山东废弃石灰岩矿山地质环境特征与治理恢复探索

GEOLOGICAL ENVIRONMENT CHARACTERISTICS OF ABANDONED LIMESTONE MINES IN SHANDONG PROVINCE:Management and Restoration Exploration

通过对历史上长期不合理露天开采的山东废弃石灰岩矿山的调查研究,发现石灰岩矿山广泛分布于鲁西地区、鲁中南区,生态环境破坏较严重.采石弃渣多形成"裙"状弃渣坡、"帐"状弃渣堆及高陡型弃渣坡,基岩裸露且裂隙发育,在集中降雨条件下极易引发泥石流、崩塌等地质灾害.结合济南章丘市某废弃石灰岩矿山复绿项目的工程实践,总结出以工程措施为主,兼顾生态恢复的地质环境综合治理恢复经验,具有一定的推广价值.

With investigation and study on the abandoned limestone minesin Shandong Province due to long-term unreasonable exploitation in history,it is found that the ecological environment of the mines widely distributed in the west and middle-south of Shandong have been seriously destroyed.The waste slag after quarrying are mostly piled into skirt-like slopes,tent-like heaps and high-steep slopes.With exposed bedrock and developed fissures,they will easily trigger debris flow and slide under concentrated rainfall conditions.Combined with the revirescence project practice of certain abandoned limestone mine in Zhangqiu city,the papers ummarizes a comprehensive treatment and restoration experience on geologica lenvironment dominated by engineering measures,while taking into account ecological restoration,which would be a certain promotional value.
