Description

Technical Field

[0001] The utility model relates to an inclined drilling auxiliary device, in particular to an inclined drilling hole opening azimuth positioning device. Background Art

[0002] The blast holes for open-pit mine chute descending blasting and fixed step pre-splitting blasting are usually 65 0 ~75 0 The positioning parameters of inclined blastholes include inclination, azimuth and hole depth. The control accuracy of the design positioning parameters in the actual perforation process directly affects the stability of the lower step chute and the fixed step slope. The control of the blasting effect is crucial to the production organization and safety management of open-pit mines. Good control of blasting effects is inseparable from accurate drilling parameters (inclination, azimuth, hole depth). Although the drilling rig used has the function of adjusting the drill rod inclination and measuring the hole depth, the hole opening azimuth cannot be given by itself, and manual orientation is required.

[0003] At present, before controlled blasting drilling and perforation in open-pit mines, the drill bit is placed at the hole mouth, and the azimuth of the drill rod is measured by a geological compass to determine the azimuth of the hole. During the operation, two people are required to cooperate, one to operate the compass, and the other to adjust the position of the drill rig at the same time. The process is complicated and the work efficiency is low. In addition, the high-voltage wires, iron tools and vibrations of the drilling rig engine at the operation site reduce the accuracy of the compass measurement, resulting in low accuracy in the azimuth of the drilling hole, which seriously affects the effect of controlled blasting. Therefore, it is particularly important to invent a device that can simply, quickly and accurately determine the azimuth of the drilling hole. Utility Model Content
