Performance and backfilling process design of coal-based solid waste paste under conditions of constant temperature, humidity, and variable pressure

Key Points

• Performance of coal-based solid waste paste is influenced by variable pressure conditions, and temperature-humidity factors play a crucial role.
• Notably, experiments indicated significant changes in paste performance metrics under variable conditions, especially concerning backfilling efficiency.
• The analysis highlights the importance of understanding solid waste behavior during the backfilling process, particularly how environmental factors affect its stability.
• These findings may inform improvements in backfilling methods, underscoring the need for ongoing investigation into solid waste paste technology.
