THE RELATIONSHIP BETWEEN ROADWAY DISCHARGE AND MINING DEPTH

    Graphical Abstract
    • Abstract
  • The analytical solution of roadway discharge is given,under the condition of rock permeabillty attenuation with mining depth increase.The relationship between roadway recharge and the depth,the relationship between the discharge from various levels and total discharge changed with the mining depth,are water yield of mine analyzed.It is finally tested by the inrush data of Pinhdinshan Coal Mine.
