Abstract:

Alteration mylonite gold deposit, which is steeply dipping and narrow vein together.With middling steady ore and rock is mined in Hetai gold mine, the shore2holl shrinkage is used as the main mining means for several years, also with mining technologies such as dry2filling stoping and small subsection middle2long2holl empty stoping. In recent years, technology of artifical pillar and sirnilar frarne work, st ructure supporting emptied stope make the mining technology more perfect. The progress of mining technique promote the mine production.

Key words: vein gold orebody, mine method, artificial pillar, disposal of emptied stope, technology progress
