Hydraulic Properties for Predicting Water Inrush from Mine Floors

A 723.7 KB document by Lihong Shi, last updated May 2026, presents a numerical simulation model for studying hydraulic conductivity in mining failure zones. The model simulates pore-fracture porous media to analyze water pressure and flow velocity distribution under different fracture parameters. It provides a method for calculating the hydraulic conductivity of floor fracture zones in coal mines.

Use Cases

• Modeling water pressure distribution in mining failure zones based on fracture structure parameters.
• Simulating groundwater flow velocity in fractured rock masses under different permeability conditions.
• Predicting water inrush risk from mine floors based on hydraulic conductivity calculations.
• Comparing pressure gradients between fractures and surrounding porous rock mass.

Strengths

• The model is validated against actual floor pressure distribution, as mentioned in the description.
• The simulation approach simplifies the calculation of resistance in complex pore-fracture media.

Limitations

• The dataset is a 723.7 KB DOCX file, suggesting limited scope and potentially no raw numerical data.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
