以鸡笼山金矿低品位斑岩型16号矿体361矿块的回采为实例,简要地介绍了分段浅孔留矿嗣后充填采矿法在缓倾斜中厚矿体开采中的优化和应用.生产实践表明,对顶底板围岩稳固、缓倾斜中厚矿体,采用分段电耙道漏斗受矿、溜井出矿的分段浅孔留矿嗣后充填采矿法是比较合适的,可供同类型矿体回采参考.
The paper takes the extraction of Ore Block 361 in the low grade porphyry Orebody 16 in Jilongshan Gold Mine as the research subject, briefly introduces the application and optimization of subsection shallow hole shrinkage and subsequent filling in the extraction of moderately dipping medium-thick orebodies.Production practice shows subsection shallow hole shrinkage and subsequent filling,which applies subsection electric rake chute for feed-ing and ore pass for discharge,is fit for moderately dipping medium-thick orebodies with stable roofs and floors.The method can be referred to by similar orebodies.
