【 摘 要 】

The disaster and environmental engineering issues induced by coal mine goafs instability have become one of most important problems threatening safety production and the safty of cicizens. Based on the analysis of instablility modes of coal mine goafs, the disaster types and environmental engineering issues were researched. The results showed that, firstly, there are six types of instability modes, that is, the goafs instability under the influnce of single pillar, geological structures, goafs water, mining disturbance, static load and dynamic load. Secondly, There are two main types of disasters induced by coal mine goafs instability, and one refers to the damages of surrounding buildings and structures, mine earthquake and ecologically envirenmental damages caused by coal mine goafs instability and ground collapse; The other one refers to equipment damage and workers hazards caused by undermine roof impact. Thirdly, the environmental engineering issues involves three espects: the living environment, the ecological envrionment and the working envrionment. For these three environmental problems, this paper puts forward specific solutions and suggestions.
