Research on Optimization of Key Areas of Drainage Borehole Sealing in Ultrathick Coal Seam

Gas drainage is an important means of gas control. The influence of the key position of the sealing hole on gas drainage was studied by theoretical and numerical simulation combined with field measurement to solve low gas concentration in gas predrainage boreholes in coal mines of China. By analyzin...
