摘要:
PURPOSE: A method for blasting a tunnel using horizontally laminated blast layers is provided to effectively prevent noise, vibration, and the scattering of rocks caused by blasting upper rocks from being delivered to the upper part of as blasting is started from the bottom of tunnel. CONSTITUTION: A method for blasting a tunnel using horizontally laminated blast layers is as follows. Multiple first blasting holes are horizontally formed in the lower part of the tunnel to form a blasting hole layer(S100). Multiple second blasting holes are formed above the blasting hole layer(S200). After blasting the first blasting holes, the second blasting holes are blasted(S300). [Reference numerals] (S100) First blasting hole forming step for forming multiple first blasting holes in a horizontal direction in the lower part of a tunnel; (S200) Second blasting hole forming step for multiple second blasting holes sequentially in a horizontal direction above the first blasting holes; (S300) Blasting step for blasting the first blasting holes and then blasting the second blasting holes sequentially from the bottom
