculation obtains a positive correlation between the water yield and grouting quantity. The maximum water yield of a single pore and the grouting quantity of unit volume were selected to classify the karst aquifer into 4 types.The distribution of the different structure types could provide a basis for further evaluation of the grouting effect and water control.更多还原
