山东省平邑县唐家崖石膏矿区东段水文地质特征分析

Analysis on Hydrogeological Characteristics in Eastern Section of Tangjiaya Mine in Pingyi County of Shandong Province

摘要:

唐家崖矿区地处平邑凹陷的中偏西南部，石膏矿床为一中型内陆湖相沉积矿床。该文分析了矿床的水文地质条件和含水岩组及隔水岩组的含水特征。通过对充水因素的分析，根据边界条件确定了水文地质模型，选取了大井法预测矿坑的涌水量。并在此基础上确定了矿区的水文地质条件属中等类型。

Abstract:

Tangjiaya mine locates in the southwest part of Pingyi depression. Gypsum deposit is a medium-sized inland lacustrine sedimentary deposit. Hydrogeological conditions of the deposit, water bearing rocks and water bearing characteristics of water resisting rocks have been analyzed in this paper. Through analysis on water filling factors, hydrogeological model has been determined by the boundary conditions, and water inflow of the mine has been predicated by using big well method. On these basis, hydrogeological conditions of the mine area are determined to be medium type.
