在毛主席革命路线的指引下,为了加速邯邢矿山建设,第一井巷公司广大职工在北洺河铁矿竖井施工中,坚持独立自主、自力更生的精神,在设备和材料一时供不应求的情况下,因陋就简,与东北工学院师生一道,在竖井掘进中创造出一种大抓斗双直轨式施工方法,进行竖井井颈部分施工。它具有结构简单,易于加工制作,机械化程度高,劳动强度低,成井速度快等特点。仅在3个月的时间内,就陆续开掘了三条竖井,除完成施工前大量准备工作外还掘进81.3米,纯掘进时间为77天,平均月成井31.7
Under the guidance of Chairman Mao’s revolutionary line, in order to accelerate the construction of Handan Mine, the majority of staff and workers of First Well Lane, in the construction of shafts at Beidaihe Iron Mine, insisted on the spirit of independence and self-reliance, with short supply of equipment and materials, Because of its simplicity, together with teachers and students from Northeastern Institute of Technology, we have created a kind of big grab double straight track construction method in the shaft excavation to carry out the construction of the shaft and the neck of the shaft. It has a simple structure, easy processing, high degree of mechanization, low labor intensity, speed and other characteristics into well. In just three months, three shafts were drilled one by one. In addition to completing a large amount of preparatory work prior to construction, 81.3 meters of tunneling was carried out. The time for pure excavation was 77 days and the average monthly well completion was 31.7
