Sorting out the mode of mine ecological restoration and activation utilization

(2) Biville Quarry Recreation area

Biville quarry is located in the Grand Canyon of Clivertine, France, which has the characteristics of large scale, large elevation difference and serious ecological degradation. Through platform transformation, vegetation restoration, water flow introduction and other technical means, the project creates the waterfront habitat, and turns the former quarry into a regional fishing mecca and lake leisure area.

Taking advantage of the original topography of the mine, the project uses a series of facilities and equipment to direct the flow of water to the valley floor to form a lake. The platform transformation of the straight-line quarry pit is not only convenient for visitors, but also allows the runoff from the high level to flow from the grass into the drainage ditch, protecting the surface from the impact of rain, runoff and erosion. On this basis, the introduction of broom, vitex and other barren resistance, strong root system, strong nitrogen fixation, through plant roots to promote the surface firm, the formation of topsoil. Considering the great demand of local residents for fishing, the huge lake shoreline at the bottom of the valley has been carefully designed to facilitate fishing.

(3) Kinta Nature Park

Kinta Nature Park is located in Malaysia, with a low environmental impact means to promote ecological restoration, the introduction of tourism and resort functions to balance ecological protection and regional development, the ecological environment is extremely harsh open lead mine into a country park with both protection and recreation functions.

The project focuses on biological natural restoration, promoting soil self-purification and vegetation regeneration, and creating wetlands to provide habitats for microbial reproduction. At the same time, pay attention to the play of tourism and vacation functions, combine the inherent resources in the park with tourism, transform the use of lead mine ruins, abandoned factory buildings as scenic spots and visitor centers, build natural education and field practice facilities, as well as bird's nests, sightseeing towers, camping and shelters. Activities such as watching wild animals and birds, sketching, photography, going out, visiting lakes and hiking in the wild are launched to achieve the common development goals of ecological restoration and economic development.

2.2 Heritage memorial model

On the basis of ecological restoration, the heritage memorial model highlights the landscape of industrial and mining areas, focuses on reflecting the mining scene, and transforms abandoned mines into urban industrial civilization memory sites, heritage parks, museums and other popular science cultural facilities as well as industrial tourism destinations.

(1) Quarry of Dionysus

The quarry of Dionysus in Greece was built in the 15th century. The project adopts a low impact method, from design to construction, without too much modification and processing, and reflects the original style of the quarry to the maximum extent.

The project uses local materials, makes full use of the original site materials, organizes the tour path through the old quarry walking path, transforms the abandoned land into an open-air museum, and provides visitors with a scene space to reproduce the traditional marble development and excavation.

(2) Chenshan Botanical Garden Mine Garden

The Mine Garden of Chenshan Botanical Garden is located in Shanghai, on a 70-meter-high hill in Chenshan. In 1905, Chenshan began quarrying, until 2000, Chenshan quarry was closed by the government, many years of mining formed a huge mine. Based on the concept of "minimal intervention", after six years of cleaning, planning and vegetation planting, the project transformed the new landmark and city card of Shanghai with 1.6 million adult visitors.

Shentan area is the core of the mine garden, which was formerly the remains of Chenshan Quarry. After the entire southern slope of Chenshan was mined for building stone, it was dug deep underground, reaching more than 60 meters into the ground, and the pool water is more than 30 meters from the ground, and the deepest depth of the pool water is more than 30 meters. Within the pit area, the designers have created a walkway consisting of poured steel barrels, a steel trestle fitted to the cliff, an artificial "one-line sky" and a wooden pontoon bridge, to experience the visual impact of the pit quarry up close and experience the spectacular spectacle of the artificial waterfall.

2.3 Recycling mode

The regeneration and utilization mode fully exploits the location value of the mining area, strengthens the topographic features such as cliffs and cliffs in the original mining area, transforms the original mining land into functional Spaces such as sports venues and high-end resort hotels with unique spatial experience, and reshapes the vitality of the region.

(1) Braga Municipal Stadium

Located on the site of the former Montecastro Granite quarry in Portugal, the Braga Municipal Stadium takes full advantage of the cliff topography of the quarry to boost the economy and support future growth in a deprived part of the city by embedding a large-scale sports facility.
