为了配合汶川地震科学深钻，弄清楚钻孔附近浅层的断层面结构，中国地震局地球物理研究所分别在四川省绵竹市天池乡和四川省绵阳市南坝镇布设了15套南非矿山地震研究所(IMS)生产的矿山地震仪。本文分析了矿山地震仪用于天然微震监测中仪器布设、数据采集和数据处理等方面遇到的问题，介绍了与这种仪器对应的数据的文件格式，并实现了该数据与通用地震数据格式SAC二进制格式的转换。

In order to cooperate with the Wenchuan fault scientific drilling (WFSD) program and understand the shape of the shallow faults near the boreholes, 15 mine seismographs produced by Institute of Mine Seismology (IMS) in Africa were deployed in Tianchi township, Mianzhu city and Nanba township, Mianyang city , Sichuan Province, respectively. Because it was the first time for us to use mine seismographs to detect natural microearthquakes, we encountered some problems in layout of stations, data collection and data processing. Finally we introduced the data format corresponding to these mine seismographs and converted this format to SAC binary format successfully.
