我們对轻型山地工程水平探矿巷道的打眼作业,由于工程分散、工期较短、断面窄小等原因,长期採用人工打眼,这不仅是繁重的体力劳动,同时效率不高,掘进速度較慢,工期要长,在硬岩石和小断面条件下尤甚。为此,寻求适应我們工程技术条件,改革打眼工具,从而达到減輕体力劳动、提高凿岩效率的問題就摆在我們的面前。 1958年在全面跃进的偉大形势推动下,为了滿足加快地質勘探速度的要求,我分队党委对山地工程提出了攻破水平巷道掘进中劳动强效率低的人工打眼这
Our drilling work on the level roadway of light mountainous engineering exploration has long-term use of manual drilling because of decentralized projects, short construction schedules, and narrow sections. This is not only arduous physical labor, but also has low efficiency and slow tunneling. Longer, especially in hard rock and small sections. To this end, it is in front of us to seek to adapt to our engineering and technical conditions, and to reform our strike tools so as to reduce physical labor and improve rock-drilling efficiency. In 1958, under the impetus of the great leap forward, in order to meet the requirement of accelerating the speed of geological exploration, the party committee of our team proposed to the mountainous engineering project to artificially break the level of labor intensity in roadway tunneling.
