Project Overview
Shenhua Group, one of the world's largest coal companies, has long faced problems such as coal dust pollution and coal freezing in winter at its Bayannur coal mine's open-pit coal yard, which seriously affects coal quality and transportation efficiency. The coal yard covers approximately 15,000 square meters. To achieve green production, Shenhua Group decided to carry out a complete enclosure renovation of the coal yard.
Challenges
01
The winter temperatures in Bayannur are extremely low, reaching as low as -30°C, making ordinary membrane materials brittle and unusable.
02
The coal mine is located in an area with strong winds and sandstorms, which makes it easy for sand to accumulate on the surface of the membrane material, affecting the airtightness and service life of the air-supported membrane structure.
03
Coal yards have a large coal turnover rate, and the enclosure renovation should minimize the impact on coal transportation.
Solution
Supai customized the SP-MC150 cold-resistant and wind-blown sand-resistant air-supported membrane coal storage system for them. This system uses low-temperature resistant PVDF membrane material, allowing normal operation in environments as low as -40℃; it is equipped with an automatic sand removal system that periodically cleans accumulated sand from the membrane surface; and it adopts a segmented installation method, allowing for gradual modification without affecting coal transportation. A key highlight of the solution is the application of "hot air de-icing" technology, which rapidly melts ice on the membrane surface in winter, ensuring the normal operation of the air-supported membrane structure. Simultaneously, the air-supported membrane structure achieves an IP65 sealing performance, effectively preventing coal dust leakage.
