Stability Evaluation and Safety Monitoring of Pressure in Yichang Phosphorus Mine

Abstract:

The disasters dynamics and security of phosphate are important problems in Phosphorus ore-deposit mining. So monitoring in unstable, hazardous areas and goaf can effectively focus on the activities of ground pressure. Based on mine-site exploration, engineering test, collection of physical and mechanical parameters for ore, research of geology and mining conditions, the main controlling factors of ground pressure were identified. Combining practical projects, the fuzzy matter-element model of stability evaluation on ground pressure in empty areas was built and analyzed, which showed the good agreement with the evaluation results and measured values. At the same time, based on the stability of underground mining partition, automatic monitoring system of phosphate was constructed, which may provide some useful advices for the safety study of ground pressure in phosphate rock mass.
