Abstract

Based on the analysis of goaf disaster accidents and main types, the goaf disaster characteristics are analyzed, the control countermeasures and suggestions are proposed. The results show that the goaf disasters are divided into four types according to the disaster forms in resources integration coal mines, that is, the abandoned old goaf or pit shaft permeable, goaf fire including coal combustion and gas explosion, the poisonous and harmful gas in goaf emission, the adverse abnormal geological disaster. The goaf has the characteristics of unknown distribution, different kinds of disaster types, concealment and happened suddenly, unpredictable. The control countermeasures principle are summarized and proposed, including ground survey in advance, underground detection following up, hazard assessment and evaluation in time, comprehensive control for disaster reduction, monitoring and supervisory in place, safety measures for guarantee.
- resources integration coal mine,
- old goaf,
- ground survey,
- underground detection,
- monitoring,
- disaster prevention and control
