What Are the Shakes in Tunneling： Causes and Effects

Now, let me tell ya about them shakes in tunneling. You know, when they dig big holes in the ground, like for roads or trains, sometimes strange things start happenin’. The whole ground might start shakin’. Why’s that? Well, it’s ’cause of all them machines diggin’ and blastin’. These big machines, they don’t go in soft and easy, they gotta use force, and that force makes the ground tremble.

Ya see, when they start tunneling, they might hit rock, dirt, or even some soft stuff like clay. But here’s the thing—rocks ain’t always friendly, they can fight back. When the machines break through, the ground starts shakin’, and them shakes, they can cause real trouble.

Why Do Shakes Happen in Tunneling?

The big reason why them shakes happen is the way the machines work. They use something called “blasting” to break the rock. Now, when that blast goes off, it sends waves all through the ground, makin’ everything shake. It’s kinda like throwin’ a big ol’ rock into a pond, and you see the ripples spreadin’ out. But here, them ripples are tremors, and they can mess with the tunnel if folks ain’t careful.

Now, these shakes, they ain’t just about what you feel on the ground. Nope, they can cause cracks in the walls of the tunnel, or even worse, cause a collapse if the tunnel ain’t built strong enough. That’s why them folks gotta be mighty careful when they’re blastin’ away.

How to Stop the Shakes?

• First thing they do is plan real good. They gotta look at the ground and see if it’s weak or strong.
• Then, they might use smaller blasts, so the shakes ain’t as bad.
• They can also reinforce the tunnel with strong materials like steel or concrete to hold it up, just in case the ground gets shaky.

Sometimes, the shakes don’t just come from the blasting. There’s other things too, like if the ground has water. Water can seep in and make the ground soft, so when them machines hit it, the whole thing shakes even more. Now that’s a whole mess of problems, ‘cause water and dirt mixin’ can make the tunnel walls collapse if they ain’t careful.

Different Types of Shakes

Not all shakes are the same, ya know. There’s little ones, where you barely notice ‘em, like when a cat’s walkin’ soft. But then there’s the big ones, them tremors that make the whole ground rumble like a storm’s rollin’ in. Sometimes them big shakes come from deep in the earth, like after an earthquake or if the tunnel’s near some old mine. Mines, they leave weak spots in the ground, and when you dig close by, everything might start shakin’ real bad.

Blasting and Mining Shakes

Blasting is one of them things that makes the biggest shakes. Ya see, they use explosives to blow up the rocks so they can keep diggin’ the tunnel. When them explosives go off, the ground shakes from the force of the explosion. But sometimes, if they ain’t careful, them shakes can reach far, even to places outside the tunnel.

In them mines, folks been dealin’ with shakes for a long time. They call ‘em “mining tremors.” When they dig deep down and the rocks can’t hold up no more, the ground shakes. It’s a dangerous thing, ‘cause it can damage not just the tunnel but also buildings up on the surface. So they gotta keep track of where the shakes might happen and make sure the tunnel’s safe.

How Do Shakes Affect the Workers?

Now, them shakes ain’t just tough on the tunnel. They’re tough on the folks workin’ down there too. You ever try standin’ on shaky ground? It ain’t easy. Sometimes them shakes are so bad, it makes folks feel dizzy, tired, and even scared. When the ground’s movin’, they gotta work fast but safe, makin’ sure nothin’ falls on their heads.

And if there’s gas down there, like carbon monoxide, them shakes can cause leaks, which makes it even more dangerous. Gas leaks are real bad ‘cause you can’t see or smell it, but it can knock a person out if they breathe too much of it.

Preventing Shakes in Tunneling

• They use strong materials to build the tunnel walls, like thick concrete, so the shakes don’t break ‘em.
• They measure the ground to see how bad the shakes might get and plan how to dig without makin’ things worse.
• Sometimes, they even stop the machines if the ground’s too shaky and wait for it to settle down before diggin’ again.

So, next time you hear about tunnels shakin’, you’ll know it ain’t just ‘cause the ground’s mad or somethin’. It’s all them machines and blasts diggin’ away at the earth. And the folks diggin’ the tunnels, they gotta be real careful, or else them shakes could cause a heap of trouble.
