  Coal resource storage is a core component of coal mine production, providing buffer support for production systems while enabling precise utilization of coal quality through categorized storage. With advancements in coal storage technology, its role in environmental protection and efficiency enhancement has become increasingly prominent, serving as a vital pillar for enterprise transformation. 1. Evolution of Mainstream Coal Storage Methods After multiple rounds of technological innovation, current mainstream storage methods have diversified into four primary categories: （ 1 ） Open-Air Storage Yards:  This involves storing coal resources outdoors, once the dominant choice for early coal enterprises but now largely phased out. （ 2 ） Semi-Open Storage Yards:  Also known as dry coal sheds, these are widely adopted by coal enterprises in southern China. Given the abundant rainfall in southern coal mining regions, this storage method—which combines protection with ventilatio...

The Volgograd Football Stadium in Russia is shaped like an inverted truncated cone. The facade is designed based on a solemn image of salute. The entire building's diamond-shaped structure is composed of a steel shell, branching upwards from the top of lower diamond modules, forming smaller cross-sections that intersect at higher points, creating a magnificent pattern reminiscent of a rocket taking off. Due to the most intensive organization and development of the site and plot, this project makes the most efficient use of land resources. The spaces between the steel reinforcements of the facade shell are filled with stainless steel mesh, giving the stadium a unique aesthetic appearance and also serving as windbreaks for spectator lounges and entrance halls. The stadium's design considers the needs of people with mobility impairments. For example, it includes 460 seats for disabled people and provides high-sound-pressure speakers and a system to transmit sound signals to hearin...

 Routine maintenance of steel structures should focus on structural safety, corrosion protection, and the maintenance of connection components. Specific measures are as follows: 1. Routine Inspection and Maintenance Inspect components such as supports and purlins for deformation, corrosion, or loosening, with particular attention to the tightness of bolted connections. ‌ The thickness of the roof insulation layer must meet standards to prevent condensation, which can cause prolonged moisture exposure and corrosion of metal components. 2. Corrosion Protection: Promptly repair areas with peeling paint or rust. Prioritize the use of anti-corrosion paint or spray coatings for protection, ensuring the metal surface is clean and dry. Maintenance of Special Components Supports and sliding ball joints: Regularly lubricate moving parts (such as sliding ball joints) using molybdenum disulfide grease to reduce the coefficient of friction and maintain smooth rotation. ‌ Check that drainage ar...

  Laminated glass is a type of safety glass made by bonding two or more sheets of glass together with a transparent interlayer. Thanks to this interlayer, when laminated glass shatters upon impact, the glass fragments remain bonded together. The fragments remain adhered to the interlayer film rather than scattering, minimizing the risk of injury. Even after breaking, the glass retains a certain degree of visibility, thereby providing a protective barrier. Laminated glass offers transparency, sound insulation, and safety. Compared to ordinary glass, it has distinct advantages in protecting both people and property. (1) Safety: The safety characteristics of laminated glass are demonstrated through its impact resistance, penetration resistance, and wind pressure resistance. When laminated glass breaks, the interlayer holds the glass fragments in place, preventing shards from scattering and causing injury or property damage. Laminated glass outperforms tempered glass in withstanding h...

The Volgograd Football Stadium in Russia is shaped like an inverted truncated cone. The building’s facade was designed based on the image of a solemn salute. The entire diamond-shaped structure consists of a reinforced concrete shell. From the tops of the lower-level diamond modules, branches with smaller cross-sections extend upward, intersecting at higher elevations to create a magnificent pattern reminiscent of a rocket launch. Thanks to the highly compact organization and development of the site and plot, this project maximizes the efficient use of land resources. The spaces between the steel beams of the building’s facade shell are filled with stainless steel mesh, giving the entire stadium a unique aesthetic appearance while also serving as a windbreak for spectator lounges and lobbies. The design of the stadium takes into account the needs of people with mobility impairments. For example, it features 460 seats designated for people with disabilities, as well as high-sound-press...

 Spatial structures have become a widely adopted structural form in recent years. Composed of bolt-ball nodes and seamless steel tubular members, these highly indeterminate structures are assembled using high-strength bolts or welding connections. They are characterized by a low steel-to-span ratio, excellent seismic resistance, short construction cycles, and aesthetic appeal. These structures are extensively utilized in large-span engineering projects, such as sports stadiums, airport terminals, high-speed railway stations, industrial plants, and large-scale storage warehouses. However, during the actual production, fabrication, and installation processes, two key factors can still significantly impact the overall quality of bolt-ball space frame structures. (1) Insufficient Strength of High-Strength Bolts In bolt-ball space frame structures, the strength of the high-strength bolts (which are capable of bearing significantly higher loads compared to standard bolts of the same si...
