【摘要】 探地雷达基于所探介质的电性差异对其内部不可见目标体或介质分界面进行精确辨别定位,其对不良地质体的准确预警可有效减少矿山井巷工程中的突发事故。采用EK-KO-100型探地雷达在播卡金矿进行了岩层含水量、围岩破碎程度、老硐及采空区定位等现场探测工作,安全高效指导井巷施工的同时验证此法具有广泛推广应用价值。探地雷达在播卡金矿井巷工程超前预报中的实际应用,对播卡金矿的矿山安全生产监督管理,防止和减少生产安全事故有着十分重要的意义。更多还原

【Abstract】 On the basis of electrical property difference of probed object,GPR could make invisible target or interfaces of media inside accurately positioned and distinguished,the exact early warning about defective geology body would be very effective in reducing sudden accident in mine tunnel.In Boka gold mine,investigation on water content,rock integrity,positioning old tunnel or ancient goaf and other fieldwork were taken with EKKO-100 GPR,the result shows that laneway construction was carried out safely and efficiently and demonstrates that this method can be widespread.Practical application of ground penetrating radar in advanced forecast of Boka gold mine tunnel has very important meanings for supervising and managing the safety in mine production,preventing and reducing accidents during the production process.更多还原
