我们从1972年4月开始使用地勘工型装岩机,到1974年底,共掘进坑道2259.6米,装碴36,000余车,平均台月效率294米。今年在批林批孔运动的推动下,几个月未发生故障,完全甩掉了用扒子、铁箕装车的落后面貌,实现了装碴机械化。实践证明:地勘Ⅰ型装岩机具有功率小、重量轻、体积小、好操作、可拆性强的特点,适应探矿坑道的要求,是节省劳力、减轻劳动强度、组织快速掘进、促进生产发展的较好设备之一。三年来,我们在队党委
Since April 1972, we started to use geotechnical rock drilling machines. By the end of 1974, we had dug 2259.6 meters of ditches and over 36,000 ballast tanks with an average efficiency of 294 meters per month. This year, thanks to the pro-Lin campaign, a few months did not break down, completely abandoning the backwardness of loading with a pick-up truck and an iron-pan and realizing the mechanization of loading ballast. Practice has proved that: Geological Prospect Ⅰ type rock loader with small power, light weight, small size, good operation, removable and strong features to meet the requirements of prospecting tunnel is to save labor, reduce labor intensity, organize rapid excavation and promote production One of the better equipment to develop. In three years, we are party team
