Undermining China: Towns sink after mines close

People in Helin village are fighting a losing battle as the ground beneath them crumbles: patching up cracks.

This photo taken on July 7, 2016 shows residents making their way through a flooded street in Wuhan, in central China's Hubei province. Flooding is common during the summer monsoon season in southern China, but rainfall has been particularly heavy this year and many areas have been lashed by torrential rains this week. Picture: AFP.

CHINA - Deep in the coal heartlands of northern Shanxi province, people in Helin village are fighting a losing battle as the ground beneath them crumbles: patching up cracks, rebuilding walls and filling in sinkholes caused by decades of coal mining.

Around 100 pits in Helin, buried in the hilly rural outskirts of the city of Xiaoyi, have been exhausted, and cluttered hamlets totter precariously on the brittle slopes of mines.

But while local authorities have begun evacuating hundreds of thousands of residents most at risk elsewhere in Shanxi province, Helin's situation - though serious - isn't yet considered a priority.

"We haven't been told to leave yet, but when the government gives us the order, we'll be happy to go," said Wang Junqi, who lives in a one-room tenement with his family. "It isn't safe here and the people who have a bit of money have already gone. It's scary, but what can we do?"

Mines that burrowed under villages and towns during China's three-decade coal boom have left the authorities with the need to evacuate hundreds of communities in danger of sinking.

Shanxi province alone plans to move 655,000 residents by the end of next year from unsafe old mining regions, with the cost of relocation estimated at $2.37 billion. The Shanxi government estimates coal mining has cost the province 77 billion yuan in "environmental economic losses".

GEOLOGICAL DISASTERS

Mine-induced subsidence is not unique to China, but its problems dwarf those of other countries.

A notice board at a deserted Communist Party building in an abandoned village not far from Helin gives an idea of the scale of the disaster.

According to official data, coal mining had already caused as many 26,000 geological disasters by the end of 2014, and as much as 10,000 square kilometres of land has been affected, an area the size of Gambia in Africa, according to some estimates.

China's land ministry said last month it would spend $11.27 billion over the next five years to restore mined land and treat mining waste nationwide.

The growing environmental bill comes at a time when China's stricken coal sector faces mounting debts, falling demand and a long-term decline in prices after the boom turned into a bust.

BOON TO BURDEN

The coal sector, as with other basic industries in China such as steel, is now saddled with overcapacity estimated at around 2 billion tonnes a year, as demand growth slows and the country promotes cleaner forms of energy. China planned to close around 1,000 collieries this year alone, many of them in residential areas such as Helin, as it cuts coal's share of total energy consumption to 62 percent by 2020.

During the boom years, as prices and profits soared, miners were encouraged to dig further and deeper, encroaching upon residential areas and farmland.

While large state-run firms would often relocate entire villages, smaller private miners, chasing quick profits, simply dug under and around communities. With mining tax revenues surging, local governments were reluctant to impose stricter controls on the industry.

The industry helped pay for construction binges like one in Xiaoyi, where Helin is located, topping up local government tax coffers and bestowing the city center with rows of largely unoccupied luxury apartment blocks.

What was once a boon for governments has now turned into a burden: Xiaoyi has already spent more than $901.31 million to treat subsidence, the government said. Together with the neighbouring city of Luliang, it plans to relocate as many as 230,000 people over 2014-2017.

Little of the money to move communities and restore the land is coming from the miners themselves, although that was supposed to be the plan in the beginning.

Miners are required to pay "subsidence fees" to pay for the clean-up when their mines close. The Datong Coal Industry Group (601001.SS), the only state miner to give breakdowns, paid just 1.4 million yuan in those fees from January to March this year, or 0.04 percent of its total costs, according to its quarterly report.
