建设项目压覆矿产资源储量技术方法研究——以南水北调中线一期工程总干渠为例

Study on Technical Methods of Mineral Resources Reserves below Constructed Projects——Taking the Main Channel of Middle Line of South-to-North Water Transfer Project for Example

首先对建设项目压覆矿产进行了分类,提出了压覆矿产的理论依据,并根据地质条件、岩石类型及力学特征、采矿技术等对压覆矿产资源储量技术方法进行了研究,提出露采边坡角和地下开采移动角的确定方法,提出了建设项目压覆范围确定方法和压覆范围内资源储量估算参数选取及估算方法,并应用于南水北调一期总干渠压覆核查中,结果表明,该方法是可靠、可行的.

The paper firstly makes a classification of mineral resources below constructed projects,and then offers its theoretical basis,finally studies technical methods of mineral resources reserves below constructed projects according to the geological condition,rock type,mechanical characteristic,mining technology and so on. Mean- while,it gives two determination methods of the slope angle at the open pit and underground mining displacement angle,and brings forward determination methods of extent of mineral resources below constructed projects as well as the methods of parameter selection and calculation of overlaid reserves. The above-mentioned methods have been used in overlaid reserves check of the main channel of the middle line of South-to-North Water transfer project. It shows they are reliable and feasible.
