3. Exploring the Pattern of Bottom-Slab Water Emergence The absence of water-conducting channels does not exclude the risk of water emergence, and the presence of a large number of damaged structures in the basement rock can promote the formation of water-conducting channels. Damage structure affects the performance of the coal seam floor’s water barrier layer, which leads to changes in the activation of the small hidden faults and the water damage law.

3.2. Images Obtained with Solutions of Different Surfactants at Different Flow Rates Pulverized coal migrates and flows with water or surfactant solution in propped fractures. When the migration of some coal particles is blocked by pore cracks, they deposit and block the fracture. As shown in Figure 6, These cracks that intercept pulverized coal are shrinking pore throat channels. Due to the shrinkage of the width of the channel, the pulverized coal forms a bridging blockage at the pore throat.
