The Mongolian Provincial Police are indeed very powerful. The Ulan City Bureau provided five large excavators to the Xinghe County Bureau. In addition to the three excavators provided by the Xinghe County Bureau, they began to dig from several directions at the place where the landslide occurred.
.
Although it has been decades, after all, the place where the collapse occurred at that time was about ten meters underground, so the only way to do it was to dig out the entrance of the mine first.
However, because there are other mines nearby, we can only operate during the day and must stop after dark.
At this time, Fu Cheng and Tang Shuaishuai led their team members to look for inaccessible hills and hills, and places where trees had been recently planted.
In the end, after digging for a long time, nothing was found, but there was no focus at this time, so I could only use this method as a magic weapon.
Du Dayong went to bed early tonight because the excavators here all get up early to work.
Another main reason is that Du Dayong believes that the root cause will only appear on these two lines. De City and Wucheng County Bureau have passed the screen once, and the Provincial Bureau of Criminal Justice Brigade has passed the screen again, and almost all have been screened.
After thoroughly exploring the surrounding circumstances of this case, only these two lines of hope still exist.
Moreover, Du Dayong also prepared for the worst, and his team could not solve this case either.
Du Dayong felt that as long as his team did their best, even if the case was not solved as scheduled, it was still an exercise. At worst, he would lose some of his halo effect, or even delay the evaluation of professional titles by a few years. These would be of great benefit to him.
It doesn't matter, as long as the members of his team can still have the confidence to continue to do their best in future cases, Du Dayong thinks that it doesn't matter if he fails to solve the case as scheduled.
From the moment he took over this case, Du Dayong had no idea that this case would turn out like this for his team.
But now that this is the case, I can only bite the bullet and continue to follow the established ideas.
Early the next morning, at 5:30, Du Dayong washed up, ate something, and rushed to the excavation site.
By the time Du Dayong and the others arrived, the excavator had already started digging.
At this time, Du Da had no choice but to watch.
By noon, the mine entrance was finally found.
At this time, the excavation speed could only be reduced, and at the same time, only two medium-sized excavators began to dig slowly.
The Xinghe County Bureau also hired engineers who were familiar with mine work to stay at the site.
When the mine entrance was dug to a depth of five meters, the two engineers showed puzzled expressions.
Du Dayong knew at a glance that someone must have discovered something here.
"You two, is there something wrong?"
"Why are there no support boards? Even if there were no steel top supports at that time, wooden sticks and wooden boards would be used to support the top."
"And this can't be a private coal kiln. Even if it is abandoned, there won't be a single wooden stick in the top arc, and so far I haven't seen a single piece of dead wood."
"You two are saying that as long as there is a vibration, this place will collapse?"
"You don't understand. This is almost a fault layer. Otherwise, why would we abandon this place? As long as there is enough vibration, the entire area here will collapse, and then this place will be blocked. Judging from the current excavation situation
Look, this place was collapsed by the earthquake, and there are too many large pieces of ore."
"The coal quality here is still good, with coal ranging from 4,200 to 4,500 cal. We can explore it here and we should be able to open a new well."
When Du Dayong heard that these two people were actually studying this, he quickly interrupted.
"You two, can we study how deep this mine is normally?"
"Police officer, how do we know how deep the mine is? We have newly opened an old mine here. Generally, the previous excavation depth was about 16 to 20 meters. At that time, the main producing area of coal mining was not here, so we only
It can be this deep, and the coal here is interlayered. For example, this coal belt is about fifteen or twenty meters deep. If you continue to dig, you may find the soil layer or the rock layer." ωωw..net
Du Dayong sounded a little confused, but he still understood the general meaning.
"And the collapse distance here is too long. This is because someone deliberately removed the support wood. As long as explosives are placed in a deeper place, the outside will almost collapse like now. Then what is blocked inside will be buried by the collapse.
Otherwise, the oxygen will be depleted and the person will suffocate and die."
The two engineers spoke expressionlessly, but Du Dayong hated Cui Erquan in his heart.
Because this mine was the cemetery left by Cui Erquan to Cui Dazhu's family and Luo Jiahui's family at that time. The family named Liu should have followed it to get a bargain, or they had followed Cui Dazhu after promising some benefits.
At four o'clock in the afternoon, we finally saw the skeletons, and they were very concentrated. Eleven skeletons of different sizes and shapes were scattered in the uncollapsed area of the passage.
Du Dayong knew that these dozen people were suffocated here, rather than buried directly, because there were many stones behind the pile of bones. The place where the stones were piled was at the end, and there was a passage and
The entrance passage of the mine has a curvature of 120 degrees.
After all the bones were cleared out, the two engineers decided not to come tomorrow, so they decided to go in in the dark and have a look.
Du Dayong, He Wuwei, and Qiao Chuan also followed in at this time.
