Overview of mine pollution sources

1, mine air pollution from coal-fired air pollution mainly of boilers, furnaces, stove, canteen stove exhaust gas discharged to the atmosphere and the coal dust escape in screening and crushing reproduced during storage, especially in open ground The coal storage yard will generate dust when it encounters windy weather. The main coal-fired sectors in the mine include the coal screening plant screening workshop, the raw coal storage warehouse, the loading warehouse, the open-pit coal storage site, and the main room. In addition, the road will also generate dust.

2. Wastewater discharge Mine sewage mainly includes mining sewage, coal-sewage sewage and other auxiliary industrial sewage and domestic sewage. With the production of mines, a large amount of mine water will be discharged, and some will be returned to the underground for use after treatment. Other parts will cause water pollution if left untreated. If the coal preparation plant does not have a special tailings water treatment system, the suspended solids will greatly exceed the standard. The place where the mine water flows will not only cause environmental pollution, but also cause crop production to be reduced or even rejected.

3. Solid waste discharge The solid waste brought by the mine during coal production and processing is mainly coal gangue. Except for a small amount of utilization, these coal gangues are piled up near the mines, which not only occupies a large area of ​​land, but also has a large thermal energy in the burnt body of the waste rock. It is easy to spontaneously ignite and emit secondary pollution when exposed to water.

4. Noise pollution Mine noise mainly comes from different degrees of noise generated by equipment during coal production, processing and transportation. Noise sources are mainly divided into three categories. 1. Aerodynamic noise mainly comes from main fan, air compressor, blower, vacuum pump and so on. 2. Mechanical noise mainly comes from the impact of materials and tanks in crushers , vibrating screens, jigs, centrifuges and chutes. 3. Electromagnetic noise comes from generators, electric welders, etc.

Elastic Warping Machine

The Elastic Warping Machine, also known as spandex warping machine, is a textile machine used to produce elastic fabrics. It is designed to warp a wide range of elastic materials, including spandex, Lycra, and other stretchable fibers.

The machine consists of a creel, a warp beam, a tension control system, and a warping section. The creel holds the spools of elastic yarn, which are then fed into the warping section. The tension control system ensures that the yarn is evenly distributed and maintains a consistent tension throughout the process.

The warping section consists of a series of rollers that pull the yarn through a series of guides and onto the warp beam. The elastic yarn is then wound onto the warp beam, creating a tightly-woven fabric that can stretch and recover without losing its shape.

The Elastic Warping Machine is widely used in the production of a variety of elastic fabrics, including swimwear, athletic wear, lingerie, and medical garments. It is a highly efficient and cost-effective way to produce high-quality elastic fabrics with consistent performance and durability.
