摘要
土岭高岭土矿在以往开采过程中,因未严格按设计排土,由此而诱发产生的排土场边坡滑移、泥石流以及地表生态环境破坏等矿山地质环境问题日益突出,严重危害坡下矿区公路以及周围居民生命财产安全。本文在现场地质调查的基础上并依据已有矿山工程资料,首先分析了该排土场可能存在的几种滑移破坏模式,然后对其整体和局部稳定性进行了力学计算与评价。综合考虑该排土场地形地貌、地层岩性以及稳定性分析结果等,本着技术可行、经济合理的原则,提出了"削方减载+浆砌石挡土墙支挡+浆砌石骨架植草护坡+截排水+监测"等综合性防治工程方案。本方案实施后并通过两个水文年的监测,其稳定性状况良好。通过本方案的实施,不仅有效地消除了该排土场地质灾害安全隐患,而且还全面恢复了其生态环境。
Because Tuling kaolin mine not strictly dumped according to the design in past mining process,it is made the mine geological environment problems produced by the dump,such as landslide and debris flow and ecological environment destruction,etc,are increasing sharply.It will directly constitute a serious threat for mine highway,the lives and property of the local residents.On the basis of field investigation and the mine engineering material,firstly the sliding failure modes of the dump are analyzed,and then the integral and local stabilities of the dump are calculated.Comprehensive considering the topography and stratigraphic lithology of the dump,the stability analysis results,etc,in accordance with the principle of the feasible in technology and reasonable in economy,the comprehensive control project scheme is put forward,namely ＂cutting slope and reducing load＋masonry retaining wall＋masonry skeleton plant grass＋cut drainage＋monitoring＂.After the scheme is implemented,already through the monitoring of two hydrological year,and the stability of the dump is in good condition.The implementation of the scheme not only effectively eliminates the geological disaster safe hidden trouble of the dump,but also fully recovers the ecological environment of the dump.
