Experts are also at a loss to get the temperature measurement data, standing on the ground and analyzing what is happening at a depth of more than 1,000 meters, which is really not easy, and there is too little data to refer to. Pen, fun, pavilion www. biquge。 info

In the end, the expert came up with a plan.

"I'm going to do a seismic survey."

"Seismic surveys?" A completely foreign word.

"To put it simply, it is to make a few deep holes in the ground, put a detonator in the hole, and then detonate it, the explosion wave formed will continue to propagate along the earth's crust, like sound waves, this vibration wave will also produce echoes, we use special instruments to test this kind of echo, we can calculate the general structure of the underground through data analysis, and calculate what changes have occurred in the underground."

“...... Is there any harm in this kind of seismic survey? "The first thing that came to the director's mind was the scene of the coal mine blowing up the mountain, the kind of ground shaking the mountain, and a mountain was blown up in an instant, playing this in the scenic spot......

"Even in our karst geological structure, seismic survey is not a big problem, at most we can control the depth of the borehole, it should not have much impact."

"Oh......" After listening to the expert's explanation, the director relaxed slightly, "This ...... I don't know how much this survey will cost......"

"It's not cheap, you need to find a special exploration team, rent a drilling rig, drill deep holes, maybe tens to hundreds of meters, and then you need a seismic detector. It depends on the situation to play a few points and put a few shots, and the data processing of seismic waves also requires costs, which are basically charged per frame, and I estimate that this cost is at least one million. ”

Hiss~~~

The director gasped, this cost ...... That's enough for 10,000 people......

"This fee is a bit high, is there any other way?"

"We are like doctors, who have come to see a doctor in the hot springs, but the doctor must have examination data to dare to confirm the diagnosis, there is nothing, just a little water sample, temperature data, I can't see too many things."

"If you think the cost is high, there is another way, you can try, you can see if you can find the satellite remote sensing department, ask them for the recent period, the remote sensing data in this area, maybe it can also be a little valuable, but enough, after all, remote sensing is large-scale photos, it is difficult to see the details."

The director thought about it for a long time, and felt that since the experts said that finding remote sensing data is also a way, this estimate will not cost too much.

In order to spend less money, the director dug the door and stole the hole to find the relationship, all kinds of friends to friends, and the relationship to the relationship, and finally found a line that could provide remote sensing data.

After discussing it with others, it cost a few thousand yuan, and the director pressed the latest remote sensing data, and he quickly took the data to the experts.

"What time is your remote sensing data here?"

"A week ago! This is the latest and I can't get the updated data. ”

"Is there any comparison data?"

"Compare the data? What is it for? ”

"It's the remote sensing data in the normal time period of your hot springs, there is no comparison data, how do I know where the changes have been?"

"Oh~~~ Yes, yes, it's relatively old, it's a year ago." These data didn't cost money, they were directly given away for free when people saw what he needed.

"Oh...... I'll take a look at ...... first," the expert said, picking up the remote sensing data and looking at it seriously.

After watching it for most of the day, the expert raised his head and asked the director, "Did you do anything before and after the hypothermia in the hot springs?" ”

"What to do?" This question is a confusing question for the director.

"Before and after the hot spring hypothermia, have you ever moved the soil in your scenic spot, engaged in construction projects, and have there been major geological and climatic events?"

"Climatic and geological events should be without ...... Earth...... We were planning to build a hotel building a while ago, and we dug the foundation, does this count? ”

"Digging the foundation...... There wasn't a collapse or anything like that, did it? ”

"I haven't heard of it...... I don't know the specifics, or I'll call the person in charge and ask. ”

"Good!"

Not at all, Section Chief Xiao was called.

"Shaw! Experts asked us about the original digging of the foundation, did there happen to collapse or anything like that? ”

"Collapse? No, everything works fine when digging the foundation...... There may be one that is not quite normal. ”

"What's the matter?" The director's eyes lit up immediately.

"When I was digging the foundation, I dug up a section of water pipe, and then I checked it again, and there was no water pipe at that location at all, and then no other pipelines were found, so the matter was over."

"That's it......" the director was full of joy and came to naught.

"This has nothing to do with us, is there anything else going on?"

"Then there won't be!"

"That's weird......" the expert muttered to himself.

"What's wrong? Can I help you? "Listening to the expert's tone, it seems that there is really something, could it be that the hot spring hypothermia has eyebrows?

"Judging from this comparative data, the geological structure of your subsurface changed dramatically before your hot springs went hypothermic."

"Geological structure changes?" The director couldn't help but be surprised, doesn't this mean that the hot springs are completely out of play?

"Judging from the data, there should have been a huge underground space underneath you, but now it seems that in the recent past, the material composition of this space has changed, maybe there has been an underground water permeability accident, or the rock layer has collapsed, anyway, there has been a change in the position of the underground space."

"Underground space? Does it have anything to do with our hot springs? ”

"To be precise, the waterway of your hot spring passes through the vicinity of this underground space, and if this underground space changes, it is very likely that it will affect the hot spring. Since your hot spring is hypothermic and this underground space happens to change abnormally during that time, there may be some causal relationship between the two. ”

"That'...... You see, is there a way to restore the hot springs again? ”

"It's hard to say, let's first determine the specific cause of the hot spring hypothermia, if there is a problem with the geothermal heat of the lava rock, then it is useless for you to think of any tricks, and people will not be able to win the sky at any time."

"If it is not a problem with the geothermal heat of the lava rock, but a problem in other aspects, maybe there is a possibility of saving, since the flow of the hot springs is no problem, if the geothermal heat is no problem, then it is a big deal that you dig a deep water well and directly lead the hot springs underground, so that the hot springs in your scenic area can also be restored."

"It's just that this method of drilling deep wells directly may affect the mineral content of the hot springs, and in that case, the quality of the hot springs may deteriorate."
