| 摘 要： | 在分析邳州石膏矿地面塌陷机理的基础上,从土层因素、矿层因素和地下水因素3个方面建立了评价指标体系。利用两级综合评判的理论和方法,对邳州石膏矿地面塌陷进行了分区预测,形成了易发性分区图。预测结果和实际情况能够较好地吻合,可作为邳州石膏矿区进行采矿地面塌陷地质灾害的防治依据。

| Abstract: | Based on the analysis of surface collapse mechanism for Pizhou gypsum mine, the authors set up an evaluation index system in terms of soil layer factor, ore bed factor and groundwater factor, made a partition prediction to surface collapse for Pizhou gypsum mine with the use of the theory of two levels of comprehensive evaluation, formed susceptibility zonation map. It was concluded that the prediction results matched the present situation and could be served as prevention bases for surface collapse of Pizhou gypsum mine. |
