Description

Rapid hole depth data detection device and method thereof Technical Field The invention relates to the technical field of hole depth detection, in particular to a device and a method for rapidly detecting hole depth data. Background In the excavation of tunnels and the construction of other civil engineering, the drilling and blasting method has strong adaptability to geological conditions and low excavation cost, so the drilling and blasting method is a current tunnel excavation method commonly used at home and abroad. The parameters such as depth, angle, interval and aperture of the blast holes during drilling and blasting are critical to blasting excavation effect. The blast hole parameters have great influence on the loading capacity, the ore bulk rate, the ore powder rate, the super-undermining, the circulating footage and the like, and further have great influence on the engineering cost, the engineering progress and the engineering quality. Thus, the parameters of the blasthole need to be measured before blasting. The inventor finds that at present, the existing measuring mode is mainly tape measure, the measuring efficiency is low, the measuring data is not accurate enough, and blast hole parameters at unfavorable positions of space positions are difficult to measure manually, so that blasting effect is influenced, surrounding rock damage and serious super-undermining are caused, tunnel construction speed is seriously influenced, and engineering cost is greatly increased.
