Abstract

The number of coal mines in China has been reduced from 87000 in 1995 to about 10000 in 2015, some of the closed coal mines have been incorporated into bigger coal corporations, and others become abandoned coal mines. Such abandoned coal mines hidden disasters as old goafs water disaster, instability disaster by large scale goafs collapse, coal spontaneous combustion and poisonous or harmful gas disaster in goafs, spontaneous combustion disaster of coal waste piles, land pollution of mining area, destruction of ecological environment have been important factors that influencing safety production and social lives. In order to promote ecological civilization construction and improve the comprehensive control technology level of abandoned coal mines hidden disasters, the paper analyzed the characteristics and comprehensive control technologies progress, systematically discussed the feasibility of hidden disasters detection, monitoring and forecasting, comprehensive control and utilization for abandoned coal mines. The results showed that the hidden disasters comprehensive control technologies were mainly including data platform construction of hidden disasters factors detection, monitoring and forecasting platform construction (goaf instability and collapse monitoring, underground water level and quality monitoring, temperature and spontaneous combustion monitoring, toxic and harmful gases monitoring, ecological environment monitoring), comprehensive control and utilization (ecological restoration effect evaluation, gas reserves prediction and drainage effect evaluation, underground space comprehensive utilization of abandoned coal mines). With the introduction of data platform construction and cloud computing, the comprehensive control of abandoned coal mines hidden disasters can be automatically, effectively and in real time.
