In recent years, the coal industry has become a benchmark for leading the construction of green, low-carbon, and sustainable development by implementing the sustainable development concept of resource conservation and environmental friendliness, and developing green buildings. This article analyzes the application of green and energy-saving technologies, materials, and processes in the construction process of mining buildings, calculates the added value of investment and energy consumption separately, and quantifies them to form investment increment and benefit increment. With the help of economic evaluation models, it demonstrates the economic rationality of achieving zero carbon buildings in coal mines.
