Abandoned quarries in Jiaozuo city turned into National Mining Park
  • Apr 03 , 2023

Beishan, also known as Phoenix Mountain, is located in the north of Jiaozuo City, Henan Province. From the 1980s to the mid-1990s, there were 12 quarries nearby, which seriously damaged the surrounding ecological environment.

In 1999, the Jiaozuo Municipal People's Government shut down all quarries near Beishan.

In 2005, the municipal government began to build Beishan Park, and installed a stainless steel surgical needle sculpture, the Sewing Needle, on the top of Phoenix Mountain. The sculpture is crescent-shaped, 20 meters high, 0.8 meters in diameter, and weighs 10 tons. In 2007, "Beishan Park" was renamed "Fengshan Park".

In June 2005, the Zhejiang University team submitted the "Beishan Park Abandoned Mine Rock Slope Treatment and Biological Protection Engineering Design Plan". In September, the geological environment treatment and Spraying greening project of the central slope of the quarry in the park started operation, and the mountain slope of more than 20,000 square meters in the central area was cut and reinforced and greening. For sections that are locally unstable after slope cutting and clearing, bolt network reinforcement and local frame slope protection reinforcement works are carried out to ensure the overall stability of the slope.

In order to ensure the safety and stability of the slope treatment, the construction party graded the crushed stones and rocks and pressed them at the foot of the slope, and then covered them with soil and sprayed them for greening. At the same time, considering the sightseeing needs of park visitors, an uphill passage and platform are opened on the slope.

The greening of the rocky slope in the central area of the park mainly uses the thick-layer base material spraying greening technology. According to different site conditions, the base material with a thickness of 8 to 15 cm is mixed with more than 10 vegetation such as black locust, amorpha, horse thorn, wattle, and chrysanthemum. The seed mixture is sprayed onto the slope, which solves the problem that plants cannot grow on the high and steep rocky slopes of quarries in the Central Plains. At the same time, local container seedlings with strong stress resistance and good landscape effects were planted in good time.

After two months of restoration and treatment, the slope surface seemed to be covered with a thin layer of green carpet; three months later, the vegetation began to grow luxuriantly; one and a half years after the regreening construction, the multi-level three-dimensional greening of trees, shrubs and grasses presented a nearly natural growth state. The satellite photo taken on March 25, 2010 (four years after regreening) shows that the green sea of plants in the Fengshan park mining area is completely integrated with the surrounding mountain landscape. The ecological restoration of the bottom of the park mining area after 10 years shows the effect of ecological restoration based on nature and harmonious coexistence.

Today, Seam Mountain Park has become a comprehensive mine park that focuses on the display of environmental renewal and ecological restoration methods such as limestone mining relics and ground subsidence relics, and integrates ancient porcelain kiln relics, modern film and television city and other cultural landscapes. It was opened in 2010 In May 2008, and was rated as the second batch of national mine parks by the Ministry of Land and Resources.
