石灰岩矿山地质及资源问题与恢复治理研究

Research on Geology and Resource Problems and Restoration and Treatment of Limestone Mines

石灰岩矿作为一种不可或缺的矿产资源,被广泛开采并应用在各项工程活动中。随着对矿产资源的开发利用,无序非法的矿山开采会对当地的生态环境造成严重破坏。因此,如何有效进行石灰岩矿山生态修复已成为矿山领域的研究热点。基于国家大力推进矿山遗迹地生态修复的研究背景,通过调查大量矿山以及查阅相关文献,总结了目前石灰岩矿山主要存在的地质及资源问题与恢复治理技术,并对存在的不足和发展趋势提出了几点思考。最终展望性提出了地质灾害隐患消除—生态地质环境评价—立地类型划分—选区试验—土壤重构—植被重建—后期管护的石灰岩矿山生态修复新模式,以期为石灰岩矿山治理提供理论参考。

As an indispensable mineral resource,limestone mine is widely mined and applied in various engineering activities.With the development and utilization of mineral resources,disorderly and illegal mining will cause serious damage to the local ecological environment.Therefore,how to effectively carry out ecological restoration of limestone mines has become a research hotspot in the field of mining.Based on the research background of vigorously promoting the ecological restoration of mine relics,the main geological and resource problems and restoration and treatment technology of limestone mines were summarized by investigating a large number of mines and consulting relevant literature,and some thoughts on its shortcomings and development trend was put forward.Finally,a new model of ecological restoration of limestone mines was proposed,which included the elimination of hidden dangers of geological disasters,the evaluation of ecological geological environment,the division of site types,the test of selected areas,the reconstruction of soil,the reconstruction of vegetation and the later management and protection,in order to provide theoretical reference for the management of limestone mines.
