摘要
煤矿开采引起的河堤变形与破坏显著降低了其防洪安全性能。“先破坏、后治理”的传统处理方式存在修复滞后、防汛压力大的问题,具有较大的安全隐患,甚至诱发溃坝、洪水等重大公共安全事故。边采边复,及时恢复河堤的防洪能力是解决这一问题的主要技术途径。基于矿山开采沉陷动态过程特征,提出了沉陷区河堤边采边复的设计流程;构建了河堤治理过程中的动态填方量计算模型,并应用于某矿地表河流的河堤采动损害治理工程中。研究结果表明:采用边采边复的治理方式对沉陷区河堤进行治理,可以降低在采动过程中的河水外溢风险,同时减轻了采动损害对河堤的破坏程度;提出的动态填方量预计方法可实现对河堤各治理阶段土方量的准确预计,能够满足实际工程需求,为河堤治理工程设计提供了依据。
The deformation and destruction of river embankment caused by coal mining significantly reduce its flood con-trol safety performance.The traditional treatment method of"first destroy and then treat"has the problems of delayed repair and heavy flood control pressure,which has great potential safety hazards and even induces dam break,flood and other major public safety accidents.The main technical way to solve this problem is to restore the flood control capacity of the river em-bankment in time while mining.Based on the dynamic process characteristics of mining subsidence,this paper presents the de-sign process of concurrent mining and reclamation of the river embankment in subsidence areas;the calculation model of dy-namic fill volume in the process of river embankment treatment is constructed and applied to a treatment project about the river embankment suffered the mining damage.The results show that the risk of river overflow in the process of mining can be re-duced,and the damage degree of the river embankment caused by mining damage can be alleviated by using the method of con-current mining and reclamation to restore the river embankment in the subsidence area;the proposed method of dynamic fill volume prediction can accurately predict the earthwork volume in each treatment stage of embankment treatment,meet the actu-al engineering needs,and provide a basis for the design of embankment treatment engineering.
