Quantitative research on sensitive factors of coal wall rib spalling in full mechanized caving face with large mining height
With the advancement of equipment technology, the mining height of coal mine working faces has been increasing year by year. In thick coal seams with high mining heights, the frequent occurrence of rib spalling in coal faces has become a prominent issue, leading to unclear mechanisms and increased difficulty in controlling rib spalling. This paper employs a comprehensive approach combining theoretical analysis, physical experiments, numerical simulation, and mathematical statistics to investigate the influencing factors of rib spalling in coal faces. An orthogonal experimental model for coal face rib spalling is established, quantifying each influencing factor and ranking their sensitivity. Consequently, control strategies for rib spalling in fully mechanized top coal caving faces of thick coal seams are proposed. These findings provide valuable insights for managing rib spalling in similar conditions with high mining heights and offer guidance for selecting control factors against rib spalling.
