Mines susceptible to compound hazards are often characterized by highly water-rich confined aquifers and hard, thick sandstone roofs. When the goaf reaches a certain scale, the instability of overlying strata is accompanied by a sharp increase in water inflow, posing dual risks of water inrush and rockburst. Integrating theoretical analysis, similarity simulation, and numerical modeling, this study explores rational mining layout schemes under the synergistic objective of rockburst prevention and water control. First, based on overburden movement characteristics and microseismic event distribution patterns, the stability of the high-position confined aquifer key stratum was assessed, revealing the risk of fracturing and instability in the water-rich stratum under current mining scales. Subsequently, reasonable ranges for key parameters of the mining layout were determined through theoretical calculations, and the stress field, energy evolution, and plastic zone development of different schemes were compared and analyzed. Finally, the Support Vector Machine (SVM) method was applied to quantitatively evaluate the synergistic effectiveness of rockburst prevention and water control across different schemes, leading to the identification of an optimal mining layout for compound hazards mines. This provides theoretical guidance for the coordinated prevention and control of rockburst and water inrush hazards.
