Traditional mining area shifts its focus to improving environment

Longquan Buddha Cultural Garden is a cluster of temples, recreational areas and treefilled fields about 9 kilometers from downtown Taiyuan, the largest city in coal-rich Shanxi province. It is a popular spot for residents to enjoy the outdoors on a sunny afternoon.

Seeing it today, it’s hard to imagine that as little as five years ago the entire area was covered in toxic waste.

For five decades after 1962, the 14.3-hectare site in Shentanggou village was used to dump 4.5 million metric tons of waste from the Xiyu Coal Mine.

Spontaneous fires were common, while strong winds would often send dust flying and contaminating the air, water and soil, according to Wang Kechao, head of the mine, which is part of Shanxi Zhenghua Group.

In 2009, to bring the severe pollution under control, Wang said, the company teamed up with the Shanxi government in a cleanup drive that included compacting the waste, laying down clean soil and introducing seepage controls.

“The beautiful garden and new temples have been built for residents and visitors, making it a new attraction,” Wang said, adding that visitors to the nearby hot springs have also increased since the cleanup.

This year, the government of Shanxi, the country’s major coal supplier, said it plans to spend 2 billion yuan ($300 million) to start another 53 projects that will turn coal wastelands into desirable environments.

He Tiancai, solid waste generated by industry, and is now recovering contaminated areas in order to protect the environment,” vicegovernor He Tiancai said on Sept 12 at the Trans-Century Tour of Chinese Environmental Protection, an event organized by the Environment and Resources Committee of the National People’s Congress.

By the end of 2015, Shanxi had 270 billion tons of known coal reserves, accounting for 17.3 percent of the national total, the third-largest after the Inner Mongolia and Xinjiang Uygur autonomous regions.

Decades of mining and industrial production have generated huge amounts of solid waste, mainly coal gangue — a waste product from the extraction process — as well as slag, devulcanized gypsum and fine particles called fly ash that are expelled in flue gases, all of which get into the air, water and soil.

The province cut coal output by 143 million tons last year, which directly reduced coal gangue by 14 million tons, according to government data.

“We also saw 66.1 percent of solid waste processed in 2016, an increase of 44.1 percentage points from 2005,” He said. “By 2020, it will rise to 70 percent.”
