Need to soon clarify the phenomenon of land subsidence at Trai Cau

For many years, scientists and professional agencies of Thai Nguyen province have not discovered the cause of land subsidence, and cracked the door at Trai Cau village, Cay Thi commune, Dong Hy district, to make more than a hundred households here always worry about every day when the field cracks a lot more every day and it is very difficult to grow rice.

Whenever there is a subsidence phenomenon, people report to commune and district officials to make a report to the superior, but no agency has responded to the cause of subsidence to reimburse the people.

Trai Cau village, Cay Thi commune is predominantly San Diu ethnic people, they have settled for a long time, the main job is to cultivate and intensify wet rice.

Cracks are increasingly spreading

Since 2006, Thac Lac 3 mine (which is a mining pit of iron ore of Trai Cau iron mine of Thai Nguyen Iron and Steel Company), has a mining position close to the adjacent fields of Trai Cau expansion to expand production. , exploiting the depth of ore taking, is also when the rice fields of the people here are always in shortage of water.

The water caught in the field during the day and night but it was only a few hours and it was really empty. The groundwater flows a lot, people catch water to the field only a few days when the land is dry, lose water quickly, the soil is poor, the rice productivity is reduced.

Mr. Lai Van Nguyen, Head of Trai Cau village, said that the phenomenon of land subsidence has occurred since the end of 2006 and is still happening on a large scale with increasing levels of danger , the whole village of Trai Cau has 130 households. 100 households with subsidence have a big impact on crops, 18 households have been affected on houses, water wells have been exhausted, lots of grounds, kitchen, walls are cracked, more than 20ha of fertile soil is used to support her I am deserted because of lack of water.

Take us to the fields currently grown corn, beans, peanuts (because of dehydration cracking can not grow rice), only look at the cracks with a few dozen meters long each road, sometimes there are large holes like the mouth of a well Deep down to 4-6m, Mr. Nguyen lamented: "The water flowing down these holes is never full, how many grasses and garbage thrown there are also" missing ", afraid of having the bamboo fenced off. It is dangerous for children and cattle, but every year its mouth is bigger, it is likely to swallow up the production land of its relatives ".

The subsidence pits with a length of over 1m, cracks 3-5cm wide, running around in the field, the plowing season catches water flowing forever and full, how much fertilizer ash of the field is washed away, the cracks have withdrawn the entire floor. surface water, making farming extremely difficult.

Leaky pit at Mr. Lai Van Nam's family's plot with diameter up to 15m, deep 3-4m. At first, the slump was only 6-7m wide, but the soil and crops were pulled down gradually, so both households lost their farming fields. Mr. Lai Van Quy, whose rice fields are more than 2 acres, is now forced to switch to growing beans, because the sinking pit has deformed the fields, becomes a pan-shaped shape, warping fields, not having the same volume of water to grow rice.

Right next to the edge of the mining pits, these deep and wide fish ponds have been cracked all the way down, the holes collapsed more than 5 meters wide, about 3 meters wide, the grass has grown green. Afraid of cows and buffaloes, pigs and chickens fell into this hole, people brought bamboo fins to a fence. On the nearby tea garden, there was a grade 4 house built by Pham Thi Bich who had been abandoned for more than 3 years because the wall was cracked, the landlord was too afraid to move to the neighbor to buy land to build a house.

Ms. Pham Thi Bich said, " In the past , there was only a cracked house, shallow water well, but after a night of waking up, the fish pond was running out of water, there was no fish left. To move immediately to the head of the temporary village, more than 10 households who could not escape, lived in a state of confusion, not only houses but also constructions were affected.

The subsidence of this land has been going on for several years, many officials from the province to the district come to Trai Cau village many times, but no one can tell the cause from where. Because of that reason, the people here are complaining, they leave the field and go to work as hired labor . "

The phenomenon of land subsidence in Trai Cau area, which has occurred since 2006, continues to occur on a large scale seriously affecting the lives and production of local people. For a long time, due to the absence of official conclusions from the authorities about the cause of land subsidence and dehydration, people were extremely confused and worried; Compensation and support for affected people are also not available.

Therefore, the determination of the cause of the land subsidence and dehydration phenomenon in Trai Cau is very important in developing compensation plans, helping local people to stabilize their lives soon.
