近几年间,在隧道与巷道建设中所用的传统方法已让位于许多完全自动的坑道掘进机。这一发展完全是现代技术发展的必然结果,它使矿工们免于从事危险的工作。象“打眼—装药—爆破—通风—装岩渣”这样的概念很快就将成为过去的事情。工作队将由机械工人及工程师组成,工作面就象工厂一样。每一个熟习隧道工人的这种极端艰苦、危险和很讨厌的工作的人确实欢迎这一成就。这几年来,由于矽肺病的危险,人们对这种职业的兴趣急剧下降,现在补充具备合格条件的矿工是困难的。工资迅速提高的趋势必然导致寻找新的方式,特别把重点放在:
In recent years, the traditional methods used in the construction of tunnels and tunnels have given way to many fully automated tunnel boring machines. This development is entirely the result of the development of modern technology, which exempts miners from doing dangerous jobs. Concepts such as “eye-opener-charge-blast-vent-mount rock residue” will soon be a thing of the past. The task force will be made up of mechanized workers and engineers, the face of which is like a factory. Everyone who is familiar with this extremely difficult, dangerous and annoying job of tunnel workers does welcome this achievement. In recent years there has been a sharp decline in interest in this occupation due to the danger of silicosis, and it is now difficult to replenish qualified miners. The rapidly rising wage inevitably leads to the search for new ways of paying particular attention to:
