Abstract: Based on investigation results of failures in -230~-250m three developing entries, boreholes and ore passes in west District, the paper brings to light the main causes of entry failure and borehole failures and the qualitative laws governing the ground pressure activities in stopes. To the above knowledge, a serial of ground control technologies and measures have been taken in-260m level so that better social and economic benefits have been achieved in the mining. The practice has accumulated experiences for mining other districts and even similar deposits.
