由赤峰有色金属矿山钻机修造厂研制的ZSK—50型坑内采场地质探矿钻机,已经通过技术鉴定,并将投入批量生产。样机于1984年研制成功后,分别送往江西小龙钨矿和湖南锡矿山矿务局进行生产性试验。梧桐花铅锌矿和冯家山铜矿结合生产的需要,也用样机进行了部分生产钻孔试验。这四个矿山两年来共计完成62个钻孔,总进尺2183.5米,其中深度超过50米的钻孔有9个,最深的孔57米。
The ZSK-50 pit internal mining prospecting rig developed by Chifeng Non-ferrous Metal Mine Rig Repair Factory has passed the technical appraisal and will be put into mass production. After the prototype was successfully developed in 1984, it was sent to Jiangxi Xiaolong Tungsten Mine and Hunan Xikuang Mine Bureau for production test. Indus Tonghua lead-zinc mine and Feng Jiashan copper production needs, but also with the prototype part of the production drilling test. The four mines completed a total of 62 boreholes over the past two years, with a total footage of 2183.5 meters, of which 9 boreholes deeper than 50 meters and 57 meters deep.
