Description
Technical field
The present invention relates to a kind of detection burst region solution cavity, weak intercalated layer, tomography and crushed zone and enter according to structural feature
The method of row explosion design.
Background technology
The geological structure that solution cavity, weak intercalated layer, tomography and crushed zone Shi Bao district are relatively conventional, the existence of special geological structure
The safety of blast working is had a huge impact；Wherein, the existence of solution cavity forms coyote hole and produces and fly when easily causing powder charge
The existence of stone, weak intercalated layer and crushed zone can change burden direction, makes blasting energy waste, it is also possible to bring surrounding
Safety threaten, the existence of tomography makes explosion energy waste, and demolition effect is poor；After making explosion, lumpiness is relatively big, produces two
Secondary broken, can not predict under complex environment that solution cavity feature can only use other crumbling methods to carry out process and cost is increased,
Slow down progress.Meanwhile, sweeping solution cavity is it may also happen that subside so that blast working danger coefficient increases.This is a series of
The safety of factor serious threat surrounding, therefore, look-ahead quick-fried district solution cavity, weak intercalated layer, tomography and the existence of crushed zone
And carry out the design of territory, karst region Hole pattern parameters and be necessary.
During blast working, owing to being difficult to grasp the feature of special geological structure, there is a lot of uncontrollable risk factor and
Reduce the safety coefficient of blast working, all do not detect quick-fried district geological conditions before the blasting design scheme establishment of present stage, cause
Cause when practice of construction blasting design scheme to be difficult to guidance technology personnel to construct, reduce the safety system of blast working
Number.
Summary of the invention
In order to solve the problems referred to above, the present invention provides a kind of radar detection geological conditions and carries out the side of explosion design
Method, can grasp architectonic feature by detection, it is to avoid carry out what blast working brought under special geological tectonic conditions
A series of risk factors, improve the practicality of explosion design, improve the safety during blast working, reduce construction cost.
The method comprises the steps:
1) remove quick-fried district top layer vegetation, utilize tape measure or tape measure to carry out arrangement of measuring-line along the row or column direction in big gun hole, quick-fried district, and do
Go out labelling；
2) geologic radar detection parameter is set；By geological radar launch and reception antenna according to set detecting parameter along survey line
Direction detects, and geological radar will launch frequency electromagnetic waves by launching antenna, and frequency electromagnetic waves runs in communication process
Different structure face, such as solution cavity, weak intercalated layer, tomography and crushed zone, will make echo strengthen, and receive signal by receptor and remember
Record reflection of electromagnetic wave image；
3) analyzing and processing reflection of electromagnetic wave image, learns the size of solution cavity, weak intercalated layer, tomography and crushed zone, shape and the degree of depth,
According to analysis result, big gun hole site, hole depth and the pitch-row in quick-fried district is designed.
In described method, described arrangement of measuring-line mode is chosen:
Determine row and column direction, big gun hole according to quick-fried district surrounding and topography and geomorphology, survey according to the row in big gun hole or the position of row
Line is arranged.
In described method, the choosing of geological radar antenna combines the investigation depth of explosion design hole depth and different antennae and carries out
Determine.
Use said method, the architectonic features such as solution cavity, weak intercalated layer, tomography and crushed zone can be detected, arrange
Rationally Hole pattern parameters, can be effectively improved construction speed, reduces cost, improves blast working safety coefficient.

Detailed description of the invention
It is easier to make the present invention have understand, illustrates below in conjunction with accompanying drawing.
It is illustrated in figure 1 and utilizes the architectonic feature in below the quick-fried district of geologic radar detection and carry out the equipment of explosion design
Arrange and detection schematic diagram.
It is illustrated in figure 1 geologic radar detection solution cavity the method carrying out explosion design of utilizing of the present invention, wherein
Comprise the following steps:
Remove quick-fried district top layer vegetation,
According to quick-fried district feature and surrounding requirement, determine the row and column direction in big gun hole；
The row or column selecting big gun hole is line direction, and every row or column is a survey line, utilizes tape measure to carry out geologic radar detection survey
The labelling of beginning and end is arranged and done to line；
Geologic radar detection parameter is set；
According to geological radar arrange detecting parameter, carry out detecting and doing data acquisition along line direction, obtain every survey line with
The lower geological structure reflectance data to electromagnetic wave；
Launch antenna and launch high-frequency impulse ripple, when high-frequency impulse ripple runs into solution cavity, due to structural plane both sides difference in dielectric constant
Greatly, reflex strength strengthens, and the impulse wave of transmitting is received by reception antenna and record, according to transmitting and the reception of high-frequency impulse ripple
Time time difference and spread speed in rock, the position of rock structural face can be calculated；
By the data of reflective information and the image of preservation are processed and analyze, according to the reflection of the structural plane of wall scroll survey line
The measurable Geologic Structure Feature of information, it is known that every the survey line geological structure degree of depth, length and width.
Fig. 2 is to launch antenna and reception antenna layout schematic diagram in the present invention.
Launching antenna in Fig. 2 and reception antenna is arranged on survey line, such as survey line 1 in figure, distance between the two is according to setting
Set a distance is fixed, and when starting to detect makes marks starting point, FRPA-Fixed Radiation Pattern Antenna and the distance of reception antenna, does number when starting to measure
According to collection.Every survey line all repeats above step when measuring, until all of survey line has detected, obtains every following rock of survey line
Reflective information, then complete detection.
When Fig. 3 is detection, the schematic diagram of electromagnetic wave generation strong reflection is caused on reflection solution cavity surface, and vertical coordinate represents the degree of depth, horizontal
Each measuring point of coordinate representation and the distance of initial measuring point；
By analyzing, with the presence of solution cavity below the earth's surface of this survey line, there is each survey of degree of depth deducibility of strong reflection according to it
The degree of depth of the following solution cavity of point.
Fig. 4 is the schematic diagram that special tectonic face makes electromagnetic wave generation strong reflection；
By analyzing, below the earth's surface corresponding to this survey line, there is special structure face, special in the face of the reflection of electromagnetic wave according to structure
Levying deducibility is layer reason or weak intercalated layer or crushed zone；
Comprehensive above result of detection, is analyzed the geological conditions below every survey line, it was predicted that the geological structure in quick-fried district, and root
According to structural feature, hole array pitch and the position in big gun hole are reasonably designed.
