Abstract: A separated composite excavation method in pre-large hole boring method (PLHBM) is provided. According to the separated composite excavation method in PLHBM, a tunnel excavation section for a front surface or an upper half surface, in which pre-large boring is used depending on the properties of rock around a tunnel, is divided into a primary lower zone and a secondary upper zone by the need to reduce vibration and then the optimum excavation method is determined. The destruction direction of an excavation destruction hole in a secondary upper excavation surface faces downwards for better working conditions. The center of an excavation surface of the primary lower zone, which makes first and second excavation boundary surfaces bulge upwards to reduce the risk of rockfalls during excavation of the secondary upper zone after excavation of the primary lower zone, has a height of 1.6m from the bottom to a large-sized first hole to reduce work and the outermost holes thereof on left and right sides have a height of 0.4 to 1.2m, keeping it as small as possible from the bottom. According to the method of the present invention, a pentagonal shape generated in one pre-boring large-sized hole or a hexagonal shape generated in two or more pre-boring large-sized holes is the smallest excavation cross-section. The one pre-boring large-sized hole is bored first. In case of two or more holes, while the distance from the center of one large-sized hole to the center of a neighboring large-sized hole is 0.8 to 1.3m, in the primary lower zone having the smallest cross-section of pentagonal or hexagonal shape, special controlled blasting for large-sized holes is performed with the minimum amount of charge resulting from decreases in the burden and spacing. In the secondary upper zone, the rock is excavated by mechanical excavation equipment through mechanically-excavated auxiliary holes in various sizes created after pre-boring.
