| Abstract: | The technology of different micro- differential deep inclined channel blasting can enlarge the depth and volume of cutting. To extract rapidly, the big diameter explosive is used for cutting hole, but little diameter explosive is used for peripheral hole. Series-parallel network one-time blasting is used at full section so that the roadway formed well is good for roadway support. |
