RESEARCH ON STABILITY OF RECONSTRUCTED UNDERGROUND ARTIFICIAL STRUCTURE IN MINING ENVIRONMENT BY COMPREHENSIVE METHOD AND ITS APPLICATION

The stability research on underground space project such as mining is always a popular issue in geotechnical engineering.Based on the analysis and summary of the research achievement of underground structure stability at home and abroad in recent years,an organic combination of the mathematical analysis method,experience analogy method,similar model test method,a numerical simulation method and field monitoring method is tried;a comprehensive analysis method for researching on underground artificial structure stability is put forward.The comprehensive analysis method is applied to engineering practice;and realization of feasibility of mining safety and high-efficiency stoping through the mining environment under the condition of loose and fractured ore rock is discussed.The research result shows that this comprehensive evaluation method is feasible and practical,so as to provide scientific reference for such complicated problems.
