介绍KQS 150型露天潜孔钻机的主要性能和结构特点,以及在石灰石矿工业试验的结果。为满足我国中小型矿山推广大孔径高梯段穿爆新工艺(钻机的利用率可提高15～20％)的迫切需要,我厂研制成功KQS 150型露天潜孔钻机(图1)。该机已通过省级鉴定,截止1987年3月已出厂17台。 Describe the main performance and structural features of the KQS 150 open pit driller, as well as the results of the limestone mining industry test. In order to meet the urgent need of small and medium-sized mines to promote the new technology of wearing large-aperture high-pitches (the utilization rate of drilling machines can be increased by 15-20%), our factory successfully developed the KQS 150 open-air and down-hole drilling machine (Figure 1). The machine has passed the provincial appraisal, as of March 1987 has 17 factory shipped.
