Extraction technology of fine vein gold ores.

The article discusses about an effective system development for mining of thin deposits using small-sized self-propelled machines for high efficiency and completeness of mineral extraction. Furthermore, in this research are given the results of development of fine vein lodes by using sublevel system and high-performance, compact self-propelled machines. The developed technological scheme of ore extraction and delivery by self-propelled VSD is recommended to use in mining enterprises which develop vein deposits with varying thickness of ore and a wide range of occurrence angles.
