摘要
为了给祁雨沟公峪金矿进一步勘探开发提供依据,有效保护矿山地质环境,促进矿业经济持续、健康发展,研究了祁雨沟公峪金矿水文、工程、环境地质条件。研究得出,矿区位于区域地下水径流、排泄区,含水层主要有3类,水文地质条件总体较简单,受含水层透水性影响,矿区地下水与地表水联系联系微弱;根据矿区内各类岩土体工程地质特征,将其划分为4类工程地质岩组,大部分区域表层岩土体风化强烈,较为破碎,但深部岩体完整性较好,工程地质条件较好,矿区范围内地层分布稳定、承载力高,有利于主副井工程辅助设施的建设;研究区仅发现1处地面塌陷,没有发生较大的崩塌、滑坡、泥石流、地裂缝等自然地质灾害,矿山环境地质条件复杂程度分级为中等。结合矿区地形地貌、工程地质、水文地质、环境地质条件,评估区其他区地质灾害危险性小,评估区采矿活动对含水层影响程度较轻。研究表明,矿床复杂程度的综合类型为二类一型,属开采技术条件简单的矿床。
In order to provide a basis for further exploration and development of Qiyugou Gongyu Gold Mine,effectively protect the geological environment of the mine,and promote the sustainable and healthy development of the mining economy,this paper studies the hydrological,engineering and environmental geological conditions of Qiyugou Gongyu Gold Mine.The study concluded that the mining area is located in the regional groundwater runoff and discharge area.There are mainly three types of aquifers.The hydrogeological conditions are generally relatively simple.Due to the influence of the water permeability of the aquifer,the connection between the groundwater and surface water in the mining area is weak.According to the engineering geological characteristics,it is divided into four types of engineering geological rock groups,most of the surface rock and soil mass is strongly weathered and relatively broken,but the deep rock mass has good integrity,good engineering geological conditions,and stable strata distribution in the mining area,high bearing capacity,which is conducive to the construction of auxiliary facilities for the main and auxiliary shaft engineering.Only one ground subsidence was found in the research area,and no natural geological disasters such as major collapse,landslide,debris flow,and ground fissure occurred.The complexity of environmental geological conditions is classified as medium.Combined with the topography,engineering geology,hydrogeology,and environmental geological conditions of the mining area,the risk of geological disasters in other areas of the assessment area is small,and the impact of mining activities on the aquifer in the assessment area is relatively light.Therefore,the comprehensive type of the complexity of the deposit is classⅡtypeⅠ,which is a deposit with simple mining technical conditions.
