Abstract
At present, prediction of mine inflow mostly focuses on aspects of calculated methods and applied conditions, but rarely considering mine inflow to be effected by excavating process and mined domino offect. Withal, the paper bases on water-bursting mechanism of roof and characteristic of mine inflow of exploited mine in shallowly-buried coal seam, taking mine inflow divide into the diversification water and the immobility water two parts, and according to respective characteristics, putting forward matching calculation methods. Meanwhile, the paper analyzed the condition that inflow of exploited working faces interfere with each other, contraposed different hydraulic boundary conditions, and construed the condition that the calculation formula of working face inflow are applied. In practice, the method has well defined consecution, specific classify, better practicability.
