Chapter 70

A hundred miles from the valley where the camp is located.

Near a slightly hidden riprap.

Dozens of impact crushers, Hammer Crushers, compound crushers and a series of mining facilities such as drilling machines, ball mills, vibrating screens, sand washing machines and belt conveyors are neatly arranged in front of a semi raised entrance.

The width of this entrance is about seven or eight meters. It is inserted into the ground at an angle of 45 degrees. From the entrance to the edge of the rubble pile, a flat and wide avenue has been artificially cleared.

The avenue is nearly ten meters wide and can accommodate large vehicles.

On the side of those instruments, hundreds of Chinese wearing hard hats were standing scattered at this time.

These people are from the exploration department and Mining Department of a large state-owned mining enterprise in East China. They are all industry elites who have worked for more than 20 years.

According to the original plan.

This group of exploration and development personnel will depart from modu airport and go to a small country in Africa for ore exploration and mining.

These people signed a two-year overseas work agreement before going abroad, and their families were also prepared for long-term separation.

Now the world of Mozambique is in the development stage, so these talents are naturally intercepted.

After a series of operations, they were secretly dispatched to Da Mo world.

Like Wu fan and others.

This group of personnel can have a simple contact with their families at regular intervals - through special equipment.

With the participation of such a group of mining elites, the exploration speed of Lingshi vein immediately increased by a large margin.

In addition, Wei Siming once applied anti collapse and leakage means to the interior of the ore body, and the characteristics of Lingshi do not need ore testing and analysis.

So after a few days of uninterrupted work.

The mining project has finally gone through a series of links, such as determining beneficiation method, selecting site foundation treatment, installation and commissioning, and reached the most critical node:

Mine!

The general person in charge of the mining task is Lei Wenjun, deputy director of mordu Geological Research Institute, and the person in charge of the mining project is a section chief surnamed Fei from Qingyuan national mining industry section.

"Deputy director Lei, the equipment has been debugged."

Chief Fei, wearing a helmet, unfolded a profile of the ore vein and said to Lei Wenjun:

"The main tunnel of Lingshi vein is about 200 meters underground, and there are several turns in the middle.

Therefore, we adopt the traditional deep underground process, take the vibration ore drawing technology as the core support, and lay the electric rake roadway in the ore vein.

However, because the vein contains a large number of gently inclined medium thick ore bodies, we can only do semi mechanized mining.

Now the position of the hole has been set. According to your requirements, we will start digging from the 31.8 degree inclination on the left.

According to our survey, there should be a large number of 'parent plants' in this area. "

According to Wei Fan's previous introduction.

After forming, the spirit stone will be wrapped with a very thick rock surface.

The complete body on the surface of this rock together with Lingshi is the parent plant.

Generally speaking.

A parent plant with a diameter of about one foot can mine one to three standard units of spirit stones - that is, between one and three.

The area demarcated by chief Fei is a place where a large number of seed and mother plants are suspected to gather.

Lei Wenjun first rechecked the excavation inclination with a pen, and then said:

"The inclination is between 31.6 and 31.9, no problem.

The density of the single hydraulic prop should be strengthened a bit. In case of liquid leakage due to the increase of roof pressure, the effect will be bad. "

Chief Fei nodded: "I'll check it again."

Ten minutes later, chief Fei returned:

"Deputy director Lei, all equipment and indexes have been debugged. Please ask the headquarters for instructions!"

Lei Wenjun's dark face suddenly looked very dignified when he heard the speech.

He held the communicator tightly in his hand and took a deep breath to ensure his voice was stable:

"Headquarters, headquarters.

This is the stop point in front of the "mountain craftsman" project.

All our instruments have been debugged, 132 people have been verified and are in place. We request the headquarters to authorize mining! "

A few moments later, a large number of replies came from the messenger:

"Grant authorization, core console code xw45

Mine, deputy director Lei! "

Hang up.

Lei Wenjun looks at chief Fei:

"Mining!"

The voice fell.

Chief Fei raised his right hand fiercely, his palm flat, his four fingers close together, and the big sow was perpendicular to her four fingers - a common preparatory gesture in the mining industry.

At the same time, he paged all team leaders:

"All departments have, start operation!"

Boom——

The hydraulic drilling machine roared and began to dig according to the accurately calculated inclination by means of three tail multiple connection.

At the same time, all departments are also doing collaborative reporting:

"The advance support density of the two lanes is normal, and there is no need to return the columns one by one!"

"Check that the drill rod is not bent and the rock drill is not blocked!"

"The safety of the working face is in good condition. It is about to touch the soft rock stratum. Apply for increasing the times of powder discharge!"

After a while, the captain of the drilling team heard:

"The resonance displacement of the rock wall is very small, and the water content in the sand in the drilling area is very low.

Whether to send personnel to go down to the mine to excavate the parent plant? Please indicate! "

Lei Wenjun clenched his hands and solemnly gave the last instruction:

"Please be careful when sending personnel to the mine!"

In six minutes.

Three experienced mining elites were fully equipped and entered the mine together with an officer from the Wei government.

Watching the figure of the four disappear at the mouth of the mine.

Lei Wenjun, section chief Fei and the leaders of the camp hundreds of miles away are all waiting for the final result with a dignified look.

Twenty two minutes later.

Four people rose out of the mine mouth.

Different from entering the pit.

At the time of mining, each of them held a stone ball with a diameter of about 30 cm tightly in front of their chest.

The moment I saw the stone ball.

Lei Wenjun's heart was suddenly whipped.

He hurried to the pit entrance and asked several miners:

"Masters, is this..."

One of the oldest masters wiped the ash on his face and handed the stone ball to Lei Wenjun:

"Yes, after the confirmation of the Wei family brother, this is the parent plant!"

Lei Wenjun took the stone ball and slowly breathed out a big breath.

With one hand protecting the stone ball and pressing it on his chest, and the other hand lending strength to the mining work, he asked:

"Master, what are the reserves of spirit stones in the area we selected?"

The miner then jumped out of the mine with Lei Wenjun's force and patted the dust on his thigh with his hand.

Then he replied:

"Vice President Lei, the coal mines in our selected area... Well, I'm sorry to say I'm used to it. There are a lot of spirit stones.

The naked eye can see a large number of molded bodies of parent plants, and the line of sight and traffic width are very suitable.

More importantly.

The inclination selected by the console is very accurate. It just passes through between two soft rock layers without damaging any soil wall of the parent plant. "

"That's great. The inclination is indeed the interval we calculated!"

Lei Wenjun's face could not help showing a sense of pride. He calculated the inclination angle with his own hands.

Then he chose one of the four plants at random and took chief Fei aside.

Pop.

He put the seed and mother plant on the table, took out a knife provided by the Wei family from his pocket and said to chief Fei:

"Director Fei, the headquarters has explained before.

If there is ore, we should randomly select a parent plant and open it for inspection.

Who do you think will cut this knife? "

Chief Fei didn't answer directly, but stretched out his hand and pointed to his face: "what's my name?"

Lei Wenjun looked blankly: "chief Fei."

"I mean the full name."

"Fajo."

"Then you ask? I won a prize for beer. I haven't won it yet. Dare you believe it?"

Lei Wenjun: "

Then fajo waved her hand, and her eyebrows drooped in an instant:

"My hero League plays cards and mends knives, 1 gold coin a day, playing DNF has never strengthened more than 12 weapons, and the yin-yang master has never seen two Buddhas.

Last year, the Ministry of industry carried out a national scientific and dry sampling inspection, and I was missed among 120000 people. As a result, I didn't win the year-end bonus. Just bought a house, there was a suicide in debt in the community, and the house price fell by one-third on the same day. Just bought a car, the price of the new energy policy was reduced by 10% the next day. The most outrageous thing is that the author of several books that he even read is a month beast

Vice President Lei, I heard that one or three spirit stones come from the mother plant? Do you believe I'll give you a change? "

Lei Wenjun listened to the cold sweat coming down: "... I'd better come."

Then he eased his mind, picked up the knife provided by the Wei family and carefully cut the parent plant.

The surface layer of the parent plant is composed of rocks, but it is extremely sticky and soft when cutting in, and the hardness of the stones can not be felt at all.

A moment later, the rock split in two.

I saw three spirit stones lying quietly in the center, emitting a green light.

Lei Wenjun carefully picked up a spirit stone and held it in the palm of his hand like a baby.

In fact, in a sense, babies and spirit stones are somewhat similar.

Babies represent the extension of life.

The spirit stone represents the future of a great nation

Lei Wenjun took a deep breath, turned his head and said loudly through the walkie talkie:

"All departments... Work hard!"
