我队去年8月在雅满苏铁矿开始试用绳钻,打了一个558米的试验孔,取得了台月效率、钻头进尺、时间利用率等各项技术经济指标均超过同矿区普通金刚石钻进的较好成绩;试验孔综合台月效率485米,绳钻台月效率671米,钻头平均进尺75.64米,最高钻头进尺176.31米,共投入6个钻头,超百米钻头2个。今年,又开动了绳钻两台,自去年8月到今年6月底止,我队共开动绳钻4.63台月完孔5个,绳钻总进尺2205.95米,平均台月效率476米,各项技术经济指标都高于普通金刚石钻进,初步体现了绳钻的优越性,机台工人满意地说:“过去取心满头汗,如今取心真清闲”。对巩固钻探队伍起到积极作用。
In August last year, our team experimented with ropes at the Yaman Cycas mine and hit a 558-meter test hole to obtain the technical and economic indicators such as the efficiency of Taiwan and Taiwan, footage entry and time utilization, all surpassing the ordinary diamond drill The test bench integrated typhoon efficiency of 485 meters, 671 meters of rope drill on a month efficiency, average drill bit 75.64 meters, the maximum drill footage into 176.31 meters, a total investment of six drill bits, two hundred meters over 100 meters. This year, we started two ropes again. From last August to the end of June this year, our team started a total of 5 pieces of rope drilling 4.63 sets per month. The total drilling rope penetration was 2205.95 meters with an average efficiency of 476 meters per month. Technical and economic indicators are higher than ordinary diamond drilling, the initial embodiment of the superiority of rope drilling, machine workers said with satisfaction: “In the past corrupted sweat, now cautiously idle ”. To consolidate the drilling team play a positive role.
