靖远矿区地面塌陷地裂缝特征与治理研究

The characteristic of ground collapse and ground fissure and treatment research in Jingyuan mining area

在研究靖远矿区地质环境的基础上,较为详细地叙述了地面塌陷、地裂缝地质灾害发育特征,对地面塌陷进行了分区稳定性分析评价和地裂缝稳定性分析,针对不同灾害类型、区段,提出了回填、夯填、耕地恢复等治理建议。

Based on the expounding about the geological conditions in Jingyuan mining area, the author explains detailedly the actualities of ground collapse and the geological hazards of ground fissure, carry on the district stability analysis about the ground collapse and the stability analysis about the ground fissure. Focused on the different type and partition of the hazards, the author raised some control design proposal, for example backfill, backfill tamper and second ploughing.
