一、绪言在党和人民政府的正确领导下,中国人民的水利事业已经蓬勃地发展起来,年轻的水工隧洞工程,也在日新月异的前进和发展着。今天祖国人民在十五年内赶上英国的伟大号召下,鼓起了革命干劲,实现着全民的生产大跃进,新的技术革新浪潮,将勇现出更高的浪头。这样不能不回顾一下在以往的设计工作中,所存在的一些墨守陈规的工作方法和计算公式,重新加以斟酌和考虑了。在隧洞施工中,由于工作面的狭窄,工种工序又很复杂,因此使得整个掘进工作的机械化,将受到很大的限制,但是在掘进工作中的钻眼,爆破,运碴的三种主要作业中,若能正确而严密地组织施工,充分地利用和恰当地选择机械设备,这将对于隧洞工程的建筑期限和建筑成本有着决定性的意义。在捷克斯洛伐克矿山,通过坚硬的石英化了的有花岗岩脉的板岩中,开挖断面为10.5M~2的横洞
I. INTRODUCTION Under the correct leadership of the party and the people’s government, the Chinese people’s water conservancy has been vigorously developed. The young hydraulic tunnel project is also progressing with each passing day. With the great call of the motherland to catch up with Britain in 15 years, the motherland of the motherland has mustered revolutionary vitality and has achieved a wave of technological innovation. In this way, we can not but review some of the conventional methods of work and formulas that have existed in the past in the design work and have re-considered and considered them. In the process of tunnel construction, due to the narrow working face and the complicated working procedure, the mechanization of the whole tunneling work will be greatly restricted. However, the three main operations of drilling, blasting and transporting ballast in the excavation work It is of decisive significance for the construction period and the construction cost of the tunnel project if the construction can be organized correctly and strictly and the mechanical equipment can be fully utilized and properly selected. In the Czechoslovak mine, through a hard quartzite granite veined slate, excavation of a cross section of 10.5M ~ 2 horizontal hole
