Experiments on the diffusion patterns of coal gangue-based grout in goaves under varying rock particle sizes and grout mass fractions

Experiments on the diffusion patterns of coal gangue-based grout in goaves under varying rock particle sizes and grout mass fractions

ObjectiveInvestigating grout diffusion patterns and predicting the grouting range hold great significance for coal gangue grouting and filling engineering in goaves. Specifically, they are significant for designing grouting hole and row spacing, guiding grouting construction, determining the groutin...
