焦家金矿深部多头贯通测量

Deep multiple connect survey in Jiaojia Gold Mine

焦家金矿主竖井深 380m ,设计开拓八个中段 ,六个中段的采矿已接近尾声 ,需进行深部七、八两个中段的开拓 ,为了不影响生产 ,确定的开拓方案非常复杂 ,贯通测量难度大。在整个贯通测量中 ,采用了合理的联系测量方案 ,使用了陀螺仪、全站仪、激光指向仪等测量先进仪器 ,使工程顺利贯通。

The main vertical shaft is 380 meters deep in Jiaojia Gold Mine,and it has eight level.Six level almost finished mining,so the rest two level need to be developed.In order to avoid the influence on production,the development plan is very complex,and the connect survey is difficult.Since suitable connection survey plan which used gyroscope,electrode total station and laser guide instrument had been adopted,the connect work have been finished successfully.
