"The statement of the inverted fold in your implementation plan has been well confirmed in several drill holes that have been finalized so far!"

Qi Mingyuan opened the thick implementation plan again, and looked at the analysis chapter on inverted folds above, "Your vision and judgment are really very unique, I admire it very much!" ”

Wang Dasheng, Shen Jie and others also came over and watched carefully.

"How can you be so sure that there is a large inverted fold underneath the Minminerals?" Shen Jie wondered.

"I remember the last time we came over, the first drill was over, and you guys were disappointed."

Wang Dasheng remembered that when he came here a few days ago, it was also in this conference room, and the atmosphere was so solemn, "From the direction of your later work, you are still very firm in your judgment, and you still continue to arrange the boreholes according to the idea of inverting the folds."

For your persistence, I praise you! ”

Xu Xin never spoke, and he didn't want to explain too much.

However, Xu Hengqiang had something to say, "Our judgment is still biased, at least in terms of the third-layer steep mountain Tuo group, we still don't have any clue at present."

If you want to find out this, it all depends on the support of the leaders. ”

Luo Qiqi smiled and nodded, but those small eyes were always staring at Xu Xin.

He didn't know what he wanted to see from Xu Xin, but he was still curious.

Seeing that the time was not early, Xu Hengqiang stood up and said with a smile: "It's lunch time, our technician picked some wild vegetables when he was working in the field yesterday, which is very suitable for making spicy hot pot, you can enjoy your face and have lunch?" ”

"yes, I like the food in the mines!" Luo Qiqi is really looking forward to it.

"Let's go, eat more at noon, and come back with some food from Lao Xu." Wang Dasheng joked in a loud voice, "I feel like I missed a big project and was taken advantage of by Lao Xu!" ”

The so-called wild vegetable is actually the leaves of nettle grass that can be found everywhere, and after scalding it with boiling water, it becomes a delicious wild vegetable by rubbing off the spikes on it with gloves.

The young leaves of nettle grass are thrown into the hot spicy pot, scooped up, put in the mouth and chewed, the spicy flavor and the fragrance of nettle grass juice are mixed together, which can strongly stimulate the taste buds.

A large basket of nettle grass was wiped out in one meal.

On the contrary, the fresh mutton that was bought from the city to entertain the leaders did not move chopsticks much.

After lunch and an hour's rest, everyone headed to the rig to check the core.

Qi Mingyuan and the others all had the same idea, that is, they wanted to take a look at the ore layer with their own eyes and confirm it.

Of course, they knew that it was impossible for Xu Hengqiang and the others to fake, because the technicians of the Fu Phosphorus Group were stationed here, and their drilling technicians and workers were the first to see the core taken from the ground.

After looking at the cores, it was determined that the rock formations were not much different from the borehole histograms shown at the morning meeting.

The matter of the mine in the Minmetals section must be a certainty!

When Luo Qiqi and the others left, Xu Hengqiang, Jiang Yehu, Xu Xin and others did not send them, but continued to stay in the mine.

"Now that we agree with our idea, we must now determine the location of this deep hole as soon as possible."

The sun was bright, Xu Hengqiang did not wear a hat, squinted his eyes and looked around at the large gravel mines, "Before the results of the deep holes come out, other boreholes will not be arranged." ”

"That's true, only when the results of the deep hole come out to determine whether the third layer of the steep mountain Tuo Formation exists and whether the ore is seen, can the drilling be arranged."

Jiang Yehu said as he spread a huge engineering layout plan on the ground, pointed to one of the holes and said, "Lao Xu, why don't we set a deep hole location next to a few mine holes." ”

"Yes."

"How about this hole ZK5305?"

Jiang Yehu pointed to a point on the map, "ZK5306 and ZK5307 have good ore encounters, and the ore layers look stable and continuous, and there is a great chance of ore encounters in this hole next to them."

I think that when we drill this deep hole, we first make sure that the third layer of phosphate block is intersected, and then we look for deeper layers underneath. ”

"You're right, so let's do it." Xu Hengqiang glanced at the project layout and settled down.

Jiang Yehu took out the tablet computer in his backpack and quickly checked the coordinate location of the drilling ZK5305 on the computer.

Put away the computer, take out the GPS, and about to walk to the drilling position, and beckoned a drilling rig captain who has been following him, "You come with me, determine the drilling location now, and move the large drilling rig into the field today." ”

Xu Hengqiang suddenly stopped Jiang Yehu, "You take the GPS to Xu Xin and let him locate it." ”

Jiang Yehu was stunned for a moment, turned around and showed a simple smile to Xu Xin, and handed over the portable GPS in his hand.

"I don't know how to do it."

Xu Xin caught the instrument and looked at the few buttons on it like a calculator, looking confused.

When he came to survey with his father before, Xu Hengqiang taught him to use this instrument.

But he turned around and forgot, now Xu Hengqiang asked him to use GPS positioning to drill holes, which was intended to test his practical ability.

For these old geologists, this job is really simple.

But for Xu Xin, that was really a big problem.

He scurried around the mine, staring at the ever-changing string of numbers on the portable GPS screen, dazed.

What's that?

In Heijin Province in October, the mountain breeze is cool, but under the sun, I still feel a burning sting pain on my skin.

Xu Hengqiang, Jiang Yehu and others seemed to be accustomed to this kind of field work without hats, but Xu Xin couldn't stand it, standing in place, looking around, very helpless.

Xu Hengqiang really wanted to test Xu Xin's hands-on ability, and followed behind with a black face, his face getting worse and worse.

Jiang Yehu always smiled, very happy, seeing Xu Xin's embarrassment, he hurriedly prompted: "You just need to compare the borehole coordinates I just gave you with the coordinates on the GPS, as long as the error range is within the allowable range of the specification, there will be no problem." ”

Xu Xin knew this truth, but he was very clumsy in operation.

In the end, after Jiang Yehu's professor, he finally found the right location for the drilling.

In the following days, according to Xu Hengqiang's arrangement, Xu Xin was incorporated into the drilling cataloging team.

Because ZK5305 has a significant impact, basically every time the drilling rig drills about 50 meters, it has to carry out a phased cataloging work.

And in order to get results as soon as possible, the drillers basically work in three shifts, 24 hours a day.

Sometimes, in the middle of the night, when the core is extracted and a suspected ore layer is found, the drill rig captain directly calls the technician and goes over in the middle of the night to make a geological catalog.

Six days later, the rig penetrated the third layer of the Steep Mountain Tuo Formation.

The borehole depth was fixed at 710 meters.

After using the instrument, it is found that the grade of the phosphate block rock in the third layer of the steep mountain tuo formation is very low, and the thickness has become very thin, from the original two layers of phosphate block rock is basically 20 meters thick, to one or two meters thick, and the original interbedded siliceous dolomite has become thicker.

After analysis, Xu Hengqiang gave a guess that the ore layer gradually changed to siliceous dolomite.

In other words, the Tertiary Steep Mountain Tuo Formation is only localized mineralization and is far from reaching the recoverable grade.
