云锡公司松树脚锡矿自一九七六年以来,积极推广应用由本公司研究所矿山室设计,机修厂制造的TZ—1200型全液压,全断面天井钻机新设备,结合矿山生产进行扩大性试验,到一九八四年止,共为矿山生产钻凿了直径分别为1.2米和1.5米的中深天井八口,累计总进尺532米,其中最深的一口为120米,直径1.5米。这个矿根据生产的需要,利用该型全液压全断面天井钻机,于今年元月二十八日,又较顺利地凿通了一口直径为1.2米,井深为175米的高深坑下天井,成井速度1.1米/台班。从而刷新了全国有色
Since its establishment in 1976, the company has actively promoted the use of the new TZ-1200 full-hydraulic and full-face well drilling rig manufactured by the Company’s research institute mine room design and mechanic factory, and expanded its production in combination with mine production Test. By 1984, a total of eight medium and deep pavements, 1.2 and 1.5 meters in diameter, were drilled for mine production. The total footage footage was 532 meters. The deepest one was 120 meters and the diameter was 1.5 meters. According to the needs of production, the mine harnessed a well with a depth of 175 meters under a deep pit on January 28 this year using the fully hydraulic full-face well drilling rig. Speed of 1.1 meters / Taiwan class. Thus refreshing the national non-ferrous
