Description

DESCRIPTION

Invention Title: DRILLING DEVICE AND DRILLING MANAGEMENT

SYSTEM COMPRISING SAME

Technical Field

[1] An exemplary embodiment of the present disclosure relates

to a drilling device and a drilling management system

including the same and, more particularly, to a drilling

device and a drilling management system including the same,

wherein data on a drilling process and result thereof is

collected in real time by using sensors installed on the

drilling device at a large-scale blasting site, data

visualization is provided, and bedrock strength is classified,

so that feedback may be provided to an existing blasting

design.

Background Art

[2] Generally, in order to mine metals or minerals, an open

pit blasting system for exploding an area, in which mine

products are buried, by using explosives is used. In order

for performing such open-pit blasting, first, a blast hole for

charging an explosive should be formed by using a drilling

device at a blasting site. In this case, the drilling device forms the hole by using a drill in the ground at the blasting site made of bedrock or the like.

[3] However, in a conventional drilling management system, it

is difficult to perform precise drilling work by way of

detecting a position or an operation of a drilling device and

an exact spot of a drill or providing a guideline on the basis

of the detected results. In addition, since a drilling step

in a blasting system as a whole is configured separately from

a charging step or a blasting step, there is a problem that it

is difficult to provide feedback to subsequent charging and

blasting services. Due to such a problem, the conventional

drilling management system has limitations that the overall

efficiency of the blasting system is unable to be increased.

example, after the drilling device 100 performs a drilling

step according to the initially created blasting design, the

wireless network may refer to a network connected through at

least one of a satellite telecommunication module, a wireless

mobile communication module, a Bluetooth telecommunication

module, a Wi-Fi telecommunication module, and a LoRa

telecommunication module.

[48]

[49] FIG. 2 is a view illustrating the drilling device 100

according to the exemplary embodiment of the present

disclosure.

[50] Referring to FIG. 2, the drilling device 100 may include

a drilling unit 110, a detection unit 120, a control unit 130,

a display unit 140, and a communication unit 150.

[51] The drilling unit 110 may excavate the ground by rotating

a rod by using a feed motor, and as a result, may form a blast

hole. More details related to the drilling unit 110 are

described in FIGS. 3 and 4.

[52] The detection unit 120 is installed in the drilling unit

110, and is configured to generate drilling information by

detecting at least one of a position, a forward direction, a

drilling angle, a drilling depth, drilling coordinates, and drilling pressure of the drilling unit 110. According to the exemplary embodiment, the detection unit 120 may include a plurality of sensors installed on respective parts of the drilling unit 110.

[53] The control unit 130 may calculate bedrock strength on

the basis of the drilling pressure included in the drilling

information.

exemplary embodiment, the communication unit 150 may include

at least one of the satellite telecommunication module, the

wireless mobile communication module, the Bluetooth

telecommunication module, the Wi-Fi telecommunication module,

and the LoRa telecommunication module.

[56]

[57] FIG. 3 is a view illustrating a structure of the drilling

device 100 according to the exemplary embodiment of the

present disclosure.

[58] Hereinafter, the structure of the drilling device 100

will be described with reference to FIGS. 2 and 3.

[59] The drilling unit 110 may excavate the ground by rotating

a rod by using a feed motor, and as a result, form a blast

hole. To this end, the drilling unit 110 may include a feed

motor FM, a rod RD, a rod arm RA, a control unit CR, a rig RG,

and a movement means CT.

[60] The feed motor FM is disposed at one end of the rod RD to

rotate the rod RD in a circumferential direction. In the

present specification, the feed motor FM may refer to a motor

device for rotating a rod.

[61] The rod RD has a forward angle thereof determined by the

rod arm RA, and may be rotated by the feed motor FM to move

toward the ground. For example, the rod RD may be a screw rod

formed with screw wings, having respective pitch intervals

thereof, on an outer surface. When the feed motor FM rotates

the rod RD once, the rod RD may move forward by a pitch

interval. In this case, depending on the type, the rod RD may

have different pitch intervals. The rod RD may refer to an

excavation rod for the drilling unit 110 to excavate the

ground.

[62] The rod arm RA is controlled by the control unit CR, and

may determine a forward angle of the rod RD.

[63] The control unit CR may control and handle the overall

operation of the drilling unit 110. For example, the control

unit CR may move the drilling unit 110 by using a movement

unit CT, determine the forward direction of the rod RD by

driving the rod arm RA, excavate the ground by driving the

feed motor FM to move the rod RD forward, and form a blasting

hole.

[64] The rig RG is a part where a driving system of the

drilling unit 110 is positioned, and may be disposed at the

rear end of the control unit CR.

[65] For example, the rig RG may refer to a part where the

driving system of the drilling unit 110 or a main body device

is positioned.

[66] The movement means CT may move the drilling unit 110

under the control of the control unit CR. For example, the

movement means CT may be implemented through various movement

means such as wheels and caterpillar tracks.

[67]

[68] The detection unit 120 is installed in the drilling unit

110, and may generate drilling information by detecting at

least one of the position, the forward direction, the drilling

angle, the drilling depth, the drilling coordinates, and the

drilling pressure of the drilling unit 110. According to the exemplary embodiment, the detection unit 120 may include the plurality of sensors installed on respective parts of the drilling unit 110. To this end, the detection unit 120 may include a first antenna AT1, a second antenna AT2, a tilt sensor TS, a rotation angle sensor AS, and a pressure sensor

PS.

[69] The first antenna ATl may be installed in the rig RG and

may detect a position of the rig RG.

[70] The second antenna AT2 may be installed on top of the rod

RD and may detect a position of the rod RD. The second

antenna AT2 may be disposed on the top of the rod RD in order

to more accurately measure the position of the rod RD.

[71] For example, the first antenna ATl and the second antenna

AT2 may include at least one of a Global Navigation Satellite

System (GNSS) antenna or a GNSS receiver.

[72] The tilt sensor TS may measure a tilt angle of the rod RD.

For example, the tilt sensor TS may detect the tilt angle of

the rod RD with respect to at least one of axes on a three

dimensional (3D) coordinate plane.

[73] The pressure sensor PS may measure at least one of

collision pressure, feed pressure, and rotation pressure,

which are applied to the rod RD.

[74] According to the exemplary embodiment, the tilt sensor TS

and the pressure sensor PS may be installed on one side of the

rod RD.

[75]

[76] The control unit 130 may be implemented as a programmable

logic controller (PLC). However, the present disclosure is

not limited thereto, and according to the exemplary embodiment,

the control unit 130 may be implemented with a control circuit

such as a central processor unit (CPU), a microprocessor unit

(MPU), a microcontroller unit (MCU), and a graphic processor

unit (GPU). The programmable logic controller (PLC) may

process data and signals, which are input from the control

unit CR, and for example, may calculate bedrock strength on

the basis of the drilling pressure included in the drilling

information.

[77]

[78] The display unit 140 may include a display device DP.

The display device DP may provide interface images to a user

by visualizing the drilling information and the bedrock

strength. For example, the display device DP may be

implemented with a personal digital assistant (PDA), a

portable multimedia player (PMP), a wearable device, an e-book

device, a smart device, and the like. In addition, the

display device DP may display images in various display means

such as a light emitting diode (LED) device, a liquid crystal

display (LCD) device, and a plasma display panel (PDP) device.

[79]

[80] The communication unit 150 may store the drilling

information in real time in a server (e.g., the server device

300 shown in FIG. 1) by using a network. According to the

exemplary embodiment, the communication unit 150 may include

at least one of the satellite telecommunication module, the

wireless mobile communication module, the Bluetooth

telecommunication module, the Wi-Fi telecommunication module,

and the LoRa telecommunication module. To this end, the

communication unit 150 may include a first tracker TR1, a

second tracker TR2, and a third tracker TR3, which are for

wireless transmission and reception of data.

[81] The first tracker TR1 and the second tracker TR2 may

refer to respective communication modules for the first

antenna ATl and the second antenna AT2.

[82] The third tracker TR3 may refer to a communication module

to be connected to a wireless network (see FIG. 1).

[83] The drilling information may be transmitted to and stored

in the server device 300 (see FIG. 1) through the third

tracker TR3, and the transmitted data may be transferred to

the blasting design device 200 and used to revise and

supplement an existing blasting design.

[84] In addition, although not shown in FIG. 3, the drilling

device 100 may include a mount for mounting various components

and various cables for supplying power.

[85]

[86] FIG. 4 is a view illustrating the detection unit 120

according to the exemplary embodiment of the present

disclosure.

[87] Referring to FIGS. 2 and 3, the detection unit 120 may

include a first position detection unit 121, a second position

detection unit 122, a direction detection unit 123, an angle

detection unit 124, a depth detection unit 125, a coordinate

detection unit 126, and a pressure detection unit 127.

[88] The first position detection unit 121 may detect a

position of the drilling unit 110 by using the first antenna

ATl installed in the rig RG of the drilling unit 110.

[89] The second position detection unit 122 may detect a

position of the rod RD by using the second antenna AT2

installed on the rod RD of the drilling unit 110.

[90] The direction detecting unit 123 may detect a forward

direction of the drilling unit 110 on the basis of position

information collected from the first position detection unit

121 and the second position detection unit 122. That is, the

first antenna ATl and the second antenna AT2 may be disposed

along a center line (i.e., the forward direction) of the

drilling device 100. Accordingly, the direction detection

unit 123 may detect the forward direction of the drilling unit

110 on the basis of the location information collected through

the first antenna ATl and the second antenna AT2.

[91] Specifically, the direction detection unit 123 may

convert latitude and longitude information collected from the

antennas into a direction in which the drilling device is

facing. The direction detection unit 123 collects two kinds

of data on latitudes and longitudes from the antennas

installed on the rig RG and the rod RD, and calculates a

position of a mast on the basis of the location information of

a vehicle, so that a forward direction of the equipment may be

calculated. In the present specification, the mast may refer

to a structure for supporting the rod RD along an outer

surface of the rod RD.

[92]

[93] By using the tilt sensor TS installed on the rod RD, the

angle detection unit 124 may detect a tilt angle at which the

rod RD is tilted with respect to at least one axis. For

example, the at least one axis may refer to an x-axis, a y

axis, or a z-axis of a virtual coordinate system.

Specifically, the angle detection unit 124 may convert tilt

information collected from the tilt sensor TS into an angle at

which the mast of the equipment is tilted. In this case, the

angle detection unit 124 may divide tilts by the x and y axes

and calculate tilt angles tilted from respective axes.

[94]

[95] The depth detection unit 125 may detect a rotation angle

of the feed motor FM by using the rotation angle sensor AS installed in the feed motor FM of the drilling unit 110. In addition, the depth detection unit 125 may convert the detected rotation angle into a drilling depth for a blasting hole.

[96] Specifically, the depth detection unit 125 may convert

rotation information collected from the rotation angle sensor

AS (e.g., an encoder) into a drilling depth. The depth

detection unit 125 may convert a rotation angle of the motor

into the drilling depth on the basis of a length and a pitch

interval of each rod RD. In particular, when a rod RD is

added, the depth detection unit 125 may not perform the

conversion to the drilling depth even when the feed motor FM

rotates by receiving an additional signal from a central

control device (e.g., the control unit 130, see FIG. 1) of the

equipment. In addition, the depth detection unit 125 may

receive a signal from the central control device after the rod

RD is added, and may convert the rotation information of the

feed motor FM to the drilling depth again.

[97] For example, the depth detection unit 125 may determine

whether the rod RD is added or not. In a case where the rod

RD is added, the depth detection unit 125 may stop detecting a

rotation angle even when the feed motor FM rotates while the

rod RD is being added. Accordingly, according to the

exemplary embodiment of the present disclosure, when the depth

is detected, the depth detection unit 125 excludes the rotation angle at which the feed motor FM rotates in order to add the rod RD, so that an accurate drilling depth may be measured.

[98] In addition, the depth detection unit 125 may determine

the type of the newly added rod RD. In addition, after the

rod RD is added, the depth detection unit 125 may detect the

rotation angle of the feed motor FM again and measure an

accurate drilling depth by applying a pitch distance according

to the type of the newly added rod.

[99] The coordinate detection unit 126 may calculate drilling

coordinates representing a landing point of the rod RD with

respect to the ground in the three-dimensional space on the

basis of a height of the second antenna AT2 from a reference

plane, an azimuth angle of the rod arm RA supporting the rod

RD, and a drilling angle of the rod RD.

[100]Specifically, the coordinate detection unit 126 may

convert position information of a mast or rod RD of the

equipment and information on azimuth angles and drilling

angles into coordinates of the landing point on the ground

where drilling is actually performed. By using a distance

between the second antenna AT2 and the ground, the azimuth

angle, and the drilling angle, the coordinate detection unit

126 may calculate the coordinates of the landing point of the

drilling on the basis of the coordinates of the mast in the

three-dimensional space. In this case, the azimuth angle may be calculated from a direction of a vehicle body and tilts obtained from respective directions of the x-y axes.

[101]For example, the height of the second antenna AT2 from

the reference plane (e.g., the ground or a plane including the

expected landing point) represents a position of the uppermost

end of the rod RD. Since a length of a rod RD is information

that may be obtained from the type of the rod RD, the

coordinate detection unit 126 may estimate drilling

coordinates of a landing point on the basis of the above angle

and the length of the rod RD. In addition, when the rod arm

RA is tilted with respect to a reference line (e.g., a center

line along the forward direction of the drilling device 100),

the coordinate detection unit 126 may estimate the drilling

coordinates of the landing point by using an azimuth angle at

which the rod arm RA is tilted. In this case, the azimuth

angle may be derived from the forward direction and a drilling

angle of the drilling unit 110. However, the present

disclosure is not limited thereto, and within the scope of

achieving the objectives of the present disclosure, the

coordinate detection unit 126 may calculate the drilling

coordinates of the landing point in various ways. According

to the exemplary embodiment, the coordinate detection unit 126

may calculate the coordinates of the landing point where a

lower point of the rod RD contacts the ground by using a

three-dimensional coordinate detector or a distance detector.

[102]The pressure detection unit 127 is installed on the rod

[104]FIG. 5 is a view illustrating the control unit 130

according to the exemplary embodiment of the present

disclosure.

[105]Referring to FIG. 5, the control unit 130 may convert the

pressure information collected from the pressure detection

unit 127 into strength of bedrock (i.e., hard rock, normal

rock, and soft rock). The collision pressure, feed pressure,

and rotation pressure are used to calculate specific energy,

so as to be converted into uniaxial compressive strength of

the bedrock on the basis of the specific energy, whereby the

bedrock may be classified according to the strength.

[106]To this end, the control unit 130 may include an energy

calculation unit 131, a compressive strength conversion unit

132, and a bedrock classification unit 133.

[107]The energy calculation unit 131 may calculate specific

energy on the basis of at least one of collision pressure,

feed pressure, and rotation pressure, which are detected by

the pressure detection unit 127 (see FIG. 4).

[108] The compressive strength conversion unit 132 may convert

the specific energy calculated by the energy calculation unit

131 into compressive strength of bedrock.

[109] The bedrock classification unit 133 may classify the

bedrock into any one of soft rock, normal rock, and hard rock

on the basis of the compressive strength.

[110] For example, the bedrock classification unit 133 may

classify bedrock as soft rock when compressive strength is 20

MPa or less, normal rock when the compressive strength is 50

MPa or more and 120 MPa or less, and hard rock when the

compressive strength is 200 MPa or more.
