三山岛金矿深井充填系统影响因素分析及优化

随着当前近地表矿床资源的日益枯竭，矿山开采正在向深部迈进，但由于深部岩石应力不均衡，容易产生冲击地压，并受到温度和湿度快速上升等因素的影响，深井作业环境及空气质量更加恶劣，直接造成作业人员工作效率降低，回采成本升高。基于此，针对三山岛金矿深部回采过程中产生的充填工艺问题进行研究，解决充填倍线变化、充填满流度变化、浆料颗粒及流速对管道内壁的作用等严重影响充填质量的技术性难题，更好地维护深井充填系统稳定。

Influence Factors Analysis and Optimization of the Deep Well Filling System at Sanshandao Gold Mine

With the near-surface deposit resource increasingly drying up,mining is towards deep.Meanwhile, because the deep rock stress is imbalance,it seems easy to impact ground pressure.Additionally,the deep rock is under the influence of factors, such as temperature and humidity rising fast,working environment and air quality would be worse,therefore,which can directly cause the less efficiency work,and higher recovery costs .Thus,the filling process problems in the process of deep recycle at Sanshandao gold mine is studied in order to solve the problems of filling times line changes,filling full mobility,slurry particles and the velocity which acting on inner wall of pipeline and caused seriously affects to the quality of filling technical, that is of great importance for keeping the deep filling system stable.
