摘　　要：分析了采空区带来的安全隐患和主要危害,总结了当前采空区探测中使用的主要方法和手段.针对厂坝铅锌矿存在大量复杂群采空区的情况,提出了以探地雷达和瑞雷波法为主的综合探测技术.介绍了2种物探方法的基本原理和技术特点.探测结果表明,综合物探方法提高了采空区探测的准确度和精度,基本查明了群采空区的层位、分布、范围和贯通关系,为矿山由露天开采转入地下生产提供了安全保障条件.图5,表2,参11.Safety hidden trouble and main hazards brought by mined -out areas were analyzed, and main methods and means used in detecting mined - out areas currently were summarized. For complicated associated group mined - out areas exist at Changba Lead -zinc Mine, composite detecting technology with generating ground radar and Raleigh wave method is taken forward. The principle of two geophysical mehods and technical characters were introduced. Results show that composite geophysical methods increase the accuracy and precision of mined -out areas detection, and position, distribution and transfixion relationship of group mined -out areas are found out basically, which can offer security guarantee condition when opening working turns to underground working in the mine. 5figs. ,2tabs. , 11 refs.
