全苏有色金属矿冶科学研究所和赫鲁斯塔里涅斯基采选公司合作,试验和使用了井下回采坚硬矿石的连续回采工艺。该工艺是以深孔落矿、用全苏有色金属矿冶科学研究所设计的КВВ-2和КВВ-3型配套振动机械放矿为基础。在中央矿7号矿体的几个矿块已用连续工艺采完。矿体上部贫矿带厚达60米,下部“矿化带”的厚度变化在2～15米之间。矿体倾角从45°到90°。矿体边界根据巷道中的地质取样资料、钻探岩心和深孔凿岩时的岩粉来确定。矿石是非常致密的、中粒结构的石英砂岩,中间夹有许多无规律的薄(1～3厘米)石英脉,
All-Soviet non-ferrous metal mining and Metallurgical Institute of Science and Juru Stalilienski mining company cooperation, testing and the use of underground mining hard ore continuous recovery process. The process is based on the deep hole mining, with КВВ-2 and КВВ-3 supporting vibratory machinery drafting designed by the Institute of Mining and Metallurgical Science and Technology of All-China Nonferrous Metals. Several ore blocks at No. 7 ore body at Central Mine have been mined by a continuous process. The ore-bearing upper lean zone is up to 60 meters in thickness, and the thickness of the lower “mineralized zone” varies from 2 to 15 meters. Ore dip angle from 45 ° to 90 °. The ore body boundary is determined according to geological sampling data in the roadway, drilling core and rock dust during deep hole drilling. Ore is a very dense, medium-grained quartz sandstone with many irregular (1-3 cm) quartz veins sandwiched in between,
