山地工作操作的机械化，关系改善劳工操作条件，加快掘进速度和提前完成勘探计划，是一项极重要的问题，值得予以研究注意。勘探坑道的掘进，在组成工序上，和生产坑道的掘进是相似的。按照坑道类型的不同，掘进作业包括下列掘进过程：打眼爆破、通风、照明、排水、坑道支护、装岩、运输及提升等。不过勘探坑道掘进的 The mechanization of mountain work operations, the relationship between improving working conditions of workers, speeding up tunneling and completing exploration plans ahead of schedule are extremely important issues worthy of study. The excavation of the exploration tunnel is similar in composition to the tunneling of the production tunnel. According to the type of tunnel, driving operations include the following tunneling process: blasting, ventilation, lighting, drainage, tunnel support, rock loading, transportation and upgrading. However, exploration tunnel excavation
