摘要
Abstract
Aiming at the spontaneous combustion prevention and control requirements of the No.9 coal seam in Yuanbaowan Coal Mine,a dynamic model of oxygen concentration gradient diffusion and temperature variation in the goaf was established based on multi-physics coupling theory.Through Fluent simulations,a multi-factor sensitivity analysis was conducted on the evolution characteristics of oxygen concentration under three conditions:upper and lower corner sealing,lower corner nitrogen injection,and the combined action of nitrogen injection and sealing.A multi-source fusion monitoring system,dynamic pressure-balancing ventilation regulation in open areas,continuous nitrogen injection into the goaf,and inhibiting foam coverage were integrated to construct a three-dimensional fire prevention and extinguishing system for the fully mechanized top-coal caving face,forming a combination of fire prevention and extinguishing technologies with regional adaptability.关键词
