According to the mining method tunnel perforation hole size extensible detecting device and using method, the depth, the diameter and the direction of a perforation hole are detected in real time in the process of mining method construction, thus it is guaranteed that the blasting effect of a mining method tunnel meets the design requirement, the differentiation degree is high, and the operability is high.

Description

technical field [0001] The invention belongs to the field of blasting construction, and relates to equipment for detecting the size of a blast hole in a mining tunnel, in particular to a measuring device for the scalability of the blast hole size in a mining tunnel and a method for using it. Background technique [0002] The tunnel structure has become a common civil engineering structure because of its small impact on the ground environment and high space utilization. In the construction process of tunnel engineering, various construction methods such as open cut method, shield method and step method can be used, among which the mine method has become a widely used construction method due to its advantages of wide application range, fast excavation speed and low construction cost. , which also makes the mining method tunnel become the main tunnel form in tunnel engineering in our country. Tunnel construction needs real-time monitoring and data feedback to the design to mee...

Problems solved by technology

[0003] At present, blastholes for mining tunnel construction mainly rely on workers’ drilling experience to form them at one time. Due to the great differences in the geological environment in which tunnels are located, and the geological conditions during the tunnel excavation process are also prone to changes to varying degrees. In addition, the level of mining method construction personnel varies. , so it is difficult to accurately construct blastholes according to the design drawings, and it is also easy to cause the tunnel blasting effect of the mining method to be difficult to meet the requirements

In view of the fact that there is no efficient and convenient blasthole size detection method in China, a mine method tunnel blasthole size detection device is constructed to enable construction personnel to efficiently and quickly obtain the blasthole depth, blasthole diameter and blasthole direction, so that the tunnel blasting can achieve the desired effect. Dynamic construction ideas are fed back to the designer in real time to adjust the blasting plan in time, which can significantly improve the digitalization, visualization and intelligence level of mining tunnel construction
