May 8, 1982 is a day worthy of being remembered by all the cadres and workers of the underground bauxite mine in Heyuan City.

On the first day, Wilson, deputy director of sales of MD White Mining Equipment Manufacturing Plant, led a team to follow the train to bring all the automatic drilling and blasting system equipment for trial in a single sub-mine transported from MD thousands of miles away, and also spent $300,000 to temporarily hire 30 well-trained workers with rich experience in underground mining from the Morunsea Copper Mine in Arizona.

On Zhong Bai's side, the official team was led by Ma Yingsheng, deputy director of the Planning Department of the Ministry of Industry, Lv Xudong, deputy director of the Tianhe Provincial Department of Industry, Fu Chongshan, director of the Technology Division, Miao Lirong, director of the Equipment Division, and He Xianglei, deputy director.

In addition, he also has foreign aid - Yu Dongfeng is of course indispensable, this time he can't run away from the whole process, in addition, Zhong Bai also directly invited his teacher Professor Yuan Jianguo over the phone, plus Brown and Ricky, two French professional mining engineers who have resigned from the Swiss Patent Office, this set of practical teams is also a good match.

As for the 3,000 DWX31-180/100X hydraulic struts, they have been in place three days in advance, waiting for the on-site installation to start.

The lineup of the two sides is not strong, and even ZF of Heyuan City attaches great importance to it, and sent Deputy Mayor Ni Jie to greet and accompany him throughout the process, as well as witness the process of participating in the trial of the entire dual program.

Of course, for local ZF, it doesn't matter what plan to choose, the important thing is to quickly decide which set to use, and let the mine quickly increase production, contribute more to local tax revenue and employment, and maintain personnel stability, which is enough.

In order to ensure the absolute fairness of this competition, which side of the selected No. 2 sub-mine and No. 3 sub-mine chooses which one must wait for the on-site lottery to decide, rather than drawing in advance, to avoid the suspicion of black box operation.

For the people of Heyuan City and the cadres and workers of the mine, it was the first time to see so many blonde and blue-eyed MD people appear alive in front of them, so on the first day of preparation, there was always a large group of people following behind to look at the diorama, and finally Wilson was on fire, and directly complained to Ma Yingsheng, saying that you are interfering with the environment of the competition, which is unfair!

Ma Yingsheng had to give Deputy Mayor Ni Jie a reaction, and in the end, the local ZF directly asked the Ministry of Armed Forces to send militia to block the road from the outside of the bauxite mine, so Wilson did not continue to force.

Seeing Zhong Bai and his party again after half a month, Wilson seemed to have regained his confidence this time, and when he met with Ma Yingsheng and them, he kept praising their automatic drilling and blasting system equipment on the spot, while secretly looking at Zhong Bai's preparations.

But it's a pity that Zhong Bai's secrecy work is quite good, 200 DWX31-180/100X hydraulic pillars to be used this time are all locked on the car, and a group of skilled workers selected are usually not outside, so Wilson didn't see any way.

Wilson saw that his investigation was unfavorable, and he also became suspicious, and even ordered their people not to go to the canteen to eat, and specially hired two Western chefs from Heyuan City to cook, and the cooked meals were also directly delivered to the workers and the rooms where they lived.

"Bradley, you've been observing for a day today, have you noticed any special equipment they're transporting to the mine?" After eating a chicken breast sandwich for dinner, Wilson closed the curtain and asked Bradley, the technical engineer next to him.

"No, no special equipment." Bradley's tone was firm: "From the beginning to the end, they only carried a large truckload of DWX hydraulic struts, and the rest should be equipment from atomic mines." ”

"Hehe, this young man is really arrogant! The Chinese people are not aware of the power of the automatic drilling and blasting system at all! Wilson is now full of confidence: "The scale of this mine is really not large, you have also read the drawings of the sub-mine, how is the mining plan formulated?" ”

"It's been preliminarily formulated, Deputy Director." Bradley is much more eloquent when it comes to professional issues: "The diameter of the two sub-mines is 12M, the average height of the inside of the mine is 4.5M, and according to their original mining method, the daily production of bauxite should be about 450 tons. ”

Wilson raised his eyebrows: "What about after getting on our automatic drilling and blasting system?" ”

"ACCORDING TO THE DIAMETER OF 18M AND THE AVERAGE HEIGHT OF 6M, IT IS CONSERVATIVELY ESTIMATED THAT WE CAN INCREASE THE DAILY OUTPUT OF BAUXITE IN THE EXPERIMENTAL SINGLE-BLOCK SUB-MINE TO ABOUT 700 TONS." Bradley was quick to give the data.

"450 tons to 700 tons, basically an increase of 50% of the production capacity." Wilson touched his chin and smiled: "That guy, he said that his plan can be increased by 40%, and I will see what he can make up for the middle 10%!" Tonight, let the workers eat and sleep well, and get up early tomorrow morning, you will take the workers to debug the equipment on site to ensure that there are no problems, and then go into the mine to install! ”

"Yes, Mr. Deputy Director." Bradley nodded solemnly.

"What is the total mining time tomorrow?"

"When working on 10 standards, you can take a break in the middle of the work, and the machine stops running and the timer stops at the same time." Bradley has read the rules back and forth several times, after all, they were made by both sides, and no one should try to exploit loopholes in them: "But given that our plan is more automated, the machines should not be stopped and the workers should not rest too long, otherwise the mining efficiency will be lost." ”

"Is there a way not to lose mining efficiency?" Hearing Bradley say this, Wilson immediately frowned and asked.

"Yes, there is, but ......"

"Don't babble, just say it! What a way! Wilson looked impatient.

"The way to do this is to work straight for 10 hours without breaks." Bradley licked his lips and said, "It's completely feasible for the machine to go without rest, and we've also been stress tested in this area, and the key is the 30 workers we hired temporarily from the Morunsea Copper Mine in Arizona this time......"

"What happened to the temporary workers? Anyway, it's just a day's work, ten hours of continuous work is a bit more intense, but aren't we going all this way here just to dig up as much ore as possible tomorrow? Although Wilson is not very good at technology, he has a good set of people: "As long as you win tomorrow, everything is easy to say!" Their full hire fee this time is $10,000 per person, and you can tell them later, if everyone can work for 10 hours without a break, each person will be given another $1,000 bonus! ”
