摘要
江苏句容市矽锅顶水泥灰岩矿是大型灰岩矿床,可利用灰岩矿石量在2亿t以上。该文对矽锅顶灰岩矿现有的开采技术条件进行总结和评价,划分了水文地质单元,以封闭-半封闭盆地模型计算矿区涌水量,认为矿区水文地质条件为中等类型;对矿体及围岩的稳固性进行了评价,并对矿区地质灾害隐患进行了分析总结,认为矿区工程地质条件为中等类型;对矿区污染物及对环境造成的影响进行了说明,认为矿区环境地质条件属中等类型,综合考虑本矿床开采技术条件复杂程度综合类型为Ⅱ类。同时该文依据已有资料并对未来的水文地质、工程地质和环境地质条件进行了分析预测。
This paper summarizes and evaluates the existing mining technical conditions of Xiguoding limestone mine,divides the hydrogeological units,calculates the mining area's water discharge with the closed-semi-closed basin model,and considers that the hydrogeological conditions of the mining area are of medium type.The stability of ore body and surrounding rock is evaluated,and the hidden danger of geological disaster in mining area is analyzed and summarized.It is considered that the engineering geological con⁃dition of mining area is medium type.It is considered that the environmental geological conditions in the mining area belong to the medi⁃um type.Considering this type of deposit mining technical conditions complexity forⅡtype.At the same time,the hydrogeology,engi⁃neering geology and environmental geology conditions in the future are analyzed and predicted based on the available data.
