【 摘 要 】

The abandoned coal mine hidden disasters have been important factors that influencing safety production and social lives. Based on the analysis of the types of hidden disasters in abandoned coal mines and their impacts on the environment, the exploration techniques and methods of goafs and water hazards, spontaneous combustion or fire area distribution in abandoned mines are discussed systematically, and the monitoring and forecasting technologies for the instability of abandoned goafs and subsidence disasters, mine groundwater level changes and water pollution disasters, spontaneous combustion and gas pollution disasters, mining ecological environment disasters are proposed. Then the environmental engineering problems caused by abandoned coal mines, the comprehensive prevention and control methods, and the technologies of grading utilization of abandoned coal mines are put forward. The conclusions are shown as follows: Firstly, the hidden disasters of abandoned coal mines mainly include such six disasters as the goaf instability and collapse disasters, old goaf water accumulation disasters, mine groundwater level drop and water pollution disasters, spontaneous combustion and gas pollution disasters in the goaf, coal waste dump and backfill areas spontaneous disasters, secondary disasters caused by geological and environmental damage; secondly, the environmental engineering issues induced by abandoned coal mines include three aspects: living environment problems, working environment problems and ecological environment problems; thirdly, the utilization of abandoned coal mines is mainly divided into three aspects: gas drainage and utilization, comprehensive utilization of underground space, and comprehensive utilization of surface.
