"Boom, boom!"

An earth-shattering explosion. Bombing, and it seems to be a series of tight explosions. The sound of the explosion was deafening, and the rumbling sound and the shaking that made the earth tremble made people feel the yellow. The horror after the release of energy from colored chemicals.

The reason why everyone feels is either a sound, or a series of explosions. The sound of breaking is because if it starts. The chip of the detonator is set to impulse into a different way, deliberately making these detonation points seven thousandths of a second.

This design is due to the fact that the detonation speed of this mining explosive is about 5 kilometers. The blast was so powerful that the sound waves and vibrations could cause damage to people and surrounding buildings and geological structures.

And after such a little bit of time, it can not only make these detonation points almost explode together, but let the power play together, and the stones will be lifted away without causing harm.

Big Bang. After the explosion, within ten seconds, a puff of smoke and dust drifted over from there, and everyone immediately choked and coughed.

"Damn, uncle, why is this smoke floating here!"

The roots of the tree lying on the ground could not stand the smoke, so they quickly got up from the ground and ran towards the tent, preparing to hide in it to avoid choking on the smoke.

"Hey! Who is that running around, I don't know what to do. Is it forbidden to run around for three minutes after frying? ”

Noticing the explosion of his movements. The Breaking Technique Magician suddenly shouted loudly, startling the running tree roots.

"Get down quickly, don't run around!"

Yun Yi reprimanded loudly, and the frightened tree roots quickly fell to the ground again, burying their heads and not daring to continue to run.

Three minutes later.

"Roots, you dog. Day. The one that made you run around was said to explode at the beginning. Three minutes after frying before you dog can get up. Day. The ears are stuffed with donkey hair! ”

On one side, Miao Tianfu was standing in front of the root of the tree and reprimanding him. Let the root of the tree be trained to lower his head and not dare to say anything, and he was honestly trained for seven or eight minutes before he was let go.

After the blasting, two teams of seventy people began to get busy, with thick gloves in their hands and steel drills, and they poured on the stones that had been blown away by the explosives, and cleaned them out.

When the two groups struggled to clear the bottom of the rocks, a series of blasting points were revealed. The explosive exploded inwards about three meters deep, and there was an angle of about 20 degrees on it.

"Well, that's not bad, the rest of the bevel is hit with a wind drill, and after the bevel is blown out, it is exploding. Breaking it once is almost enough! ”

The technician with glasses nodded with satisfaction, and after letting the two groups of people continue to clean the stones here, he walked forward with Yun Yi and the others again, and continued to shoot along the opening that had just burst.

An hour later. Another sixty eyes were laid, and then everyone hid behind the mountain again, and after Yun Yi and Miao Lao Pao confirmed their safety, they got up again. Burst.

Wait for the safe time to pass. Everyone got up and went to clean up the stones, while Yun Yi and the others were in the explosion that everyone cleaned up just now. Broken holes left on the slopes.

This time, the hole is hit straight down, and this kind of blow will make the power go down hard, blowing up the remaining slopes. As a result, a lot of effort is saved when building roads.

Just after a while, Yunyi suddenly felt someone pat him on the shoulder.

"Brother Long, why did you get into the mountain?"

Yun Yi looked at Long Xiaotian in surprise and asked. casually handed over the wind drill to the side of the descendant.

"Hehe, this is not said on the official website of Qingyun Mountain, Qingyun Mountain is building roads, I want to come over and see if I can help!"

Long Xiaotian looked at Yun Yidao with a smile, and then he looked at the afterlife behind Yun Yi with some surprise, and asked a little strangely: "Yun Yi, you guys are bursting at this point. Broke it once, why did it leave such a big slope? Your technicians aren't qualified, right? ”

"Unqualified? It's hard to make it happen. Break, and it can explode at once. Break the slope or not? ”

Behind Long Xiaotian came the voice of the technician, he had just come back from the exploration over there, and when he heard someone say that he was not qualified, he looked at this man with some anger.

"Hehe, if you want to say this explosion. Break a little slope and don't stay, then I don't have the ability, but this time it exploded. I still have the ability to leave a slope of no more than an octave after the break! ”

Long Xiaotian turned to look at this skill artist and said with a slight smile.

"Okay, since you're so confident, let's go to the spot I explored earlier, where I've made a mark, and you can do a blast too. Break the mark of the point! ”

The skill artist was slightly stunned, listening to Long Xiaotian's confident words, but he was no longer as angry as he was just now, but looked at Long Xiaotian in slight surprise and walked towards him with him.

Yun Yi was curious and followed.

Long Xiaotian took the laptop of this skill technician, looked at it for a while, and then carefully observed the topography and geology of the valley, and finally looked at the rock composition with a chisel, calculated a little in his heart, and began to mark with a pencil.

The mark made by Long Xiaotian was a little different from the mark made by the technician just now, he followed the original mark, and moved the next mark sixty centimeters down one by one, and then wrote a few words on the marker that the technician had not moved the position of the mark.

At first, the technician was still confused and looked at Long Xiaotian's movements, but when he carefully approached the original mark, and saw the words 'hole depth of ninety centimeters' written on it, he was stunned at first, and then pulled Long Xiaotian's arm in ecstasy and said:

"Sir, no, buddy, no, master, you are really amazing, you can come up with such a subtle method, you can teach me how to blast better!"

Looking at the excited appearance of the technician, Yun Yi couldn't help but say strangely: "Brother Long, what is the difference between your mark and just now?" ”

Long Xiaotian smiled slightly, and after letting the excited technician stand firmly, he said with a smile:

"I'll let the cannon hole drop sixty centimeters every other time, and this is waiting for the next explosion. When it breaks, first let the upper blast hole explode one ten-thousandth of a second earlier, and then the lower blast hole is exploding.

So that the blast hole above is blown up. When the power of the charge is transmitted to the bottom at a speed of 5 kilometers per second, the explosives in the blast hole below will detonate, and the power of the blast hole on this side will be superimposed on the power of the blast hole above, making the base surface of the blast below more flat.

And I reduced the depth and charge of the upper blast hole by 30 centimeters, so that when the power of the upper blast hole is upward, it can just blow up the upper part of the mountain into an inclined shape; The sloped mountain is more stable than the steep mountain, I don't know this! ”

[It is forbidden to use this method as any engineering explosion. Broken, if the skills are not at home, there is no responsibility for any problems; If there is no problem, please pay the patent fee to Xiaolone, this is Xiaolone's original explosion. Breaking the technique, it is strictly forbidden to steal the teacher>-
