1958年我队在坑探生产大跃进中取得了巨大的成绩,综合平均台班工效由56年的1.1公尺上升到1.8公尺,较56年提高了78%,较57年提高了76%。各类坑道也较57年有了显著的提高,平巷工效提高43%,天井工效提高61%,盲井提高66%,斜井约提高了一倍。全年平均工效平巷达1.9公尺,天井达2.2公尺,盲井达1.25公尺。最高冷风硐平均工效达2.78米。坑探技术水平大大向前推进了一步。这主要是在党的正确领导下,经过伟大的整风运动后,职工们的社会主义觉悟大大提高,树立了主人翁的态度,劳动热情空前高涨,积极开动脑筋找窍门,想办法改进了七眼直线掏槽爆破操作技术,減少了空枪、瞎炮,提高了爆破效率。 In 1958, our team made great achievements in the great leap forward of pit exploration. The average work efficiency of the integrated platform increased from 1.1 meters to 1.8 meters in 56 years, an increase of 78% over 56 years and an increase of 76% over 57 years. . Various kinds of tunnels have also been significantly improved over the 57 years. The work efficiency of the roadway has been increased by 43%, the efficiency of the patio has been increased by 61%, that of the blinds has increased by 66% and that of the inclined shafts has been doubled. In the whole year, the average working efficiency roadway reached 1.9 meters, the patio reached 2.2 meters and the blind reached 1.25 meters. The average maximum effective cold air hole 2.78 meters. Pit exploration technology has greatly advanced the level of a step forward. This is mainly under the correct leadership of the party. After a great rectification campaign, the workers’ social awareness has been greatly enhanced and their ownership has been mastered. Their enthusiasm for work has been on an all-time high and their brains are being actively explored. They have tried their best to improve the seven-eye straight line Cutting blasting operation technology, reducing the air gun, blind artillery, improved blasting efficiency.
