摘要
西藏谢通门雄村铜矿属于与晚侏罗世侵位的角闪石英闪长玢岩有关的低品位斑岩型Cu(Au)矿床,采用露天开采方案。该矿地质条件复杂,第四系地表覆盖堆集层、冰冻、断层、地下涌水相对突出为显著特征,对包括边坡的稳定性、主运输系统的畅通、安全生产带来严重的影响。通过逐项的分析,分析影响的表现形式。提出了清理第四系地表覆盖堆集层、构建全过程监护系统、优化采场主要参数局部、局部改造主运输道路畅通、建立高效率的防排水系统、加强特殊地质条件下的操作工艺管理、持续开展矿区岩石力学综合研究等综合应对措施。
Xietongmenxiongcun copper in Tibet belongs to a low-grade porphyry Cu(Au)deposit which related to the late Jurassic emplaced hornblende diorite porphyry,and uses open-pit mining.The geological conditions of the mine are complex,and the Quaternary surface overlay,freezing,faults,and relatively prominent underground water gushing are notable features,which have a serious impact on the stability of the slope,the smooth flow of the main transportation system,and the safety of production.Through item-by-item analysis,analyze the manifestation of the impact.It is proposed to clean up the quaternary surface cover accumulation layer,construct a whole-process monitoring system,optimize part of the main parameters of the stope,partially transform the main transportation road,establish a high-efficiency waterproof and drainage system,strengthen the management of the operation process under special geological conditions,and continue to carry out comprehensive measures,among other comprehensive researches on rock mechanics in mining areas.
