Description

Technical Field

[0001] The utility model relates to the technical field of tunnel construction, in particular to a slotting eye auxiliary positioning tool and a rock drilling trolley. Background Art

[0002] Smooth blasting is a controlled blasting technology that keeps the new wall surface flat without obvious damage. Its characteristics are to drill a row of smooth blasting holes on the designed excavation contour line with a hole spacing matching the minimum resistance line, and use uncoupled charges or other special charge structures. After the main excavation is blasted, the charges in the smooth blasting holes are detonated at the same time, thus forming a smooth and flat excavation surface that runs through the smooth blasting holes.

[0003] In addition to being used in open-pit excavation, smooth blasting technology has also achieved good results in the construction of many underground projects in my country (such as mine development tunnels, underground factories, hydroelectric power stations, oil depots, tunnels, national defense structures and other permanent buildings). In particular, when building some hydraulic tunnels, it can not only reduce the situation of over-excavation and under-blasting, but also reduce the hydraulic friction coefficient to the level of a smooth surface that can only be achieved with special linings. It can be seen that smooth blasting is a new blasting technology that rationally utilizes the energy of explosives.

[0004] The basic principle of smooth blasting is to control the blasting effect of explosives, convert more of the violent work into the explosive force work, reduce the initial impulse of the explosive explosion, thereby reducing the damage to the rock mass of the blast hole wall, and control the blasting cracks to develop in the expected direction. It is usually achieved by reasonably selecting explosives and charging structures according to different rock formations, correctly selecting the blasting parameters of the surrounding holes (i.e., hole spacing, resistance line, charge amount), and ensuring that the surrounding holes are detonated simultaneously.

[0005] When performing smooth blasting, it is necessary to drill slots on the face to be blasted. In the prior art, when drilling slots, it is impossible to accurately determine the excavation angle of the slots to be drilled, which easily leads to the risk of secondary explosion between adjacent slots.
