Research on Fault Zone Water Inrush Time-Effective Rules Based on Creep Mechanics Tests

摘要

Water inrush from the fault in the mine is real time and dynamics, and analysis of fault zone water inrush time-effective rules is extremely important for the prevention of mine water inrush. Creep mechanics tests of fault materials shows that physical characteristics of fault damage are characterized by deformation characteristics, structure effect and theological characteristics, and the big difference exist between characteristic and type of the damage based on the instantaneous and long-term effect of different kind of stress, which is time-effective. After the analysis of mining activities and work behavior during laneway excavation in the coal mines, the ideas that we should focus on precursory information and potential passage of water inrush, and achieve the purpose of prevention of mine water inrush by the way of deterring potential channels of water inrush change into direct channels through timely and reasonable support to prevent increasing of the plastic deformation of surrounding and roof rocks.
