1987年我局探矿工作取得的成绩较显著,各项技术经济指标比1986年有新的提高.全局预算内完成钻探工作量81911米,为年计划的119.81%,平均台月效率640米,比1986年提高137米;纯钻进时间利用率42.85%,比1986年提高6.88%;优质孔率达95.82%;比1986年提高8.92%.这是因为我局认真贯彻了1986年部探矿工程工作会议精
In 1987, the results obtained by the Bureau of Mine Exploration were significant, and the technical and economic indicators were newly increased compared with 1986. The overall budget for drilling work was 81,911 meters, which was 119.81% of the annual plan, and the average monthly efficiency was 640 meters. In 1986, it was increased by 137 meters; the utilization rate of pure drilling was 42.85%, which was 6.88% higher than that in 1986; the high-quality hole rate was 95.82%; and it was 8.92% higher than that in 1986. This is because the Bureau carefully implemented the 1986 exploration engineering work. Conference fine
