Environmental issues highlight that the stone mining industry should keep pace with the times

China's stone resources reserves are the world's number one, and stone materials consumption is also the world's number one. A considerable number of mining enterprises “fully utilize” China's rich stone resources, indiscriminately excavating, unrestrained, destructive and even devastating plundering of resources, while stone as a non-renewable resource is wasted a lot, leading to some excellent stone resources in China. Already near exhaustion. Due to various reasons, the mine is disorderly mining. While destroying the forest vegetation, the dust, wastewater (stucco) and noise generated by the processing of stone increase the deterioration of the ecological environment. At the same time, due to the failure to pay attention to the safety of the mining process and improper mining methods, Has caused a lot of accidents, can not help but make people feel chilling.

The environmental problems of quarrying industry are highlighted
The quarrying industry, as one of the industrial chains of the household industry, has caused people to smell "stone" because of its "high pollution and high energy consumption".

Mineral rock has become an important resource for human infrastructure for thousands of years. The scale of modern industry faces many problems, such as the enormous pressure on the environment caused by the limestone quarrying industry.

waste water disposal
Almost all stone mining industry processes produce large amounts of wastewater, and the limestone quarrying industry is no exception. Water is used in a wide range of applications, such as high pressure jets and lubrication of solid cutting tools. Wastewater can be recycled to a limited extent, but will eventually become sewage. Contaminants include unnatural materials such as oil and natural gas that are used during machinery, and also contain excessive amounts of natural deposits.

Substance precipitation
The wastewater discharge entrains high sediment content. As the sediment downstream begins to accumulate, the aquatic species begin to calcify the environment. Calcium carbonate is an important mineral in limestone and many are found to be formed by animals, especially hard and bivalve molluscs. Excessive calcium carbonate can be dangerous.

Groundwater level drop
Limestone needs to dissolve minerals in the water, which means that many limestone quarries must have water pumped out to wash the sediment. Excessive pumping will lower the water table. If a coal mine is close to the coast, the depletion of groundwater will cause salt water to invade the inland. Natural hot springs supplied by groundwater will dry up due to reduced pressure, and may also cause damage to ecosystems and even human water shortages.

Noise and air pollution
The two atmospheric environmental impacts of the limestone quarrying industry are the noise of mining machinery and the high dust in the air. Depending on the direction of the wind and the surrounding vegetation, dust in the air can drift with the wind to areas dozens of miles from the mine, affecting the health of the local population, especially for those who have problems with the lungs. Noise pollution from heavy-duty machines in quarries can scare away local wildlife.

The quarrying industry should keep pace with the times
The “low-carbon life”, “low-carbon economy”, “low-carbon...” vocabulary that advocates people to work and live in a way that saves energy and reduces emissions has gradually become familiar.

The quarrying industry keeps pace with the times and highlights the openness of the ideological line. Advancing with the times indicates that people must have a world vision and a strategic vision. When analyzing problems and solving problems, they must focus on the domestic and the world; they must focus on reality and the future. Only by combining these requirements organically and understanding the overall situation can we ensure the scientificity and predictability of decision-making. The ideological line itself is an open, not closed, system that will continue to evolve as practice evolves.
