Problem and Countermeasure for Safety and Environmental Issues of Closed Small Coal Mines

We analyze the geological environment issues, the social issues, flooding, and geological disasters caused by the closed small coal mines based on the investigation of the cases that occurred in recent years. The strategies to tackle the issues are presented based on the analysis, to clearly identify the responsibility for the safety and environment of the closed small coal mines, to create an overall plan and a long term mechanism for the environment protection, to create the top-level design of the safety and environment protection based the assessment of each case, to define special safety measures for the major issues, and to adopt variety of methods to recover the social environment.
