Strength Deterioration and Sensitivity Analysis of Coal Samples Under Different Immersion Times for Underground Water Reservoirs

In the coal pillar dam of underground water reservoirs, groundwater exerts a certain degree of dissolution and erosion on the coal body, inducing the development of internal cracks and the deterioration of its mechanical properties. To this end, coal samples with varying moisture contents were prepa...
