, Inner Mongolia Chagan Tailings Backfill Mining Methods To Approach Experimental Research, Silvermine 3 # Ore Body

With the increase of mining depth and the change of mining conditions as well as the development of modern scientific technology and mining equipments, filling mining has gradually become one of safe, economical and efficient methods<, However, it is very important to choose the mining method in light of idiographic mining tethnology conditions of certain ore deposit ?This paper has studied the No.3 mineral deposit of Chagan Sivel Mine, and given a preference to up-towards cemented filling a Based on indoor experiment and filling experience of similar mine, the mine has finished the industry experiment and a study on drilling-and-blastingm, filling material, filling system, filling roof joint, the stability of fillbody, stope dynamic, and so on0 The condusions are as follows:The tailings cemented filling is completely correct, and its social effect and economic benefits are obvious; ?The interface blasting technique in different medium is used successfully; (? A series of techniques, such as the compelling filling roof joint, the construction methods of subarea mining and subarea reinforce filling , area filling roof joint after mining and so on, are all in the highest flight in domestic correlation fields; ?The dehydration effect is good when the mosquito-net cloth is used as dehy-drated material; (5) The distributing range is made clear based on the analysis methods of stress finite element oThe experiment research result shows that the mining method of up-towards tailings cemented filling at Chagan Silver Mine is successful, Thus it is of deploymental value to mine for other mineral deposit.
