5.2.4 drill blasting

Because the slope of the inclined shaft is too large, the wheel type rock drilling trolley cannot be used for drilling. The manual drilling operation adopted in the inclined shaft is very easily limited by the operation environment, the operation area at the working face of the inclined shaft is small, the drilling direction is not easy to control, and the overbreak is easily caused. In contrast, after careful investigation, the project part provides a 'person-fixed positioning' mode, namely, the drilling operation personnel are fixed to operate at the fixed position of the inclined shaft, and effective control over the overbreak and the expanded excavation body type is realized.

Because of the slope of inclined shaft is big, normal walking in the inclined shaft can no longer be had to ordinary wheeled excavation platform truck, for guaranteeing engineering progress and construction quality, item portion has welded the excavation rack on the basis of PC160 excavator chassis, sets up hollow cylinder in the different positions of excavation rack, and the reinforcing bar of being convenient for passes, then lays steel bar grating on the reinforcing bar to it is fixed firm to use the steel wire, forms the repacking excavation platform truck that is applicable to the inclined shaft more.

And the influence of the large-gradient inclined shaft on the excavation drilling is overcome by adopting electric drive, and the construction environment in the inclined shaft is also ensured. When the modified excavation trolley reaches a designated position in front of a tunnel face, a construction steel bar grating is set up, and a drilling team holds the air leg rock drill to perform manual drilling. The rock drill hand adopts the safety belt to suspend the operation, avoids the sudden short rod to cause the casualty accident. The direction of the blast hole is checked by an angle measurer, the directions of the cutting hole and the peripheral holes are strictly controlled, the slope angle of the formed well after blasting is consistent with the design, and simultaneously, the middle waist line must be aligned before each drilling. In order to avoid the blockage of the blast hole, after one blast hole is drilled, a marker is blocked at the hole opening, so that the smooth completion of blasting is facilitated.

The charging and networking mode of inclined shaft construction is basically the same as that of other tunnel face construction, and the difference lies in the detonation mode, and because of the influence of stray current, in order to ensure safety, the antistatic electric detonator is adopted for detonation, and the water-resistant emulsion explosive is subjected to smooth blasting.
