Abstract In recent years, due to unclear mining technical conditions and improper exploitation, shaft submergence, mine collapse, geological disaster and environmental pollution happen frequently. The Wandongshan ore block of Beiya gold mine is without exception. With data collection, hydrological-engineering-environmental mapping, project recording, dynamic observation and sample testing, the hydrogeology, engineering geology, environmental geology conditions of Wandongshan ore block are ascertained, which provides basis for mining design and ensures safety in production. It is suggested that all mine enterprises fully recognize the urgency and importance of mining technological condition evaluation, so as to make sure safety production and environmental protection, and achieve good economic, social and environmental benefit at the same time.
