山东郓城县城区地质环境“孤岛”问题初探

Preliminary exploration of geological environment"isolated island"problem in urban area of Yuncheng County,Shandong Province

郓城县作为“孤岛”矿区城市,城市地质环境问题主要表现为采矿塌陷、地表水质变化、地下水流场变化、空气污染、坑口电厂及煤化工企业综合影响等一系列问题,矿震的复合作用也有可能威胁到城市建筑物安全。文章分析了郓城县城市地质环境影响因素并对未来发展趋势进行了预测,对采煤塌陷地的变化、地下水环境影响、空气质量变化等分别进行了论述,提出了开展郓城县城市环境地质调查评价和建设城市地质环境监测网建议。

As a city of"isolated island"mining area,Yuncheng County's urban geological environment mainly faces such problems as mining collapse,changes in surface water quality and groundwater flow field,air pollution,comprehensive impacts of pithead power plants and coal chemical enterprises,and so on.The combined effect of mining earthquakes may also threaten the safety of urban buildings.This paper analyzes the influencing factors of urban geological environment and predicts the future development trend in Yuncheng County.It discusses the changes in coal mining collapse areas,impact on groundwater environment,and changes in air quality.Suggestions are put forth regarding urban environmental geological survey and evaluation,and the establishment of an urban geological environment monitoring network in Yuncheng County.
