Generally, because concrete has massive compression strength and steel has incredible tensile strength. Combined, they make amazingly strong structures.
The winding house houses the engine that raises and lowers the mine's cage (lift).
The design life of steel structures can vary depending on factors such as the quality of material used, level of maintenance, and exposure to environmental conditions. Generally, steel structures are designed to have a service life of around 50-100 years. However, with proper maintenance and periodic inspections, the lifespan can be extended beyond this range.
