乐川山地现场会议后，我队平巷普遍推广了木质脚踏打眼机，这种打眼机能减轻体力劳动，提高生产效率50％，很受工人欢迎。但由于打眼机冲击力大，扶钎者吃力，同时用人工掏取岩粉，辅助时间很多，岩矿尘飞扬，影响工人健康。在这种形势下，给技革工作提出了新的课题，要设计试制一种既能自动转钎，又能湿式凿岩的半机械化平巷打眼机。在队党委正确领导下，山地职工与修配车间大搞协作，采用三结 After the on-the-spot meeting in Lechuang mountainous area, the team lanes generally promoted wood-footed eye-opener.
