Collapse of mined-out area is an environmental geological hazard of the coal mining area.

采空区塌陷属于煤矿区的环境地质灾害问题。

The origin of the hazard is the disordered mining of coal pits along a river, and geological and environmental factors are the necessary conditions of the hazard.

沿河小煤窑的无序开采是这种地质灾害产生的根源，而地质及环境因素是灾害产生的必要条件。

With the increase of geological hazard in recent years, the issue of geological environmental data management has been becoming far more pivotal.

随着近几年地质灾害的增多，地质环境数据的管理问题也日益凸显其重要性。
