AI Technical Summary
Existing technologies are insufficient to achieve uniform gas mitigation across the entire thickness of thick coal seams. Traditional negative pressure pre-extraction and permeability enhancement measures are ineffective, and single gas injection displacement technology is inefficient and cannot meet the gas control needs of high-intensity mining. There is a lack of simulation methods to simulate the synergistic effect of large-scale gas reduction and displacement and pressure-driven gas displacement.
A physical simulation test system integrating gas reduction and displacement with pressure displacement was designed. The system integrates extraction, displacement, and gas reduction material injection into a single simulation platform, including a coal seam simulation module, a gas injection module, a displacement module, a gas reduction material injection module, and a gas extraction module. The system achieves coupled testing of extraction, displacement, and gas reduction material injection through modular design.
This study achieved a refined description of the integrated and uniform gas reduction and decongestion mechanism of pressure-driven gas control, constructed a physical simulation test platform for the synergistic effect of pressure-driven gas reduction and decongestion, filled the equipment gap in related technologies, provided key experimental means and theoretical support for gas decongestion in thick coal seams, and ensured the safe and efficient mining of deep coal seams.
