Sand and gravel mine environmental protection measures and ecological harmony

Mine environment refers to the collection of atmospheric environment, surface water environment, groundwater environment, acoustic environment, ecological diversity and other environmental elements affected by mining activities. The problem of mine environmental protection is the environmental evolution, destruction and pollution caused by the interaction and influence between mining activities and environment.

The environmental protection measures of sand and gravel mines are mainly aimed at the mining process and production process, and it is necessary to strengthen the management of waste gas, wastewater, noise, solid waste and the ecological environment, as well as the prevention and balance of the impact on biodiversity. At the same time, combined with the application of new technology in the monitoring of the mine ecological environment, the overall control system for environmental protection is formed. Through environmental monitoring, the current situation of environmental quality and the development trend of ecological impact are accurately, timely and comprehensively reflected, and scientific basis is provided for the mine environmental management, control and supervision of pollution sources.

In the mining process, the adoption of new blasting technology, such as differential control technology, electronic control energy concentrated release technology, etc., through the adoption of precision measures, the use of blasting powder reduction method, and the selection of fully automated water mist humidification dust removal, acoustic atomization dust removal, magnetized water dust removal, pre-charged high-efficiency spray dust removal technology, can effectively reduce the generation of dust in the mining process; In production, the establishment of a fully closed processing plant, equipped with an efficient dust collection system, is conducive to the implementation of dust suppression and dust reduction measures in the plant; The mining area does not set up an open storage yard, and the loading and unloading of the storage yard are all carried out in a closed environment to eliminate air pollution. For the treatment of wastewater, in the mining process, 100% recycling is adopted, and at the same time, it can be fully combined with mine water as a supplement. Domestic water in the mining area can be used for afforestation and other utilization measures after harmless disposal, meeting the requirements of five hundred and one hundred indicators, dust pollution control and 100% do not constitute a source of pollution affecting air environment indicators. The domestic sewage treatment and harmless rate is 100%, the surface water environmental quality is 100%, the wastewater recycling rate is 100%, and the sludge harmless treatment and utilization rate is 100%.

In the process of ore mining, low noise equipment is selected, damping material, isolation material and silencer are installed on the equipment to reduce the generation of noise sources. At the same time, the mining area should strengthen the construction of isolation belt with the surrounding villages or residential areas, and reasonably adjust and manage the production and transportation time to avoid disturbing the people; The adoption of a fully closed aggregate processing plant equipped with soundproof materials can maximize the control of the noise generated in the production process, control the noise within a reasonable range to the greatest extent, and do a good job of co-construction, co-creation and co-grasp of ecological civilization through enterprise-local harmony measures and close contact with the party building base in the mine.

Solid waste and garbage in mining areas and living areas are classified and stored and managed according to industry and life, and the side and residual materials in mining and production processes have achieved 100% resource utilization. The main source of industrial solid waste is to solve the harmless disposal of chemical substances such as waste oil of engineering equipment and energy storage batteries, and special closed storage places should be set up to mark hazardous waste. Entrust a qualified third party for centralized processing; Domestic refuse should be transferred to the municipal centralized refuse transfer station for unified disposal; Treat from the source and adopt systematic and process-based disposal measures, leaving no hidden dangers; Through the establishment of a garden type mining area, it actively becomes a display window of the place.

In view of the problems that the exploitation and exploitation of mineral resources may damage the vegetation of the mine and its vicinity, affect the living environment of organisms, and bring hidden dangers to the regional species diversity, long-term monitoring of the ecological environment of the mining area can be conducted to timely detect potential harmful and toxic substances, avoid ecological pollution and environmental impact, and effectively control and improve the ecological environment of the mining area and its vicinity. To provide a normal space for the survival and development of living things; The changes in the species of animals and plants in the mining area indirectly reveal the changes in the survival factors of the mining area (such as air and water source), which is also one of the goals of environmental protection of the sand and gravel mine, that is, to strengthen the protection of biodiversity in the mining area and nearby areas, and is also an important reflection of whether the atmospheric environment and water environment are destroyed.
