Abstract: The purpose of this study was to explore the effective prevention and control method of ground fissures in plain coal mining subsidence. Firstly, the model experiment was carried out, and then two typical working faces, working face A (WF A ) and working face B (WF B ), in the Huaibei plain mining area were selected for the case study of the moisturization method. Model experimental results show that water content had a significant effect on cohesive soil fissure development, and the results of the case study show that the humidification method could effectively reduce the development degree of ground fissures. Therefore, this study provided a new approach for the effective prevention and control of ground fissures in plain coal mining subsidence.
