| Abstract: | Based on analyzing the hole sealing characteristics in
“three soft” seam, appropriate hole sealing method is selected. The hole sealing
technique of Bimlarl hole sealing device is experimented. Problems in is application are
discussed. A kind of one-way valve matching the device is designed, by which the hole
sealing through injecting water into “three soft” coal seam is succeeded. This
technique is also feasible to be used in coal seam under similar condition. |
