Exhibition reinvigorates ex-coal mine

Spoil tips greened, sewage pits cleaned, 4.5 million tons of detritus removed

An area of subsidence-hit waste ground that was formerly a coal mine has been transformed into a venue for the recently opened Tangshan International Horticultural Exposition.

More than a century of coal extraction had left the site, now known as South Lake Park, strewed with countless pits, according to Yao Shan-yong, deputy director of the coal-mining technology department at Kailuan Group Limited Liability Corporation, which operated the mine.

These pits were used to dump rubble and construction waste in the aftermath of a disastrous magnitude-7.8 earthquake in 1976 that leveled 97 percent of Tangshan's buildings and killed more than 200,000 people.

Zhang Wenming, head of South Lake Park's Administrative Committee, said the area became an eyesore known as "waste mountain".

This started to change in the 1990s, when subsidence had eased enough for low-rise buildings to be built and some small-scale voluntary tree planting to take place.

"A lot of waste was dumped in the pits and surrounding areas," said Zhang.

"Tangshan is a city born of coal-mining that lived on steelmaking, but this gave people the impression of a polluted city.

"The successful bid to host the exposition brought Tangshan new drive."

Hong Jinxiang, the committee official in charge of the park's greening work, said more than 1.4 million square meters of land had been planted with trees and grasses in the past few years, while 4.5 million metric tons of accumulated waste had also been removed.

"We made use of the former sewage pits and spoil tips to make the clear lakes and green mountains that a park needs," Hong said.

The park's Longshan and Fenghuangtai mountains were both former spoil tips that have been treated and greened, Hong said.

What they say

We are busier than before due to the increasing number of vehicles on the roads since people from all around the country have started to visit the exposition. However, I'm proud that my hometown can be world-known thanks to it.

Xu Jialiang, officer with the Tangshan Traffic Management Bureau

Design work started in 2013 when the South Lake Park had already undergone years of ecological construction. Tangshan, as the first prefecture-level city to host the horticultural exposition, really made great efforts for the transformation.

People like me feel really thankful for the horticultural exposition. Without it, the park might still be surrounded by garbage. It's a refreshing change.

I was born the year after the quake of 1976. My mom didn't allow me to come to the South Lake area as a child, she said it was dirty. But now I often take my 70-year-old mom to the park for walks. She says it is unbelievable that the waste mountain could change into a scenic spot.
