分段空场法在破碎薄矿脉中的试验研究

Test of Sublevel Open Stoping on Narrow Fractured Ore Vein

根据辽宁五龙金矿76号脉矿岩破碎，断层节理发育．开采技术条件复杂的特点，成功地应用了综合护顶技术，首次在国内急倾斜破碎薄矿脉中试验成功了分段空场法．阐述了该试验方案的结构，采矿工艺特点，回采工艺特证，采取的技术措施及取得的主要技术经济指标．本项科研成果的取得为该类黄金矿术开采创出一条新路．

Based on the complex mining conditions and the developed fracture, faults and joints in the wall rock of No. 76 vein in Wulong Gold Mine, the comprehensive roof support method is successfully applied. The sublevel open stoping method in pitching narrow fractured vein is successfully tested in China. The structure of the test plan, the technological characters of mining and stoping, the technical measures taken and the main indices of technology and economics are discussed. The achievements of the research open a new way to the mining of this type of gold deposit
