What are the environmental impacts of natural sand and gravel mining, artificial sand instead of
In recent years, the application of sand production line equipment momentum hot, in fact, reflects another situation: natural sand and gravel continue to reduce as well as the past natural sand and gravel in the mining process caused great damage to the environment, so that China's policy is constantly adjusted to the direction of encouraging the production of artificial sand tilt. What is the impact of natural sand and gravel mining on the environment, where are the advantages of artificial sand to replace natural sand, these are also people who want to invest in mechanism sand equipment need to have some knowledge. Therefore, in considering what can be used to replace the problem of natural sand, the only way to solve the problem of sand and gravel demand at present is through the path of artificial sand production. Artificial sand is not a material invented by artificial creation, the source of artificial sand is still from the nature of the available ores and gravel material, only through the sand making machine and other special equipment for manufacturing sand and gravel material to achieve the purpose of producing sand. This is also the meaning of the term artificial sand. Facts have proved that, through the use of stone crusher sand making machine and other such artificial sand equipment, out of the sand and gravel material is almost comparable to the state and nature of natural sand, therefore, this is also a major reason why the sand and gravel production line equipment has been widely used in recent years.
Artificial sand production line site
According to the concrete material gradation and natural material gradation balance, when there is a
gradation adjustment and balance facilities (crushing), the total amount of general mining area
planning for the amount of material 1. 15 ~ 1.5 times (quarry reserves for the amount of 1.5 ~ 2.0
times), raw materials containing mud, sand rate is more than the larger value. When there is no
gradation adjustment facility, according to the natural material is less of a grain size material for
planning the mining range.
Most of the natural sand and gravel materials in the sand and gravel production line are on the river bank or bank slope, and the mining process causes pollution to the environment, mainly including: cover stripping and stacking, production drainage, waste oil, sand and dust, noise, bank slope stabilization and soil erosion. Measures to be taken include:
1、Rational planning of slag dump and slag utilization and stockpiling.
2、Rational design of excavation slopes and control of soil erosion.
3, the periphery of the mining area to set up water interception, drainage ditches.
4、Construction surface drainage is discharged after precipitation treatment.
The control measures for noise, dust, waste gas, waste water and waste oil in the sand and gravel
production line include:
1、Select low-noise crusher equipment and process to control the noise generated at the
constructi site.
2、Dusty working surface and road surface are fully sprinkled with water to avoid the construction
site and motor vehicles from generating dust during operation.
What are the aspects of the impact of natural sand and gravel mining on the environment, the advantages of artificial sand instead of natural sand have been briefly introduced above. From the environmental protection point of view, the main problem is the diffusion and collection of dust. Artificial sand advantages exist, but how to utilize the good, it is mastered in the production enterprise management cognition, we also hope that the development of the same time do not ignore the environmental impact of the aspect of the environment to the environment.
