Land subsidence in Bac Kan

More than a month after the incident, land subsidence in Pan Son, Ban Giang, Luong Thuong commune, Na Ri district (Bac Kan), people still simmered in anxiety .

Lo day, lo night!

At the end of the house, Mr. Nguyen Cong Ngoan (Pan Sa village, Luong Thuong commune, Na Ri district) showed me the 5-7cm wide cracks on the floor. He used a wooden stick to poke through the cracks, the deepest place measuring up to 80cm. 'Sleeping nights, just a small noise is the family of fire.' According to him, the crack became longer and longer so the whole family became more worried.

This country is not only Ngoan Ngo's house like that. About 200m away, Hoang Cong Chinh's family house now has to " cut off " more than 10m ² because " it is an insecure area ", he said. Mr. Chinh told that the cracks in the cement floor in the unstable area were only as small as crow's feet, but gradually the cracks widened and ran for several meters, then the floor surface began to sag. The house owner confirmed that the house phenomenon was cracked and people worried about the night. 'Nearly a month has passed but no unit in the province has confirmed the reason why. All the people get is still the words of encouragement . the incident happened to the government newspaper '?!

There are only two households of Mr. Hoang Van District, Mr. Be Van Toc, who moved to other places.

According to the report of Na Ri District People's Committee, after the collapse and subsidence occurred in late December 2006 to mid-January 2007, there were more and more landslides and land subsidence in the field, the level of influence was wide diameter up to 0.5km. Initial statistics temporarily determine that nearly 40 households have a cracked house, nearly 12 hectares of cultivated fields are subsided and cracked.

People take care of their own accommodation?

Of the two households with houses in the fields forced to move to avoid risks, each household was supported 5 million VND.At the moment, only Mr. Hoang Van Quan has moved temporarily to the village cultural house.Mr. Bu Van Toc's household temporarily moved his belongings but could not manage his own accommodation.

Mr. Nguyen Duy Cau, Luong Thuong commune Party Committee Secretary, affirmed 'the slow move for the remaining households because this household has not been able to contact relatives to create a new place ?!' Still following him. However, the movement is mainly due to the households' self-concern because currently the commune does not have a land fund to arrange.

Mr. Tran Nguyen, deputy director of Bac Kan Department of Natural Resources and Environment, affirmed that subsidence can be caused by opening gold mining pits too deep, sinking groundwater, leading to landslides.'It is not possible to determine the exact extent and extent of influence so it is impossible to anticipate how large the area of ​​subsidence and subsidence can be anticipated,' said Nguyen. According to the record of Tuoi Tre, there are placer gold mining sites near the plunging and subsidence areas, with exploitation points to a depth of over 20m.

Talking with Youth , Bac Kan Provincial People's Committee Vice Chairman Nguyen Van Thanh affirmed that in the short term, the province requires two gold mining units to stop exploiting at the present depth.

According to Mr. Thanh, the province will have a specific plan, when the specialized agency of the University of Mining and Geology gives a conclusion. In case the ground is not guaranteed, there will be a plan to move the number of households in unsafe areas on the basis of relocation, keep the cultivated land intact.
