[0084] The following is a detailed description of the human body comfort zoning method under the influence of blasting vibration provided by the present invention in conjunction with the accompanying drawings:

[0085] See also Figure 1 The present invention provides a method for zoning human comfort under the influence of blasting vibration, specifically:

[0086] For illustration purposes, see Figure 2Construction diagram. During the implementation of the invention, tunnels are excavated on the left and right lines respectively, with the spacing between the left and right lines being 18m. The tunnel excavation section adopts a typical circular section with a diameter of 7.1m. The left and right line tunnels are blasted in a section about 45m long each, with the right line being constructed first. The vertical height difference between the top of the interval tunnel and the bottom floor of the main building is 42.10m, and the horizontal distance is 74.65m. The closest building to the explosion source is about 36.1m. The blasthole is filled with 2# rock emulsion explosive, the blasthole diameter is 40mm, the drug roller diameter is 32mm, the trenching holes are arranged in a wedge shape, the single hole is charged with 1.3kg, the cutting depth is 1.5m, the horizontal radial of the tunnel excavation is 62 degrees, and the first sensor is selected symmetrically along the central axis at different steps on the surface for monitoring.

[0087] By extensively monitoring the ground vibration velocity on site, fitting the mathematical model with a large amount of data, and then more accurately zoning the human comfort, the hazards of blasting construction can be reduced as much as possible. According to the parameters, the prediction formula of the ground vibration velocity attenuation law is constructed, and then the human comfort is zoned by the vibration velocity.

[0088] The vibration velocity prediction formula is:

[0089]

[0090] in:

[0091] Where V is the peak velocity of the particles; k, α, and β are all unknown parameters; Q is the weight of the explosive for a single blast; R is the distance from the blast source to the node; and H is the height difference between the blast source and the node.

[0092] When solving for unknown parameters, specifically:

[0093] Step S210: Send a first control command, which includes a command to arrange vibration velocity monitoring points according to the blasting point location parameter information. It should be noted that, by way of example, in the present invention, the first sensor group includes 12 monitoring points, and is located at the surface where human comfort zones need to be made. For details, see Figure 2 In this application, monitoring points numbered 1-12 are arranged in the advance tunnel. At the same time, the sensor used in this application is a blasting vibrometer, and blasting vibration monitoring is performed by the blasting vibrometer. It should be noted that an empirical formula that can reflect the propagation law of blasting vibration waves is obtained. At the same time, for skilled technicians, it is not necessary to be restricted to using 12 sensors arranged on the surface. A small number of sensors can also be used to measure multiple groups of blasting data, and the empirical formula can also be fitted.

[0094] S220: Acquire second information, where the second information includes first vibration response information collected by the first sensor group, where the first vibration response information includes a vibration response generated by at least one blast.

[0095] S230, three unknown parameters in the mathematical model are calculated according to the blasting point position parameter and the first vibration response information. That is, the present invention calculates the three unknown parameters in the mathematical model through the first vibration response information.

[0096] Specifically, S230 includes:

[0097] S231. Acquire third information, where the third information includes distance information between each sensor in the first sensor group and the blasting point and the amount of explosive corresponding to the vibration information collected by the first sensor group each time.

[0098] S232. Extract fourth information from the first vibration response information, where the fourth information includes a peak vibration velocity collected by each sensor in the first sensor group.

[0099] S233. Obtain three unknown parameters in the mathematical model through regression calculation based on the third information, the fourth information and the blasting point location parameters.

[0100] S300, based on the mathematical model, the blasting charge, the vibration velocity of each node within the blasting influence area, the elevation difference between the node and the blasting source, and the distance from the blasting source, the human comfort zone is calculated, specifically including:

[0101] S310, obtaining the weight of the blasting explosive; it should be noted that the weight of the blasting explosive mentioned in this step is the weight of the explosive to be used in the blasting.

[0102] S320. Obtain fifth information based on the relationship between the ground surface vibration level and human body comfort, the fifth information including the vibration direction and vibration speed of the ground surface measurement point, the vibration frequency, and the relationship between the vibration direction and human body annoyance level.

[0103] S330. Construct a vibration velocity prediction formula based on unknown parameters.

[0104] That is, the vibration velocity prediction formula constructed in this step is:

[0105]

[0106] Among them, V is the peak velocity of the particles; k and α, β are all unknown parameters; Q is the weight of the explosive for a single blast; R is the distance from the blast source to the node; H is the height difference between the blast source and the node. It should be noted that when applied in engineering, the unknown parameters in this formula should be known constants after fitting the data obtained from field test monitoring.

[0107] S340, calculating the human comfort zone on the ground surface according to the fifth information and the vibration speed prediction formula. That is, in this step, the human comfort zone on the ground surface can be calculated by the vibration direction and vibration speed of the ground surface measuring point, the vibration frequency, and the relationship between the vibration speed frequency and the human annoyance degree.

[0108] It should be noted that the relationship between the human annoyance levels mentioned in this step is obtained through a vibration table test, and the specific content is shown in the table below.

[0109]

[0110] In this method, a vibration table experiment is conducted to study the relationship between ECG changes and human subjective feelings and vibration parameters during the test. The ECG index RMSSD is used to quantify human subjective feelings, and a quantitative evaluation system for human comfort under the influence of blasting vibration is established. Based on extensive surveys and statistical analyses of human subjective feelings based on real engineering examples, the resulting evaluation system is close to the feelings of the affected people and can make accurate judgments on the human comfort zoning under the action of blasting vibration, effectively reducing the hazards of blasting vibration and improving blasting safety.
