Abstract

In order to study the injectability of the advanced inhibiting coal seam and the effect of inhibitor injection, taking the 3 upper coal seam in Nantun mine as an example, on the basis of the fact that this coal seam can be injected, the experiment of pressurized water absorption for coal in 9 different solution of inhibitor was carried out. The minimal aperture of pore that allows inhibitor to be injected is deduced according to the pore distribution. The quality of inhibitor that be injected into the coal is calculated. Research shows that the type and concentration of the inhibitor will have an impact on the injection. MgCl2 at a concentration of 25% is easier to injected into the coal. The minimal aperture of pore that allows MgCl2 to be injected is 0.08μm.Per ton of coal can be injected 3.80 kg of MgCl2. MgCl2 at a concentration of 25% should be given a priority to be used to achieve the advanced inhibition of this coal seam.
