Buying and selling sand is illegal and may be suspected of illegal business operation. This crime refers to one of the following illegal business practices in violation of state regulations. (a) without permission, the franchise, monopoly of goods or other restricted goods as stipulated by laws and administrative regulations; (2) buying and selling import and export licenses, import and export certificates of origin and other business licenses or approval documents stipulated by laws and administrative regulations; (three) without the approval of the relevant competent departments of the state, illegally engaged in securities, futures, insurance business or illegally engaged in fund settlement business; (four) engaged in other illegal business activities, disrupting the market order, and the circumstances are serious. Whether it is illegal to buy or sell illegally exploited river sand depends on the business amount: 1, the illegal business amount of individuals is more than 50 thousand yuan, and the illegal business amount of units is more than150 thousand yuan; 2, the amount of illegal income of individuals is more than twenty thousand yuan, and the amount of illegal income of units is more than fifty thousand yuan.
River sand is a kind of nonmetallic ore with complex composition, smooth surface and high impurity content, which is produced by repeated collision and friction of natural stones under the action of water for a long time. River sand particles are smooth, relatively clean and widely available; River sand has no taste, while sea sand has salty taste.
The main component of sand is silicon dioxide (SiO2). Sand consists of minerals and tiny rock fragments, which are formed by the erosion and weathering of rocks. The composition of sand varies from place to place, depending on the source and conditions of local rocks.
Harm of indiscriminate sand mining
Excessive excavation of river sand will make the river embankment unprotected, and it will be soaked by high water level in rainy season, which may lead to the collapse of the river embankment and flood. Excessive excavation of river sand will make the river bed full of deep pits, make the water flow form a vortex, and affect the safety of the waterway. Excessive excavation of river sand will destroy the river bed, harm aquatic animals and plants and affect the ecological environment.
It is easy to destroy the original structure of the river bed, cause soil erosion and destroy the ecological environment. Sand is a common building material, and relevant certificates are needed when buying and selling. Therefore, it is legal to buy and sell sand with legal documents, and vice versa. The most common component in sand is silica, which usually exists in a timely form. Because of its stable chemical properties, hard texture and weathering resistance. To put it simply, the reason why the state prohibits sand mining is for environmental protection and safety, in which environmental factors account for a large proportion.
