A tunnel boring machine is a machine that can dig tunnels that are mostly used for trains.
The machine has 6 main parts the
segment, the thrust ram, the conveyor belt, the gripper ram,
the scraper, and the cutting teeth which are all used to make the
machine work. An interesting fact I learned is that the worlds longest tunnel is in
Japan and that it is 54 kilometers long. There is also a smaller
boring machine which is used to drill into small rocks to retrieve
diamonds, rubys, and other valuble minerals. I would like to see
this machine make mining safer for the workers and also to create
longer distance tunnels for trains. My info was from How Things Work
I enjoyed your presentation in class. Could you use 1 of the pictures from your presentation here so others could see just how big this machine is?
ReplyDeleteDo you know what the maximum distance is?
