一、掘进作业中的劳动保护措施(一)掘进作业的工序掘进作业是国防工程建筑中的重要作业项目之一.掘进作业必须保证:穿孔合理,爆破安全,不出或少出哑炮,排烟排险彻底,配框及时坚固,照明充足节约,及时通风换气,严格险情检查和彻底防尘等;并按正确的工序进行施工,借以提高工程质量,保证安全,加快施工速度,消灭对人体足以引起的一切伤害。掘进作业的第一步为坑道切口。坑道切口位置,以依军事需要而定,不能以确保施工安全为目的去任意选择,因而坑口部的土石质量是否容易塌方,对施工速度及安全有
I. Labor Protection Measures in Tunneling Operation (1) Process of Tunneling Driving operation is one of the important operation items in the construction of national defense engineering.Driving operation must ensure that: reasonable perforation, safe blasting, no or less dumb gun, smoke exhaust Completely riddled with timely and solid distribution of the frame, adequate lighting and adequate lighting, timely ventilation, rigorous inspection and complete dust and so on; and the correct process of construction, in order to improve the quality of the project, to ensure safety, speed up the construction of the body to eliminate enough Cause all the damage. The first step in driving a tunnel is to cut a tunnel. According to the military needs, the location of the incision can not be arbitrarily chosen for the purpose of ensuring construction safety. Therefore, whether the quality of the soil at the mouth of the pit is easily collapsed or not, the construction speed and safety
