The extensive mining situation that has a significant impact on the environment will quickly disappear. To achieve sustainable development in the mining industry, it is necessary to adopt an intensive, refined, and environmentally friendly development model in order to achieve the successful construction of green mines!
How to solve problems and promote the construction of green mines
1. Land resources and geological disaster prevention
Mining operations are carried out strictly in accordance with the design, with sequential mining from top to bottom in steps. Dangerous rocks on the slope and loose stones are promptly removed, and overly steep slope angles are corrected to prevent geological disasters such as collapses and landslides.
During the mining process, real-time monitoring technology is applied to establish a dynamic monitoring system.
During the accumulation process of the temporary dumping site, timely slope cutting and toe pressing measures should be taken to prevent the occurrence of geological disasters.
2. Utilization of Solid Waste
During the mining process of open-pit mines, losses of ore are inevitable. Ore losses refer to the situation where ore remains in the mining site and is not extracted, or is lost during the processes of mining, transportation, and disposal. The principle of continuously improving recovery rate and comprehensively reducing tailings should be followed. The block selection mining technology should be adopted.

Collect the stone chips and stone dust generated from the processing of ores, and store and sell them in categories for comprehensive utilization. For instance, the stone chips and stone dust can be used as desulfurization absorbents or raw materials for cement plants.
3 Wastewater Treatment
To address the wastewater generated during the processing and screening of mines, a hierarchical treatment approach can be adopted, and a dedicated wastewater treatment system can be constructed.
4 Dust Control
The control of dust pollution can be achieved from two aspects: overall dust pollution prevention and control in quarries, and dust prevention and control at the source points.
Overall dust pollution prevention and control in the quarry:
By arranging the paths for exploration and the positions of the shafts, and optimizing the mining procedures, the dust pollution can be reduced at the overall design level.
Adopting energy-saving and environmentally-friendly blasting technology, optimizing blasting technical parameters, and reducing dust emissions from blasting.

According to the characteristics of dust from different sources and the amount of dust, corresponding dust removal systems are provided to control the dust.
5 Noise Control
During the installation of the equipment foundation, advanced technologies should be employed for vibration reduction, noise reduction and sound insulation; and the maintenance and upkeep of the equipment should also be strengthened.
Employ multi-row hole delayed blasting and multi-stage blasting, reduce the amount of explosives used in each section, and minimize the impact of blasting noise on sensitive areas.
The workshop adopts a fully enclosed technology, ensuring that all equipment with high noise levels are concentrated in a sealed building, and setting up soundproof rooms for the operators' work areas and other places.
6. Environmental protection measures during the construction period
(1) Arrange the construction plan reasonably and optimize the construction scheme. Avoid construction during rainy days and windy weather to reduce the amount of soil erosion; cover the building materials that are prone to causing dust.
(2) Construction wastewater and domestic waste are treated centrally. Discharge and littering are strictly prohibited; the site will be cleared and vegetation will be restored promptly after the construction is completed.
(3) Conduct reasonable construction layout and meticulously organize construction management. Minimize and effectively control the scope and degree of impact on the ecological environment of the construction area.
(4) Establish strict construction operation procedures and establish an ecological environment supervision system during the construction period. Prohibit construction vehicles from arbitrarily creating construction access roads.
The extensive and environmentally significant mining practices will soon disappear. To achieve sustainable development in the mining industry, a model that is intensive, refined and environmentally friendly must be adopted. Only in this way can the construction of a "green mine" be successfully accomplished!
