一、提要早在1957年人们就曾试图把隧道掘进机应用于井下采矿生产。虽然隧道掘进机在排挤传统的凿岩一爆破一装矿的巷道掘进作业尚未构成威胁,然而在某些条件下最新的现代隧道掘进机在掘进速度方面却比传统的掘进方法遥遥领先。本文介绍了评价适合于用机器凿岩的条件,讨论使用隧道掘进机有关的各种费用,评述使用隧道掘进机比用传统方法掘进的优越性。
First, as early as 1957 people have tried to tunnel boring machine used in underground mining production. Although tunnel boring machines have not posed a threat to exclusion of conventional rock-blast-blasting tunneling, the newest modern tunnel boring machines, under certain conditions, are far ahead of conventional tunneling methods in terms of tunneling speed. This article describes the evaluation of conditions suitable for drilling with machines, discusses the various costs associated with the use of tunnel boring machines, and reviews the advantages of using tunnel boring machines over conventional methods of tunneling.
