Assessment of shaft safety and management system of controlling engineering information

Evaluating shaft safety and establishing management system of controlling engineering information are very important,because more than 90 shafts in thick alluvial areas suddenly have shaft well fracturing or breaking problems,as well as there are more than a few hundreds shafts are of similar geological conditions.Taking the shaft controlling in Yanzhou Coal Mining Group as an example,established assessment and management system and related software.The system includes basical information of mine,measurement results and analysis,and functions of empirical and theoretical forecasting and finite element analyzing,which are confirmed very effective for guiding the shaft well control engineering in practice.
