在我国大型露天煤田开发中，常常有多家煤炭企业进入同一煤田，各煤炭企业均是一个开发主体，对国家划拨条区煤炭资源进行开采，同时或先后建设几个露天矿。相邻露天矿在开采作业过程中所形成相邻端帮因受两矿采动影响较大，易发生滑坡灾害，尤其是相邻端帮到界边坡。胜利西二号露天煤矿和乌兰图嘎锗煤露天矿为同一煤田相邻露天矿，两矿采矿权在相邻端帮处不重合，致使西二露天矿西帮和锗煤露天矿东帮之间形成一个梯形台体，受下覆断层破碎带及两矿作业影响，台体内出现底臌、裂缝、断层垮塌等地质灾害迹象。随着两矿剥采工程发展及对相邻端帮进行靠帮作业，相邻端帮到界边坡间将产生一个更为高陡的不规则台体，为避免灾害性滑坡发生，对该高陡台体稳定性分析基础上，提出“整体挖除回填”的治理方式并确定具体的治理方案。该治理方案明确“整体挖除回填”治理方式作业范围，设计了治理完成时清理工作帮及内排土场边坡形态，可彻底消除地质灾害隐患，并释放西二露天矿内排空间931.83万m³，锗煤露天矿内排空间764.69万m³，两矿可继续实现完全内排。本研究成果为西二、锗煤露天矿相邻端帮断层带地质灾害隐患体治理提供必要的理论依据和技术支撑，同时为类似同一煤田相邻露天矿实施地质灾害治理提供了相关经验。

In the development of large-scale open-pit coal fields in China, there are often several Coal companies entering the same coal field, and each Coal company is a main body of development, mining coal resources in the state-allocated strip area, and building several open-pit mines at the same time or successively. Adjacent open-pit mines, during the excavation process, are susceptible to landslide hazards, particularly on the slopes where the adjacent end gangs, influenced significantly by the mining activities of both mines, reach the boundary. The Shengli West 2 open-pit coal mine and Wulantuga Zhemei open-pit mine are neighbouring surface mines in the same coal field, and the mining rights of the two mines do not overlap at the neighbouring end gangs, resulting in the formation of a trapezoidal platform between the west gang of the West 2 open-pit mine and the east gang of the Zhemei open-pit mine, and the impact of the overlying fault fragmentation zones and the operations of the two mines, which resulted in the appearance of signs of geologic hazards within the platforms, such as bottom drums, fissures, and collapse of faults. With the development of the stripping project of the two mines and the leaning operation of the adjacent end gangs, a steeper irregular platform will be generated between the adjacent end gangs and the boundary slopes, in order to avoid the occurrence of catastrophic landslides, and on the basis of the stability analysis of the steep platform, the treatment method of "digging out and backfilling as a whole" was put forward and the specific treatment plan was determined. The management plan specifies the scope of operation of the "overall excavation and backfilling" management method, and designs the shape of the clean-up work gang and the slope of the internal discharge site when the management is completed, which can completely eliminate the hidden geological hazards and release 9,318,300 m³ of internal discharge space in the West Second Open Pit Mine and 7,646,900 m³ of internal discharge space in the Zhemei open-pit mine Mine, so that the two mines can continue to achieve complete internal drainage. The results of this research provide the necessary theoretical basis and technical support for the treatment of geological hazard hidden bodies in the adjacent fault zones of the West 2 and Zhemei open-pit mines, and also provide relevant experience for the implementation of geological hazard management in similar adjacent open-pit mines in the same coal field.
