Abstract
The utility model discloses a combined slot exploding cutting groove drilling tool of drill-hole wall for sinking and driving, which is an exploding drilling tool of excavating engineering and comprises an axial cutting groove drill bit of the drill-hole wall and a radial cutting groove drilling tool of the drill-hole wall. The function is to make cracks in advance along the axial direction and the radial direction, and after exploding, and the surrounding rock on the periphery of the sinking and drifting is made flat and smooth. The exploding efficiency achieves above 98%; compared with the traditional exploding method, the work amount of rock drilling is reduced by 20%, and the charge quantity is decreased by about 30%.
Description
The utility model belongs to the mining operation explosive drilling tool.
The digging industry still mainly adopts in the excavation explosion and arrange easer, breaking hole, perimeter hole on work plane both at home and abroad at present, then the traditional handicraft of charge explosion.The shortcoming of this method is that blasting efficiency is low, and it is big to the destruction of roadway peripheral rock to explode, and explosive and other raw materials consumption amount are many, and the interior blasting fume dust of well volume is many after the explosion, and condition of labor is poor.Improve blasting efficiency, the integrality of protection roadway peripheral rock is one of major subjects of the unremitting discussion of digging industry.
The appearance of smooth blasting and slotted eye blasting technique and application are tentatively solved the integrality of roadway peripheral rock, still the blasting efficiency that exists in traditional blasting method are hanged down and wait other shortcomings still to fail to overcome.
The characteristics of slotted eye blasting technique are that on the big gun hole wall that Drilling is good, periphery cuts two grooves symmetrically vertically; precrack on the big gun hole wall artificially; formation stress is concentrated, and rock reaches the purpose of protection roadway peripheral rock along the predetermined direction rupture failure when being beneficial to explosion.The grooving method mainly contains two kinds of high-pressure water jet grooving and machine tool groovings.A kind of drilling tool that is used for crisp such as directed cracking stone material is introduced in application for a patent for invention numbers 86108665, form by drilling rod, cutter head and locator card, cutter head upper side symmetric arrangement has two cutters, and a side powder outlet arranged, can carve the stress groove at stone hole inwall, can make the stone material cutting neat, make things convenient for the exploitation of stone material greatly.But this grooving drilling tool complex manufacturing technology, the grooving number is limited.
Improving raw-material consumption such as blasting efficiency, minimizing rock drilling workload, reduction explosive, guarantee roadway periphery integrated degree, improve working conditions, is the purpose of this utility model.
Carrying out the explosion of combination slotted eye roadway can achieve the above object.The master operation of combination slotted eye roadway explosion is: hole (eye) arrangement diagram of pressing design is in sinking and drifting face Drilling big gun hole (eye), secondly cut axial groove at the big gun hole wall by designing requirement, cut the circumferential annular groove in big gun hole wall bottom then, its purpose is prefabricated one group of crackle on the foot of hole plane of multiple operation face, thereby reach the purpose that improves blasting efficiency, powder charge in the big gun hole at last, plug-hole, water filling, detonate.
The utility model provides a cover to be applicable to the drill hole wall grooving drilling tool of combination slotted eye roadway explosion.Cut axial groove at drill hole wall and use the axial grooving drill bit of drill hole wall, cut the circumferential annular groove in the drill hole wall bottom and use drill hole wall radial cut traverse drill tool.
