On February 24, the reporter learned from the Green Mining Online Salon of China Mining Federation that up to now, the ecological big data platform of Mengcao Mine has covered more than 60000 mines across the country, including not only basic mine information such as mining time, mine closing time, mine type, longitude and latitude coordinates, but also local climate, native animals and plants, as well as statistical analysis of soil, applied restoration technology, standardized process of restoration, etc. The technical experience of mine restoration accumulated by Mengcao provides an operable and standardized procedure for the ecological restoration of similar mines in the future.
Hao Yuanyuan, general manager of Mengcao Life Community Big Data Company, said that there are misunderstandings in mine ecological restoration. Sometimes the greening of the surface does not mean that the ecology is good, but it is the damage to the ecosystem. For example, if you plant a tree species that should not be planted, you will not be aware of its negative impact on groundwater in a short time. It will take a long time to find that the plants are gradually reduced., The ecological environment is degraded again, this result runs counter to the concept of ecological restoration. Ecosystem restoration is not only the greening of the surface, but also the return of wild animals such as rabbits and foxes to restore the original ecological scene. Therefore, the research and data accumulation of mine ecological background is necessary and plays an important role in ecological restoration.
Data Map
Different from the traditional Internet of things, the company manually collects information on native soil, watershed, meteorology, microorganisms, animals and plants, etc., and makes a detailed survey to build a solid mine ecological background, which provides a basis for future restoration.
It is reported that the resource management of the traditional mine management mode is scattered, especially for large and medium-sized mining enterprises. The mines are fragmented and distributed in various places, which can not easily know the information of each mine, resulting in isolated islands of data and information. The resulting problem is that emergency management and daily coordination are highly dependent on people, which directly affects the real-time and accuracy of information, resulting in slow decision-making and low efficiency of enterprises. The construction of intelligent mine is the application of scientific and technological means to enable the mine to realize intelligent management through information empowerment.
Regarding the one-time investment in the construction of smart mines that many people are worried about, Hao Yuanyuan explained that from the perspective of the length of mine production time, the accumulated labor cost, time cost, and management cost of the traditional mine management model are all very high.
Hao Yuanyuan said that there are three main steps in building smart mines. The first step is to build a mine intelligent nervous system. Through the installation of cameras and sensors, the data can be updated and traceable, which can not only detect illegal mining, but also give early warning to abnormal data, so as to make decisions in advance and take timely countermeasures. The second step is to build a three-dimensional geological model of the mine. The construction of a three-dimensional geological model of the mine is a true simulation of the mine ecological environment, which can help managers save time for site exploration. For example, slope is an important technical parameter for mine restoration. Different slopes correspond to different restoration technologies. Through the three-dimensional geological model, the staff can complete multi-directional slope measurement without going to the site, mark the expected slope and dangerous slope, and directly check the effect after slope repair. Earthwork calculation is also an important work for ecological restoration. Using the three-dimensional geological model, it can not only calculate the earthwork volume of plane terrain and inclined terrain in real time, but also adjust according to different heights to calculate the corresponding earthwork volume. The third step is to build a mine big data platform. Taking the ecological big data platform of Mengcao Mine as an example, there are not only the classification of mineral business and soil type, but also the information of local water, soil and gas, native plants in the stages of pre-mining, mining and post-mining restoration, which are gathered on the platform in the form of videos, pictures and data, so as to realize information sharing, evidence-based and efficient command. Moreover, through the later data tracking analysis, but also to grasp the actual effect of ecological restoration.
