基于综合效益评价的采煤塌陷地复垦模式的设计

Design of rehabilitation mode for coal mining induced subsidence areas based on comprehensive benefit assessment

介绍了采煤塌陷地复垦模式的总体情况,建立了塌陷地复垦模式综合效益评价指标体系,运用评价模型,对积水较深的塌陷地、积水较浅或季节性积水的塌陷地、无积水塌陷地3种情况下,4种典型复垦模式的综合效益进行了评价。根据评价结果,结合徐州市九里区的特点,对九里区采煤塌陷地复垦模式进行了总体设计,并在以上研究的基础上对各复垦模式提出了若干建议。

On presenting overall information of coal mining induced subsidence area rehabilitation mode,the article establishes a comprehensive benefit assessment index system for the rehabilitation of coal mining induced subsidence areas.Comprehensive benefit assessment is carried out on four different rehabilitation modes for subsidence areas with varied scenarios such as deep wter,shallow water,seasonal ponding and no water.Based on these assessments combined with characteristics of Jiuliqu of Xuzhou,a comprehensive rehabilitation design is worked out for the Jiuliqu mining induced subsidence area on the basis of which a series of recommendations are proposed on the rehabilitation modes.
