|
摘要
与尾砂细骨料充填料浆不同,俸磨砂粗骨料充填料浆分层离析显著,导致充填料浆堵管和爆管事故风险高.针对金川俸磨砂粗骨料充填料浆自流充填输送技术,开展高浓度料浆充填工艺与关键技术研究.首先制定了金川矿山俸磨砂高浓度充填料浆自流输送启动与充填作业程序、优化进路充填挡墙结构和充填顺序,保证充填料浆制备质量和待充采场安全与强度要求;然后通过充填料浆脱水工业试验,提出并实施采场充填料浆滤水方案和排水措施,解决了采场料浆脱水与排水技术难题.最后针对俸磨砂粗骨料充填料浆自流输送系统,深入分析了粗骨料和高浓度充填料浆堵管主要影响因素,提出了堵管处理新方法,在此基础上,提出了俸磨砂粗骨料充填料浆堵管防控技术.
Layered and segregation for a filling slurry of rod mill sand coarse aggregate is remarkable,which is different with a filling slurry of fine aggregate of full tailings,so that the stuck pipe and explosion accident risk is bigger.Considering the gravity filling process using rod mill sand coarse aggregate and high concentration in Jinchuan mine,the key technology was researched.First of all,the start with filling pulp packing operation procedure of gravity convey were made,the structure of retaining wall and filling the order were optimized,so that ensure the quality of filling slurry preparation and filling stope's requirements,by industrial test of filling slurry dewatering,a stope filtering scheme and filling pulp drainage measures were put forward and implemented,which solved the difficult problem stope slurry dewatering and drainage technology.Finally,in view of the coarse aggregate gravity system,the main factors of blocking pipe of filling pulp of high concentration were analyzed and the new method of blocking pipe process was put forward.On this basis,the comprehensive technology and measures of preventing tube plugging for coarse aggregate slurry was put forward.
