Description
Invention Title: BLAST DESIGN SYSTEM FOR REFLECTING BLAST
Technical Field
[1] An exemplary embodiment of the present disclosure relates
to a blast design system for reflecting a blast site situation,
and an operation method therefor and, more particularly, to a
blast design system for reflecting a blast site situation, and
an operation method therefor, wherein blasting is designed by
reflecting the blast site situation at each stage, and a
blasting design may be revised and analyzed on the basis of a
work result at each stage.
Background Art
[2] In general, a blasting system, which blasts and
demolishes a target object by using an explosive, is used in
the field of construction where blasting of bedrock, blasting
of abandoned buildings, blasting in open-pit mines, and the
like are conducted.
[3] Specifically, an area or target object, which is to be
blasted, is divided into a plurality of sections, and a
plurality of blast holes into which explosives are inserted is
drilled for each section. After the explosives are inserted into the respective drilled blast holes, the blast holes are connected to a blasting device. By detonating detonators positioned in the blast holes, the explosives are exploded and the blasting target object is blasted and demolished.
[4] Regarding the operation of such a blasting system,
conventionally, each process is directly performed by a human,
or is performed by a machine operated by a human. However,
there is a possibility that human errors may occur in such a
conventional blasting system. In addition, there is a problem
that a blasting result of the blasting system does not satisfy
required conditions (e.g., a degree, a scale, fragmentation,
vibration, noise, and the like of blasting) due to the errors.
[5] In addition, a conventional blast design system proceeded
with blasting design on a virtual plane. However, since the
blast design system, which performs the blasting design on the
virtual plane, is unable to reflect three-dimensional actual
terrain information, there is a problem that reliability of
result prediction is greatly reduced.
[6] In addition, work such as drilling and charging may cause
differences between the blasting design and an actual work
result, and the differences are rather large compared to
expectations. Since the conventional blast design system
predicts a blasting result on the premise that each task
proceeds correctly in accordance with the blasting design,
there is a problem that the actual blasting result may not be reflected. Accordingly, in the conventional blast design system, when comparison of the blasting result is performed by using blasting prediction data and result data, there is a problem that meaningful result values may not be derived.

wherein a three-dimensional (3D) terrain model for a blasting

[55]
[56] FIG. 1 is a view illustrating a blast design system 10
according to the exemplary embodiment of the present
disclosure.
[57] Referring to FIG. 1, after generating a 3D terrain model
from a point cloud obtained by using a drone and LiDAR and
proceeding with blasting design based on the 3D terrain model,
the blast design system 10 may transmit a blasting design to a
drilling device, a charging device, and detonation devices.
The drilling device, the charging device, and the detonation
devices may proceed with each step of the blasting work in
accordance with the blasting design, and transmit result data
back to the blast design system 10 as each step is completed.
In addition, the blast design system 10 may optimize the

of the result data. In addition, the blast design system 10 may predict a blasting result on the basis of the blasting design, perform an analysis by comparing the predicted blasting result with an actual result, and adjust parameters by reflecting an analysis result to the parameters used in a model for prediction. Through this way, the blast design system 10 may predict the blasting result more accurately.

line and a toe line of a bench by generating multiple points
of a point cloud, specify an area corresponding to the crest
line and toe line, and specify an area between the crest line
and the toe line as a free face.
[66] According to the exemplary embodiment, the model creation
unit 200 may create a 3D terrain model that smoothly mimic
real terrain by using Poisson-Delaunay triangulation.
[67] The blasting design unit 300 may create a blasting design

present specification, the blasting design may include: three
dimensional terrain information including location information

[68] To this end, the blasting design unit 300 may include a
drilling design unit 310, a charging design unit 320, and a
firing time design unit 330.
[69] The drilling design unit 310 may create a drilling design
by designing a plurality of blast holes in a 3D terrain model.
The drilling design may include data on position information,
a tilt, a direction, a shape, and the like for each of the
blast holes.
[70] The charging design unit 320 may create a charging design
by designing charging for the plurality of blast holes. The
charging design may include data on the types of explosives
charged into the blast holes, the types of detonation devices,
specific gravity, energy, and the like.
[71] The firing time design unit 330 may create a firing time
design by designing times in milliseconds for the plurality of
detonation devices loaded into the plurality of blast holes.
In the present specification, the times in milliseconds may be
referred to as firing times.

unit 410 may calculate a volume prediction value of a
structure demolished through blasting work.

[106]Hereinafter, the operation method of the blast design

[107]
[108]
[109]FIG. 3 is a flowchart illustrating in detail the
operation method of the blast design system 10 according to
the exemplary embodiment of the present disclosure. FIG. 4 is
a view illustrating in detail the operation method of the
blast design system according to the exemplary embodiment of

[110]Hereinafter, with reference to FIGS. 1 to 4, step S20 of
creating the 3D terrain model, by the model creation unit 200
of the present disclosure, by using at least one of the drone
and Light Detection And Ranging (LiDAR) will be described in

[111]First, in step S21, the model creation unit 200 may

TL of a bench. As shown in FIG. 4, the model creation unit
200 may create a 3D terrain model measured by the drone or

[112]As shown in FIG. 4(A), in step S22, the model creation
unit 200 may specify an area corresponding to the crest line
CL and the toe line TL. That is, the model creation unit 200
may specify a section corresponding to the crest line and the

[113]As shown in FIG. 4(B), in step S23, the model creation
unit 200 may specify an area between the crest line CL and the
toe line TL as a free face FF. That is, the model creation
unit 200 may specify the free face corresponding to an

way, the model creation unit 200 of the present disclosure may

[114]
[115]FIG. 5 is another flowchart illustrating in detail the
operation method of the blast design system 10 according to
the exemplary embodiment of the present disclosure.
[116]Hereinafter, with reference to FIGS. 1 to 5, step S30 of
creating a blasting design on the basis of the 3D terrain
model by the blasting design unit 300 of the present
disclosure will be described in detail.
[117] In step S31, a drilling design unit 310 may create a
drilling design by designing a plurality of blast holes in the
3D terrain model. The drilling design may include details
about a location and shape of each blast hole of the plurality
of blast holes. For example, the drilling design unit 310 may

arrangement in the 3D terrain model.
[118]A charging design unit 320 may create a charging design
by designing charging for the plurality of blast holes. The

[120]
[121]FIG. 6 is a yet another flowchart illustrating in detail
the operation method of the blast design system 10 according
to the exemplary embodiment of the present disclosure. FIG. 7
is another view illustrating in detail the operation method of
the blast design system 10 according to the exemplary
embodiment of the present disclosure.
[122]Hereinafter, with reference to FIGS. 1 to 7, step S31 of
designing, by the drilling design unit 310 of the present
disclosure, the plurality of blast holes in the 3D terrain
model and creating a drilling design will be described in
detail.
[123]In step S311, the drilling design unit 310 may calculate
burdens and spacings of the plurality of blast holes according
to respective distances between the free face and the
plurality of blast holes designed in a 3D physics engine (e.g.,
the 3D terrain model). For example, the drilling design unit
310 may calculate burdens and spacings with respect to the
free face FF for at least one of the plurality of blast holes.
[124]In step S312, the drilling design unit 310 may adjust
angles and directions of the plurality of blast holes, so that
the respective burdens may be set within a preset range
according to an angle and a direction of the free face FF.
For example, as shown in FIG. 7(A), when burdens (e.g.,
distances, along the depth, from the free face FF) of a
designed blast hole are out of a preset range, the shape (e.g.,
the depth, direction, angle, etc.) of the blast hole may be
redesigned so that the burdens are positioned within the
preset range. That is, when the blast hole BH is designed to
be inclined with respect to the free face FF as shown in FIG.
7(A), the drilling design unit 310 may adjust the burdens, so
that as shown in FIG. 7(B), the blast hole BH is substantially
parallel to the free face FF.
[125]According to the exemplary embodiment, the drilling
design unit 310 may receive input of an ideal burden and
tolerance, and calculate a preset range of a blast hole. The
drilling design unit 310 may utilize the calculated range as a
shape correction guideline of the blast hole.
[126]
[127]
[128]FIG. 8 is a still another flowchart illustrating in
detail the operation method of the blast design system 10
according to the exemplary embodiment of the present
disclosure.
[129]Hereinafter, with reference to FIGS. 1 to 8, step S32 of
creating, by the charging design unit 320 of the present
disclosure, a charging design by designing charging for the
plurality of blast holes will be described in detail.
[130]In step S321, the charging design unit 320 may set a unit
section according to a depth for each of the plurality of
blast holes.
[131]In step S322, the charging design unit 320 may allocate
explosives by unit section. For example, the charging design
unit 320 may set explosive types, specific gravity, and the
like by unit section, and set the number and lengths of
stemming decks. At this time, preparing for a case where a
length of a blasting hole changes, the charging design unit
320 may set a deck whose length may change depending on a
change in the length of the blasting hole.
[132]
[133]FIG. 9 is a still another flowchart illustrating in
detail the operation method of the blast design system 10
according to the exemplary embodiment of the present
disclosure. FIG. 10 is a view illustrating in detail a firing
time setting method of the blast design system according to
the exemplary embodiment of the present disclosure. FIG. 11
is another view illustrating in detail the firing time setting
method of the blast design system according to the exemplary
embodiment of the present disclosure.
[134]Hereinafter, with reference to FIGS. 1 to 11, step S33 of
creating, by the firing time design unit 330 of the present
disclosure, a firing time design by designing respective firing times for a plurality of detonation devices loaded into the plurality of blast holes will be described in detail.
[135]In step S331, the firing time design unit 330 may set a
delay time per meter (or foot) of apparent burden. For
example, a delay time per meter of apparent burden of general
bench blasting has a value ranging from 10 ms/m (for hard rock)
to 30 ms/m (for soft rock). When the delay time is too long,
the delay time causes generating of flying stones, explosion
sounds, and large masses, and when the delay time is too short,
the delay time may cause rocks in a back row to be moved
upwards instead of being moved horizontally. The firing time
design unit 330 according to the exemplary embodiment of the
present disclosure may set the delay time per meter of
apparent burden, so that the above problem does not occur.
[136]In step S332, on the basis of the delay time per meter of
apparent burden, the firing time design unit 330 may design
respective firing times of the detonation devices loaded into
the plurality of blast holes by using a contour method.
[137] According to the exemplary embodiment, as shown in FIG.
, the firing time design unit 330 may set a prime timing
contour. In this case, the firing time design unit 330 also
sets a delay time r per meter of apparent burden corresponding
to the prime timing contour.
[138]The delay time r per meter of apparent burden may have a
negative number when located on the left side with respect to the prime timing contour, and may have a positive number when located on the right side with respect to the prime timing contour. Accordingly, respective firing times (i.e., detonation times) of detonation devices may be divided into the positive and negative numbers centered on the line of prime timing contour.
[139]However, the present disclosure is not limited thereto,
and the delay time r per meter of apparent burden may be
designed in various ways depending on design methods.
[140]The firing time design unit 330 may set the smallest
firing time to 0 (zero) ms, and calculate a firing time of
each blasting hole on the basis of the set firing time.
[141] For example, the firing time design unit 330 may
calculate a firing time by using [Equation 1].
[142] [Equation 1]
[143]FT = CLD * R - MFI, where FT denotes firing time, CLD
denotes distance from prime timing contour, R denotes delay
time per meter of apparent burden, and MF denotes smallest
firing time.
[144]When a prime timing contour is set, the firing time
design unit 330 may use a straight line-shaped or box-shaped
prime timing contour.
[145]As shown in FIG. 11, methods of using the straight line
shaped prime timing contour may be classified as a method of
using one prime timing contour, a method of using two or more prime timing contours whose boundary lines are identical to a bisector of an angle between two straight lines, and a method of using two or more prime timing contours whose boundary lines are not identical to the bisector of the angle between the two straight lines.
[146]According to the exemplary embodiment, the firing time
design unit 330 may evaluate potential blasting performance
through a delay time per meter of apparent burden, and
continuously determine the delay time per meter of apparent
burden through explosions and consistent change, which are
occurred throughout blasting, and reflect the evaluated and
determined results in the design.

disclosure.
[149]Hereinafter, with reference to FIGS. 1 to 12, step S40 of
generating, by the blasting prediction unit 400 of the present
disclosure, blasting prediction data for at least one of
blasting quantity, fragmentation, vibration, and noise by using prediction parameters on the basis of the blasting design will be described in detail.
[150] In step S41, the blasting quantity prediction unit 410
may calculate a blasting quantity prediction value on the
basis of a blasting design. Referring to FIG. 13, the
blasting quantity prediction unit 410 may calculate the
blasting quantity prediction value on the basis of a burden, a
spacing, a depth (i.e., a length), and subdrilling.
[151]According to the exemplary embodiment, the blasting
quantity prediction unit 410 may calculate a blasting quantity
prediction value per one blast hole through [Equation 2].
[152] [Equation 2]
[153] VL = SP * BD * (LN - SB) , where VL denotes blasting
quantity prediction value, SP denotes spacing, BD denotes
burden, LN denotes length, and SB may denote subdrilling.
[154] The blasting quantity prediction unit 410 may calculate
the total blasting quantity prediction value by applying the
above-described method to all of the plurality of blast holes.
[155]The present disclosure is not limited thereto, and
according to the exemplary embodiment, the blasting quantity
prediction unit 410 may calculate a blasting quantity
prediction value by using the entire size of a blasting area.
[156]In step S42, the fragmentation prediction unit 420 may
calculate the fragmentation prediction value on the basis of
the area information and the blasting design. For example, the fragmentation prediction unit 420 may calculate the fragmentation prediction value by calculating a Kuz-Ram model using the blasting design and the previously input area information.
[157]In step S43, the vibration and noise prediction unit 430
may calculate vibration and noise prediction values on the
basis of the blasting design. For example, the vibration and
noise prediction unit 430 may calculate the vibration and
noise prediction values by using a blast vibration equation.
