Mine ecological restoration is a vivid practice of ecological civilization construction.
Once dependent on the mountains to eat the mountains today to protect the mountains
In the golden autumn, at the project site of the fifth phase of the mining management area in the east of Sanhe, Langfang City, dozens of excavators, transport vehicles and rollers shuttle back and forth, and the sound of the machine is rumbling. The living trees and shrubs that have been planted are full of green, in sharp contrast to the bare grey soil next to them.
It is expected that by the end of this year, the city has been mined for more than 40 years, an area of 22 square kilometers of abandoned mines will be covered with green.
"Relying on the mountain to eat, one side of the soil and water to nourish one side of the people." Many years ago, Hebei, as a major mining province, had 20,000 mines when it was "high light". With rich mining resources, the people in many places in Hebei have filled the "money bag", but they have also lost the "good days" : mountain destruction, vegetation damage, river pollution, and accidents.
"We will resolutely oppose indiscriminate mining practices that lack management, are reckless and damage the environment, and resolutely shut down mines that seriously damage groundwater and the ecological environment." The provincial Party committee and the provincial government have repeatedly emphasized environmental problems in mines.
The management of mine reduction shall be implemented, and the power of examination and approval shall be received in accordance with the law. In 2018, the provincial Party Committee and the provincial government issued important documents such as the Opinions on Reforming and Improving the Mineral Resource Management System and Strengthening the Comprehensive Management of the Mine Environment to strictly control the development and utilization of mineral resources in the province and strengthen the comprehensive management of the ecological environment.
In the same year, Hebei launched a three-year combat plan for continuous pollution remediation of open-pit mines, which clearly required the use of two years to continue to stop production and remediation of 1024 certified open-pit mines that did not meet the standards. In the course of three years, a total of 2,002 (an area of 145,100 mu) responsible for the loss of mine land were comprehensively treated through restoration of greening, transformation and utilization, and natural restoration. It is planned that by the end of 2020, the comprehensive treatment rate of the responsible body's lost mine land (based on the results of the 2015 mining environment survey in Hebei Province) will reach more than 50%.
From the point to the line, from the line to the surface, the province's mining environment improvement has been strongly promoted. Zhangjiakou City put forward the construction target of "no ore city"; Chengde, Tangshan self-pressure, improve environmental standards and rectification standards, and comprehensively promote the construction of green mines; Qinhuangdao city combined with the construction of the whole region of tourism city, in-depth promotion of open-pit mine improvement, mining enterprises that fail to meet the standards to be firmly shut down.
After continuous attacks, Hebei has made remarkable achievements in mountain management and mountain protection. By the end of August this year, the number of solid mines in the province had decreased from 10,367 in 2001 to 2,186 at present. A total of 2,704 open pit mine sites, 145,000 mu of which were lost to the main greening responsibility subjects, were repaired; 58 mines in the province have been recognized as green mines by the state.
A variety of models to achieve diversification of investment
Green is the base color of mine environmental treatment and restoration.
Recently, in the Qinglong Manchu Autonomous County Maquan Town Guangcaigou village mine treatment and restoration site, I saw more than 200 meters long hillside was divided into a uniform size grid by network cable, each grid has more than 70 bags filled with soil, grass seeds and shrub seeds. The bags are surrounded by a lot of green grass, and the once bare mountain has come back to life.
This is a vegetation restoration technique for rock slopes called plant biobags. The vegetation can be restored to green in the same year, which can effectively protect the slope and dust, and the subsequent treatment effect is good.
Not only Qinhuangdao, Tangshan City is also through the greening of vegetation, to achieve environmental management and restoration of mines, and cultivate "ecological flowers". The city focuses on nature reserves, scenic spots, water source protection areas, both sides of the main traffic arteries (railways, expressways) and the surrounding built-up areas of the city (town), and coordinates the restoration and management of the historic mine land, and this year will complete the greening management task of 100 responsible bodies for the loss of mines, achieving a green area of 51,700 mu.
