Description

[Technical Field]

[0001] The present invention relates to an explosives loading system, an explosives loading method, and a face drilling machine. [Background technology]

[0002] In the construction of mountain tunnels by blasting, workers work in close proximity to the tunnel face to load explosives, including explosives and fillers (such as clay), into the explosive holes drilled in the tunnel face. This poses a major challenge to safety in terms of preventing the collapse of the tunnel face due to falling rocks and falling rocks. Furthermore, the task of loading explosives into the explosive holes involves repeated, simple steps of inserting the explosive material into the hole and poking it with a loading rod, making it a demanding and difficult task in terms of both the working environment and posture. As the frontal view of the tunnel face becomes larger and the number of explosive holes increases, issues such as a decrease in work safety, increased work discomfort, and prolonged loading times become even more pronounced. For the above reasons, there is a demand for an explosives loading system that can achieve high work safety, less work discomfort, and efficient loading work when loading explosives or other materials into a charge hole drilled in the working face.

[0003] Patent Document 1 discloses an explosive loading device that remotely loads explosives and charge materials into a charge hole. This explosive loading device includes an explosive supply device, a charge material supply device, a pressure feed device that pressure-feeds the supplied explosives or charge materials into the charge hole, and a control device that controls these various devices. The charge material supply device includes a single transport device for transporting the charge materials from the charge material storage area to the charge material drop section, one or more storage devices that store multiple charge materials that drop from the charge material drop section, and multiple drop paths that guide the charge materials that drop from the bottom ends of the one or more storage devices to the loading hose. In this explosive loading device, the explosives supplied from the explosive supply device and the charge material supplied from the charge material supply device are sent individually to one loading machine, and then individually pressure-fed to the charge hole by a pressure-feeding device via a filling hose and a filling pipe connected to the loading machine.

[0004] [Patent Document 1] Japanese Patent Application Publication No. 2019-113197 Summary of the Invention [Problem to be solved by the invention]

[0005] According to the explosive loading device described in Patent Document 1, explosives and fillers can be loaded into a charging hole by remote control, which improves operational safety and reduces the laboriousness of the work. However, since multiple loads (explosives, etc.) are individually pumped and loaded into the charging hole, in other words, multiple loads cannot be loaded consecutively or simultaneously, there is room for improvement in the efficiency of the loading work.

[0006] The present invention aims to provide an explosive loading system that can achieve high operational safety, less laborious work, and efficient loading work when loading multiple materials into explosive holes drilled in a tunnel face, as well as a tunnel face drilling machine equipped with this explosive loading system and an explosive loading method. [Means for solving the problem]

[0007] In order to achieve the above object, one aspect of the explosive loading system according to the present invention comprises: An explosives loading system that loads a charge containing at least an explosive into a charge hole formed in a face, A supply device that supplies the material to be charged; a delivery device that delivers the charge supplied from the supply device to the charging hole; a control device that controls the supply device and the delivery device, The delivery device includes a delivery system through which the object is delivered, and a delivery means for moving the object in the delivery system, The delivery system includes a first system that receives the charged material from the supply device, and a second system that delivers the charged material transferred from the first system to the charging hole; the supply device includes a parent die supply device that supplies a parent die having a wireless detonator, and an additional die supply device that supplies an additional die; A charging device for charging the wireless detonator is provided in either the first system or the second system.

[0008] According to this aspect, a loading material containing at least an explosive is supplied from a supply device to the first system of the delivery system that constitutes the delivery device, and multiple loading materials are delivered and loaded into the charging hole continuously or simultaneously (at once) by a delivery means via the second system, thereby enabling efficient loading operations to be realized. Furthermore, by providing a charging device for charging the wireless detonator provided in the parent die in either the first or second system that forms the delivery system, it is possible to continuously charge the wireless detonator and load it into the explosive hole of the parent die, etc., using a single explosive loading system.

[0009] Here, "a charge containing at least an explosive" includes a case in which the charge is only an explosive and a case in which the charge includes an explosive and a filler. The explosive also includes a parent die equipped with a wireless detonator and an additional die. The supply device includes a parent die supply device that supplies a parent die equipped with a wireless detonator and an additional die supply device that supplies additional dies, and may further include a filler supply device that supplies additional dies. For example, a case in which the parent die supply device, additional die supply device, etc. are arranged in series along the first system can be mentioned, and when multiple additional dies are supplied, multiple additional die supply devices may also be arranged in series.

[0010] Furthermore, the first system, which continuously supplies multiple explosives, such as parent and additional dies, and sends the supplied explosives to the second system, is preferably linear, and therefore the first system is preferably formed of a relatively rigid pipe. On the other hand, the second system, which sends the explosives supplied from the first system to the charge hole, has a length corresponding to the distance to the charge hole provided at the face, is easy for workers to handle, and is preferably formed of a combination of hose and pipe, as it is preferable that the second system has a certain degree of rigidity and can ensure linearity, just like the first system.

[0011] Another aspect of the explosive loading system according to the present invention is A check valve is provided between the first system and the second system, and the charging device is disposed in the first system.

[0012] According to this aspect, the check valve provided between the first and second systems prevents explosives and the like sent to the second system from returning to the first system. In addition, the charging device provided in the first system allows the charging device to charge the wireless detonator provided in the parent die that is stopped by the check valve.

[0013] In another aspect of the explosive loading system according to the present invention, The charging of the wireless detonator by the charging device is performed on the parent die abutting against the check valve while the check valve is controlled to be closed, or on the parent die abutting against an additional die abutting against the check valve.

[0014] According to this aspect, by controlling the check valve to close, it is possible to reliably charge the wireless detonator provided on the parent die that is abutting against the check valve and stopped in the first system, and the wireless detonator provided on the parent die that is abutting against the additional die that is abutting against the check valve and stopped in the first system, using the charging device.

[0015] In another aspect of the explosive loading system according to the present invention, a pre-addition die is brought into contact with the check valve, and the parent die is brought into contact with the pre-addition die, and in this state, the wireless detonator is charged by the charging device; The control device receives a charging completion signal from the parent die and controls to open the check valve, causes the additional die supply device to supply a separate additional die to the first system, and causes the delivery means to deliver the preceding additional die, the parent die, and the separate additional die simultaneously.

[0016] According to this aspect, in a loading form in which a leading additional die preceding the parent die is loaded, the control device closes the check valve to stop the leading additional die and the parent die, receives a charging completion signal notifying completion of charging of the wireless detonator provided in the parent die, and controls the check valve to open, and the control device further supplies a separate additional die from the additional die supply device to the first system and controls the feeding means to feed out the leading additional die, parent die, and separate additional die simultaneously, thereby realizing continuous and smooth charging of the wireless detonator and loading of multiple loads into the charge hole.

[0017] Another aspect of the explosive loading system according to the present invention is In the control of the parent die supply device and the additional die supply device by the control device, a first mode in which the parent die and a plurality of additional dies are supplied to a first system; A second mode in which a plurality of the additional dies are supplied to the first system is selectably provided.

[0018] According to this embodiment, two types of loading modes can be implemented by freely selecting between a first mode (a mode involving charging of the parent die) in which a parent die and an additional die are supplied, and a second mode (a mode in which only explosives are loaded) in which multiple additional dies are supplied.

[0019] In another aspect of the explosive loading system according to the present invention, The delivery means includes a first delivery means for moving the charged material from the first system to an intermediate position of the second system, and a second delivery means for moving the charged material from an intermediate position of the second system to the charging hole, the first delivery means is either a first pressure feeder or a unit consisting of a cylinder mechanism and a push rod that is reciprocated in the first system by the cylinder mechanism, The second delivery means is a second pressure feeder.

[0020] According to this aspect, by providing a first delivery means for moving the loaded material from the first system to an intermediate position in the second system, and a second delivery means for moving the loaded material from the second system to the charging hole, even if the total length of the first system and the second system is long, the loaded material can be smoothly moved in the first system and the second system and delivered to the charging hole. When the first delivery means is a first pump such as a compressor, the material supplied to the first system is pumped by the first pump through a check valve to a midway point in the second system. At this time, it is preferable that the pumping force of the first pump is set so that the material is pumped to a predetermined position in the second system by the weight of the material and the kinetic friction between the material and the first and second systems. Alternatively, a stopper may be provided at a predetermined position in the second system so that it can move in and out freely, and the stopper may extend into the inside of the second system before the first pumping machine pumps the loaded material, so that the loaded material pumped by the first pumping machine is stopped at a predetermined position in the second system by the stopper.

[0021] On the other hand, if the first feeding means is a unit consisting of a cylinder mechanism and a push rod that reciprocates in the first system using this cylinder mechanism, the cylinder mechanism is driven to use the push rod to feed the loaded material to a predetermined position in the second system, and then the cylinder mechanism is driven to return the push rod to its original position (a position upstream of the supply device in the first system in the pushing direction), thereby creating a state ready for pushing in the next loaded material.

[0022] The second compressor that sends the charged material to the charging hole in the second system is formed by, for example, a compressor, etc. Here, when the second compressor supplies compressed air to the second system, lubricating water is simultaneously supplied to the second system, and the charged material and lubricating water are sent to the charging hole by the compressed air.

[0023] In another aspect of the explosive loading system according to the present invention, When the first delivery means is a unit consisting of the cylinder mechanism and the push rod, The first system is characterized in that a stopper is provided to forcibly stop the movement of the push rod.

[0024] According to this aspect, the first system is provided with a stopper that forcibly stops the movement of the pusher rod that forms the first delivery means, thereby preventing the pusher rod from pushing the parent die or the additional die too far and damaging them. For example, one example of a control configuration is one in which the pusher rod is equipped with a pressure sensor or the like, and the pusher rod slowly pushes the preceding additional die and the parent die until they reach the check valve, and the pusher rod receives a predetermined pressure from the parent die that is stopped by the check valve, and when the pressure reaches the predetermined value, the control device activates the stopper, instantly stopping the pusher rod from pushing in.

[0025] In another aspect of the explosive loading system according to the present invention, the supply device includes a storage container that stores a plurality of the objects to be loaded, and a supply mechanism that receives one of the objects from the storage container and supplies it to the first system; the supply mechanism includes an actuator and a rotating body that receives the object to be loaded through an opening while being rotated by the actuator; When the opening of the rotor is oriented in the direction of the first system, the material to be charged is supplied to the first system through the opening, The parent die includes a wireless detonator and an explosive in series, and the wireless detonator has a larger outer diameter than the explosive, When the feeding device is also the parent die feeding device, the rotating body is characterized by including a first rotating body having a first opening specific to the wireless detonator and a second rotating body having a second opening specific to the explosive.

[0026] According to this aspect, the charge supplied from the storage container is received by a rotor having an opening, and when the rotor rotates and the opening is oriented toward the first system, the charge is supplied (e.g., dropped) into the first system, thereby making it possible to efficiently and reliably supply a predetermined amount of charge to the first system. Also, when the supply device is a parent die supply device, the rotor includes a first rotor having a first opening specific to the wireless detonator and a second rotor having a second opening specific to the explosive, so that a single rotor (a unit of the first rotor and the second rotor) can receive parent dies consisting of a wireless detonator and an explosive with different outer diameters without rattle and supply them to the first system.

[0027] Further, one aspect of the face drilling machine according to the present invention is The first carriage and a boom attached to the first carriage so as to be rotatable and capable of being raised and lowered; The supply device and the control device constituting the explosive loading system are mounted on the first carriage or on a separate second carriage, A part or all of the second system is mounted on the boom.

[0028] According to this aspect, by using a face drilling machine equipped with the explosive loading system of the present invention, the tip of the second system is positioned at the charge hole to be loaded while moving and extending the boom, and the explosive loading system is operated to continuously load the main die, additional dies, etc. into the charge hole, thereby realizing remote work that separates the worker from the face and eliminating the need for the worker to work close to the face, thereby improving work safety and eliminating the laboriousness of the work. Furthermore, by using a face drilling machine equipped with an explosive loading system, efficient loading work can be achieved. Here, the face drilling rig may be equipped with one or more booms, with a man cage attached to the tip of the boom, and a worker in the man cage may position the tip of the second line of the explosive loading system in the charge hole. Even in this case, the worker in the man cage can position the tip of the loading pipe, etc. that make up the second line, in the charge hole while standing, for example, 2 m or more away from the face (there is evidence that being within 1.5 m of the face is dangerous), thereby ensuring the safety of the worker.

[0029] Further, one aspect of the explosive loading method according to the present invention is to An explosive loading method for loading a charge containing at least an explosive into a charge hole formed in a tunnel face, A step A of supplying at least the explosive from a supply device to a delivery system constituting a delivery device; and a step B of continuously moving at least a plurality of the explosives through the delivery system to sequentially load them into the charging holes, The explosive includes a parent die and a booster die equipped with a wireless detonator; The delivery system includes a first system that receives the charged material from the supply device and a second system that delivers the charged material moved from the first system to the charging hole, In the step B, in either the first system or the second system, after the wireless detonator is charged, the parent die and the additional die are simultaneously moved to the charging hole.

[0030] According to this aspect, a loading material containing at least an explosive is supplied from a supply device to the first system of the delivery system that constitutes the delivery device, and multiple loading materials are delivered and loaded into the charging hole continuously or simultaneously (at once) by a delivery means via the second system, thereby enabling efficient loading operations to be achieved. Furthermore, in either the first or second system that forms the delivery system, the wireless detonator provided on the parent die is charged, and then the parent die and additional die are simultaneously moved to the charge hole and loaded, thereby enabling the charging of the wireless detonator and the loading of the parent die, additional die, etc. into the charge hole to be carried out continuously. [Effects of the Invention]

[0031] According to the explosive loading system, explosive loading method, and face drilling machine of the present invention, the work of loading explosives or other materials into a charge hole drilled in the face can be carried out with high work safety, with less work discomfort, and with efficient loading work.

[0033] Hereinafter, an explosives loading system, an explosives loading method, and a face drilling machine according to embodiments will be described with reference to the accompanying drawings. In this specification and drawings, substantially identical components will be designated by the same reference numerals, and redundant description may be omitted.

[0034] [Explosive loading system, explosive loading method, and face drilling machine according to the embodiment] An example of an explosive loading system and explosive loading method, and a face drilling machine according to an embodiment will be described with reference to Figures 1 to 15. Here, Figure 1 is a diagram showing the overall configuration of an example of a face drilling machine according to an embodiment, and also shows the overall configuration of an example of an explosive loading system according to the embodiment. Figure 2 is a perspective view showing the configuration around a rotation unit at the tip of the boom of the face drilling machine. Also, Figures 3(a) to 3(c) are all schematic diagrams showing an example of the order in which explosives are loaded into the charge hole, and Figure 4 is a schematic diagram showing the overall configuration of an example of a parent die equipped with a wireless detonator.

[0035] Figure 1 shows a situation in which multiple charging holes H are formed at a tunnel face K, which is created in the process of constructing a mountain tunnel by drilling bedrock G through blasting, and a tunnel face drilling machine 100 is positioned on the tunnel entrance side of the tunnel face K, and multiple materials P1, P2, etc. (see Figure 3) are loaded into each charging hole H.

[0036] The face drilling machine 100 comprises a first carriage 10 and a plurality of booms 14, 16 attached to the first carriage 10 so as to be able to rotate and rise and fall freely (in the X1 direction and the X3 direction), and an explosive loading system 80 is mounted on the first carriage 10. Here, although not shown, the explosive loading system 80 may be mounted on a second carriage for transportation in addition to the first carriage 10 constituting the face drilling machine 100.

[0037] The carriage 10 has an operator cabin 12, which houses a control device 60 that constitutes an explosives loading system 80.

[0038] One of the booms 14 attached to the cart 10 is a cage boom with a man cage 15 at its tip that can rotate freely and can also extend and retract in the axial direction X4.The man cage 15 can always maintain a horizontal position as the cage boom 14 rises and falls in the X3 direction, allowing a worker on board the man cage 15 to perform various tasks and give instructions to the operator.

[0039] On the other hand, the other boom 16 attached to the carriage 10 is a work boom for carrying out explosive loading work etc., and is extendable in the axial direction X2 and has a rotation unit 17 at its tip.

[0040] As shown in Figure 2, around the rotation unit 17, in addition to the loading pipe 43c that constitutes the explosive loading system 80, a drilling rod 49A that constitutes a drilling system (not shown) and a cleaning rod 49B that constitutes a charge hole cleaning system (not shown) are attached.

[0041] By rotating the rotary unit 17 in the X10 direction, the selected pipe or rod can be put into an operating state. For example, first, the drilling rod 49A is selected, and the drilling system is driven to create a charge hole H at the working face K. Next, the rotary unit 17 is rotated to position the cleaning rod 49B in the charge hole H, and the cleaning rod 49B is inserted into the charge hole H, and the charge hole cleaning system is driven. The charge hole H is cleaned by spraying high-pressure air or high-pressure water from the cleaning rod 49B (or by applying a cleaning tool on a screw). Thereafter, the rotary unit 17 is rotated to position the loading pipe 43c in the charge hole H, and the loading pipe 43c is inserted into the charge hole H as shown in FIG. 1, and a charge containing an explosive is loaded into the charge hole H.

[0042] In this way, by arranging multiple types of work rods and pipes in the rotary unit 17, it becomes possible to continuously perform multiple types of work with one boom 16. Here, although one work boom 16 is shown in Fig. 1, multiple work booms may be provided on the carriage 10, and the multiple work booms may be equipped with rods and pipes specific to each type of work (drilling work, cleaning work, loading work).

[0043] As shown in FIG. 3, there are various modes for the order in which multiple types of explosives are loaded into the charge holes H formed in the tunnel face K.

[0044] The explosives used in the illustrated example are a parent die P1 (an example of a loaded material) and additional dies P2 and P3 (other examples of loaded materials), and the additional die that is loaded into the charge hole H before the parent die P1 is called the leading additional die P2, while the additional die that is loaded after the parent die P1 is called a separate additional die P3.

[0045] As shown in Figure 4, the parent die P1 has an explosive Pa and a wireless detonator Pb connected in series, and the wireless detonator Pb is formed by winding a power receiving coil Pd in ​​a circular shape around the outer periphery of a detonator body Pc, and embedding a detonator ignition part Pe protruding from one end of the detonator body Pc in the explosive Pa.

[0046] The wireless detonator Pb shown in the illustration is not a wired detonator or a wireless detonator with a built-in battery that stores the power required for detonation, etc., but a type of detonator that charges power wirelessly before (just before) loading the parent die into the charge hole H.

[0047] Wired detonators have the problem that the process of connecting the detonator and detonator with a wire is time-consuming and cumbersome, and the wiring process can be dangerous.

[0048] On the other hand, in the case of a detonator with a built-in battery, power decreases due to natural discharge between the time the detonator is manufactured and the time it is consumed, and there is a risk that the battery will run out at the time of detonation.

[0049] In contrast, the parent die P1 equipped with the illustrated wireless detonator Pb, which is charged before being loaded into the charge hole H, solves all of the above-mentioned problems.

[0050] The loading form shown in Fig. 3(a) is a first loading sequence in which, from the back of the charging hole H, a leading additional die P2, a parent die P1 (with the wireless detonator Pb at the back and the explosive Pa at the hole opening), and two separate additional dies P3 are arranged. Here, the number of separate additional dies P3 may be one or three or more.

[0051] On the other hand, the loading form shown in Figure 3(b) is the second loading sequence, in which, from the back of the charging hole H, a parent die P1' (with the wireless detonator Pb at the back and the explosive Pa at the hole mouth) equipped with a cushioning material Pf at its tip, and two separate additional dies P3 are lined up.

[0052] Furthermore, the loading form shown in Figure 3(c) is a third loading order form in which two advance dies P2 and a parent die P1 (explosive Pa is at the back and wireless detonator Pb is at the hole mouth side) are lined up in order from the back of the charge hole H.

[0053] In the first and third forms, the presence of the advance die P2 at the back of the charge hole H prevents the wireless detonator Pb provided on the parent die P1 from being damaged by the impact during loading.

[0054] Furthermore, in the case where there is no advance die P2 and the parent die P1' is positioned at the rear, as in the second form, and the wireless detonator Pb is positioned even further rearward, the presence of a cushioning material Pf at the tip of the wireless detonator Pb prevents damage to the wireless detonator Pb when it collides with the rear of the charge hole H.

[0055] As described above, there are various patterns for the order in which multiple explosives are loaded, but the following description will focus on the loading pattern shown in FIG. 3(a).

[0056] Although the illustrated example shows a form in which only explosives are loaded, a loading method in which additional fill material is loaded on the mine entrance side is also possible, in which case the explosives loading system should further be equipped with a supply device for supplying the fill material.

[0057] The explosive loading system 80 mounted on the carriage 10 that constitutes the face drilling machine 100 includes a supply device 20 that supplies additional dies P2, P3, which are the loaded items, a supply device 30 that supplies the parent die P1, which is the loaded item, a delivery device 40 that delivers the additional dies P2, P3 and parent die P1 supplied from the supply devices 20, 30 to the explosive hole H, and a charging device 50 that charges the wireless detonator Pb that forms the parent die P1.

[0058] The illustrated explosive loading system 80 further includes a control device 60 that controls the feeding devices 20 and 30, the delivery device 40, and the charging device 50.

[0059] On the carriage 10, three supply devices 20A to 20C each accommodating a plurality of additional dies P2, P3 and one supply device 30 accommodating a plurality of parent dies P1 are arranged in parallel in series above and along the first system 42 that constitutes the delivery device 40.

[0060] The multiple supply devices 20A, 20B, 20C, and 30 arranged in series each supply additional dies P2, P3 and parent die P1 to be loaded into the multiple charging holes H to the first system 42 in the Y1 and Y2 directions.

[0061] 3(a), a leading additional die P2 is supplied from the supply device 20A, and further a parent die P1 is supplied from the supply device 30, and the leading additional die P2 and the parent die P1 are sent to the check valve 44. Next, a separate additional die P3 is supplied from the supply devices 20B and 20C, and the separate additional die P3 is sent to the rear of the parent die P1, which is stopped by the check valve 44.

[0062] A drive command signal is sent from the control device 60 to the supply devices 20, 30, and the supply devices 20, 30 are driven to supply the additional dies P2, P3 and the parent die P1 to the first system 42. The specific configuration of the supply devices 20, 30 will be described in detail below.

[0063] The delivery device 40 has a delivery system 41 that forms a route for delivering the additional dies P2, P3 and the parent die P1 supplied from the supply devices 20, 30, a check valve 44 consisting of a ball valve interposed in the delivery system 41, and two types of delivery means, namely, a first delivery means 45 and a second delivery means 46.

[0064] The delivery system 41 has a first system 42 that receives the additional dies P2, P3 and the parent die P1 from the supply devices 20, 30, and a second system 43 that delivers the additional dies P2, P3 and the parent die P1 that have moved from the first system 42 to the charging hole H.

[0065] The first system 42 receives the additional dies P2, P3 and the parent die P1 from each of the supply devices 20A to 20C, 30 arranged in series and sends them out to the second system 43, so it requires linearity, and therefore it is preferable that it be formed by a loading pipe made of a relatively rigid steel pipe, hard resin, etc.

[0066] On the other hand, the second system 43 has a relatively long length from the boundary with the first system 42 to the charging hole H of the face K, and preferably has good handleability for workers at its intermediate position, and further, preferably has linearity at the tip region for insertion into the charging hole H. Therefore, it is preferable that the side connected to the first system 42 has a loading pipe 43a that can ensure linearity, the intermediate position has a loading hose 43b that has good handleability, and the tip side of the charging hole H has a unit structure that has a loading pipe 43c. The loading hose 43b is formed from a material that has both a certain degree of rigidity and deformability, such as a relatively hard resin or a corrugated tube.

[0067] A check valve 44 made of a ball valve is provided at the boundary between the first system 42 and the second system 43. A first delivery means 45 is provided on the upstream side (tunnel entrance side) of the first system 42 in the delivery direction, and after each material to be charged is supplied to the first system 42, a drive command signal is sent from the control device 60 to the first delivery means 45, and the first delivery means 45 is driven to deliver the material to be charged in the Y3 direction to the check valve 44 and further to an intermediate position in the second system 43 (for example, an intermediate position in the charging pipe 43a).

[0068] The multiple load items (pre-loading die P2, parent die P1, and two separate loading dies P3) that pass through the check valve 44 and are sent to an intermediate position in the second system 43 are stopped at an intermediate position in the loading pipe 43a, and are prevented by the check valve 44 from returning to the first system 42 (reverse running).

[0069] The ball valve forming the check valve 44 is a control valve having a rotor 44a with a through hole 44b, and the control device 60 sends a drive command signal to close the check valve 44 to stop the leading additional die P2 and the parent die P1 and charge the wireless detonator Pb of the parent die P1 using the charging device 50. After charging of the wireless detonator Pb is completed, when two additional dies P3 are sent behind the parent die P1, the control device 60 sends a drive command signal to the check valve 44 to open it, and the leading additional die P2, the parent die P1, and the two additional dies P3 pass through the through hole 44b in the Y6 direction and are sent out to a midpoint in the second system 43, and the control device 60 sends a drive command signal to close it again.

[0070] Here, the check valve 44 may be a ball valve as shown in the example, or may be a check valve whose opening is freely adjustable, or a valve with a hinge structure that automatically closes when the parent die P1 is stopped to charge the wireless detonator Pb, or when the parent die P1 etc. is sent from the first system 42 to the second system 43.

[0071] After the leading additional die P2, the parent die P1, and the two separate additional dies P3 are sent to an intermediate position in the second system 43 and the ball valve 44 is controlled to be closed, a drive command signal is sent from the control device 60 to the second sending means 46 connected to the loading pipe 43a, and by driving the second sending means 46, the leading additional die P2, the parent die P1, and the two separate additional dies P3 are continuously sent to the loading hose 43b and the loading pipe 43c in the Y7 direction and the Y8 direction, and are continuously loaded into the charging hole H.

[0072] Here, the first delivery means 45 that delivers the parent die P1 and the like in the first system 42 is a unit formed by a cylinder mechanism 45a and a push rod 45b that is reciprocated by the cylinder mechanism 45a in the first system 42. Note that the first delivery means 45 may be a first pump formed by a compressor, or the like, in addition to the unit in the illustrated example, and the parent die P1 and the like may be pressure-fed by compressed air supplied from the first pump to the first system 42.

[0073] On the other hand, the second delivery means 46, which continuously delivers the leading die P2, the parent die P1, etc. in the second system 43, is a second pressure pump formed by a compressor. A flow path connecting the second pressure pump 46 and the second system 43 is connected to a flow path leading to a water tank 47, and lubricating water supplied from the water tank 47 in the Y5 direction is supplied to the second system 43 by compressed air pumped from the second pressure pump 46 in the Y6 direction, and the leading die P2, the parent die P1, etc. and the lubricating water are pumped to the charging hole H by the compressed air.

[0074] Next, the configuration of the additional die supply device 20 will be described in detail with reference to Figures 5 and 6, and the configuration of the parent die supply device 30 will be described with reference to Figures 7 and 8. Here, since the basic configuration of the parent die supply device 30 is roughly the same as the basic configuration of the additional die supply device 20, the configuration of the additional die supply device 20 will be described in detail, and the parent die supply device 30 will be described below focusing only on the features of the configuration that differ from the additional die supply device 20.

[0075] Fig. 5 is a side view of the inside of an example of a supplying device that supplies an additional die, Fig. 6 is a view showing a state in which a storage container protrudes from an outer box in an example of a supplying device that supplies an additional die, Fig. 7 is a front view of the inside of an example of a supplying device that supplies a parent die, and Fig. 8 is a view taken along arrows VIII-VIII in Fig. 7.

[0076] The illustrated example of the additional die supply device 20 has an outer box 21 with an opening 21b on the front surface 21a, a storage container 22 housed inside the outer box 21 so as to be freely accessible through the opening 21b, and a supply mechanism 23 that receives one additional die P2, P3 from the storage container 22 and supplies it to the first system 42.

[0077] In the illustrated example, the three supply devices 20A, 20B, and 20C installed side by side all have the same structure, and a first system 42 is disposed below each supply device 20. The following description focuses on the supply device 20A that supplies the additional die P2.

[0078] As shown in Figure 6, the storage container 22 slides forward in the Z1 direction from the outer box 21 and protrudes outward. When the storage door 22d, which is attached to the side of the storage container 22 via a hinge so as to be freely opened and closed, opens forward, the inside of the storage container 22 is opened and multiple additional dies P2 can be stored in an aligned and stacked state from the side of the storage container 22.

[0079] 5, a discharge door 22b is provided below the front surface 21a of the outer box 21 via a hinge so as to be able to open and close freely, and almost the entire area of ​​the discharge door 22b is formed by a transparent plate 22e, through which the interior can be seen. When the storage container 22 is housed in the outer box 21, the front surface 22a of the storage container 22 is positioned above the discharge door 22b, and both are locked with a lock key (not shown). To slide the storage container 22 out of the outer box 21, the lock key is released and the container is pulled out forward.

[0080] As shown in Figure 6, a slide rail 22g incorporating multiple wheels is provided at the upper end of the storage container 22, and a slide rail 21c incorporating multiple wheels is also provided above the outer box 21. When both slide rails 21c and 22g are aligned and the wheels on both rotate, the storage container 22 is pulled forward in the Z1 direction from the outer box 21, and when pushed in the opposite direction, it is stored in the outer box 21.

[0081] As shown in Figures 5 and 6, the storage container 22 includes an upper storage section 22A that stores a large number of additional dies P2, P3 in an aligned and stacked state, and a lower supply section 22B that extends from below the upper storage section 22A, aligns a plurality of load objects P in a row, and supplies the additional dies P2 one by one to the supply mechanism 23.

[0082] The upper storage section 22A is large enough to store a large number of additional dies P2, P3 at once, and the lower supply section 22B supplies the additional dies P2 one by one downward from the upper storage section 22A. The lower supply section 22B has a linear shape that extends obliquely downward from one end (the front end in the illustrated example) of the upper storage section 22A, bends, and extends vertically downward.

[0083] The vertical height of the lower supply section 22B is approximately the same as the cross-sectional diameter of the cylindrical adding die P2, and this height and linearity allow the adding dies P2 to be gently fed one by one in the Z7 direction and supplied to the supply mechanism 23 located below. This makes it possible to prevent the adding dies P2 from being damaged by sudden and violent feeding.

[0084] 5, one end of bottom surface 24 of upper storage section 22A is pivot end 24d, and pivot end 24d is provided with pivot shaft 24e. A piston rod of first actuator 25 formed by a cylinder mechanism is attached to the underside of bottom surface 24 at a midpoint. Furthermore, an end of region 24a on the lower supply section side of bottom surface 24 is provided with bent portion 24b bent in a dogleg shape.

[0085] By operating the first actuator 25 and reciprocating the piston rod diagonally up and down in the Z5 direction, the bottom surface 24 rotates slightly up and down around the rotation axis 24e, and this up and down rotation causes the bottom surface 24 to reciprocate diagonally up and down in the Z6 direction.

[0086] By this reciprocating movement of the bottom surface 24, even when a large number of additional dies P2 are densely accommodated inside the upper accommodation section 22A as shown in FIG. 6, the reciprocating movement of the bottom surface 24 can release the tightly fixed state of the multiple additional dies P2, preventing the multiple additional dies P2 from getting stuck inside the upper accommodation section 22A and becoming unable to move, while ensuring the movement of the additional dies P2 to the lower supply section 22B.

[0087] In this way, the bottom surface 24 reciprocates vertically around the rotation axis 24e, and this action pushes up the multiple additional dies P2 from below, releasing them from their tightly fixed state, so it can also be called a spring plate.

[0088] Furthermore, a bent portion 24b bent in a dogleg shape is provided at the end of the region 24a on the lower supply section side of the bottom surface 24, which prevents some of the additional dies P2 from entering the lower space 24c of the bottom surface 24 when the bottom surface 24 is raised upward. This prevents the additional dies P2 from entering the lower space 24c and hindering the reciprocating movement of the bottom surface 24.

[0089] As shown in FIG. 5, in a state where the container 22 is housed inside the outer box 21, the additional die P2 is supplied from the container 22 to the supply mechanism 23 located below it.

[0090] The supply mechanism 23 has a second actuator 26 formed by a motor, and a rotating body 27 rotated by the second actuator 26. The rotating body 27 is provided with a receiving groove 27a, and when the receiving groove 27a is aligned with the lower supply section 22B, one additional die P2 is received by the receiving groove 27a.

[0091] The rotating body 27, in which the additional die P2 is received in the receiving groove 27a, rotates in the Z8 direction around the rotation axis, and when the receiving groove 27a reaches a diagonally downward position, the additional die P2 gradually starts to move by its own weight.

[0092] A guide 29 extending in a slightly curved diagonal direction is provided on the side of the rotating body 27 to gently guide the additional die P2 to the first system 42 below. The additional die P2 moves to the outside of the receiving groove 27a in accordance with the rotation of the rotating body 27, and is supplied to the first system 42 while being guided along the guide 29 without any impact.

[0093] A limit switch 28 (see FIG. 11) is further provided on the side of the rotating body 27, and when the limit switch 28 is pressed by the rotation of the rotating body 27, it is detected that one additional die P2 has been supplied to the first system 42. This detection result is transmitted from the limit switch 28 to the control device 60. Here, instead of the limit switch 28, a weight scale may be provided below the rotating body 27, and the weight scale may detect that the additional die P2 has been supplied to the first system 42 and also detect the weight of the additional die P2.

[0094] 5, a discharge door 22f is provided on the lower surface of the lower supply section 22B so as to be rotatable in the Z4 direction, and a separate discharge door 22b is provided on the front surface of the outer box 21 so as to be rotatable in the Z3 direction. A transparent plate 22e is provided on the discharge door 22b, and a slit (not shown) is provided in the discharge door 22f for checking the inside.

[0095] When removing the additional dies P2 from the storage container 22, one of the discharge doors 22b is rotated in the Z3 direction to open it, and then the other discharge door 22f is rotated in the Z4 direction to open it, thereby allowing multiple additional dies P2 to be continuously and efficiently discharged from the lower supply section 22B.

[0096] Furthermore, a transparent plate 22e is provided on the discharge door 22b, and a slit (not shown) for checking the inside is provided on the discharge door 22f, so that the inside of the lower supply section 22B and the rotating body 27 can be seen from the outside, and it can be confirmed that multiple additional dies P2 are moving without clogging in the lower supply section 22B, and that one additional die P2 is received in the correct posture in the receiving groove 27a of the rotating body 27, etc.

[0097] 6, a transparent plate 22e is also provided on a rotatable storage door 22d on the side of the storage container 22. This transparent plate 22e allows the storage positions of the many additional dies P2 stored in the storage container 22 to be confirmed.

[0098] On the other hand, the parent die supply device 30 shown in FIGS. 7 and 8 has an outer box 31 and a container 32 for accommodating a plurality of parent dies P1 housed inside the outer box 31 so as to slidably protrude forward.

[0099] 8, the supply device 30 in the illustrated example is a rotor 38 located below that supplies one parent die P1 to the first system 42, and there are three separate rotors 36 above that, with one parent die P1 provided for each rotor 36. Each of the three rotors 36 is rotated by its own actuator 35, and rotation of a selected actuator 35 rotates the corresponding rotor 36, thereby supplying one parent die P1 to the rotor 38 below.

[0100] The rotor 38 that has received one parent die P1 is rotated by the actuator 37 and supplies one parent die P1 to the first system 42.

[0101] In this way, the supply mechanism 33 forming the supply device 30 in the illustrated example is formed by three rotating bodies 36 and their respective actuators 35, and one rotating body 38 and its own actuator 37.

[0102] The rotor 36 is composed of a rotor 36b having an opening with an inner diameter equal to the outer diameter of the explosive Pa, and a rotor 36a having an opening with an inner diameter equal to the outer diameter of the wireless detonator Pb.

[0103] Similarly, the rotating body 38 is composed of a rotating body 38b having an opening with an inner diameter equal to the outer diameter of the explosive Pa, and a rotating body 38a having an opening with an inner diameter equal to the outer diameter of the wireless detonator Pb.

[0104] In this way, each of the rotating bodies 36, 38 has a rotating body with an opening having an inner diameter equal to the outer diameter of the explosive Pa, which has a different outer diameter from the other, and a rotating body with an opening having an inner diameter equal to the outer diameter of the wireless detonator Pb, so that the parent die P1 can be received without any rattle and supplied to the first system 42.

[0105] Next, an example of the control content of the explosive loading system by the control device (an explosive loading method according to an embodiment) will be described with reference to Figures 9 to 15. Here, Figure 9 is a diagram showing an example of the hardware configuration of the control device, and Figure 10 is a diagram showing an example of the functional configuration of the control device. Also, Figures 11 to 14 are process diagrams of an example of an explosive loading method according to an embodiment, respectively.

[0106] 9, the control device 60 includes a CPU (Central Processing Unit) 61, a main memory device 62, an auxiliary memory device 63, a communication IF (interface) 64, and an input / output IF 65, which are interconnected by a connection bus 66. The main memory device 62 and the auxiliary memory device 63 are computer-readable recording media. Note that the above components may be provided separately, or some of the components may not be provided.

[0107] The CPU 61 is also called an MPU (Microprocessor) or a processor, and may be a single processor or a multiprocessor. The CPU 61 is a central processing unit that performs overall control of the control device 60, which is a computer. The CPU 61, for example, deploys a program stored in the auxiliary storage device 63 in an executable manner in a working area of ​​the main storage device 62, and controls peripheral devices through the execution of the program, thereby providing functions that meet a predetermined purpose.

[0108] The main memory device 62 stores computer programs executed by the CPU 61, data processed by the CPU 61, etc. The main memory device 62 includes, for example, a flash memory, a random access memory (RAM), and a read-only memory (ROM). The auxiliary memory device 63 stores various programs and data on a readable and writable recording medium and is also referred to as an external memory device. The auxiliary memory device 63 stores, for example, an operating system (OS), various programs, various tables, etc. The OS includes, for example, a communication interface program that exchanges data with external devices connected via the communication IF 64. Examples of external devices include communication devices (none of which are shown) provided in the cylinder mechanism 45a, the second pump 46, the check valve 44, the limit switch 28, the charging device 50, etc. Note that the network includes a public network such as the Internet, a wireless network such as a mobile phone network, a dedicated network such as a virtual private network (VPN), a local area network (LAN), etc.

[0109] The auxiliary storage device 63 is used, for example, as a storage area that supplements the main storage device 62, and stores computer programs executed by the CPU 61, data processed by the CPU 61, etc. The auxiliary storage device 63 is a silicon disk including nonvolatile semiconductor memory (flash memory, EPROM (Erasable Programmable ROM)), a hard disk drive (HDD: Hard Disk Drive), a solid state drive, etc. Examples of the auxiliary storage device 63 include drives for removable recording media such as CD drives, DVD drives, and BD drives, and examples of removable recording media include CDs, DVDs, BDs, USB (Universal Serial Bus) memories, and SD (Secure Digital) memory cards.

[0110] The communication IF 64 is an interface with the network to which the control device 60 is connected. The communication IF 64 receives, via the network, detection data indicating that the additional dies P2 and P3 have been supplied to the first system 62 from the limit switch 28, and detection data indicating that the parent die P1 has been supplied to the first system 62 from the limit switch 39. When the wireless detonator Pb of the parent die P1, which is stopped by the check valve 44, is charged using the charging device 50, the communication IF 64 transmits a drive command signal to the charging device 50. When the parent die P1 or the additional dies P2 and P3 are to be sent out in the first system 42, the communication IF 64 transmits a drive command signal to the cylinder mechanism 45a. When the parent die P1 or the additional dies P2 and P3 are to be sent out to the charging hole H in the second system 43, the communication IF 64 closes the check valve 44 and then transmits a drive command signal to the second pumping machine 46.

[0111] The input / output IF 65 is an interface for inputting and outputting data between devices connected to the control device 60. For example, an input device such as a touch panel is connected to the input / output IF 65. The control device 60 receives operation instructions and the like from an operator who operates the input device via the input / output IF 65.

[0112] In addition, the input / output IF 65 is connected to a display device such as a liquid crystal panel (LCD: Liquid Crystal Display) or an organic EL panel (EL: Electroluminescence), and an output device such as a speaker. For example, of the charge holes H at the working face K stored in the control device 60, the charge hole H to be loaded with the material to be charged is displayed on the display device.

[0113] 10 , the control device 60 provides various functions, such as at least a communication unit 102, a supply device drive unit 104, a check valve drive unit 106, a delivery device drive unit 108, a charger drive unit 110, a display unit 112, and a storage unit 114, by executing a program by a CPU 61. Note that at least a part of the processing functions may be provided by a DSP (Digital Signal Processor), a GPU (Graphics Processing Unit), or the like, and similarly, at least a part of the processing functions may be provided by a dedicated LSI (Large Scale Integration) such as an FPGA (Field-Programmable Gate Array), a numerical calculation processor, an image processing processor, or other digital circuits.

[0114] The communication unit 102 is communicably connected to the communication IFs of the supply devices 20, 30, the cylinder mechanism 45a, the second pressure pump 46, the check valve 44, the limit switches 28, 39, and the charging device 50 via a network.

[0115] As shown in FIG. 11, a drive command signal S0 is transmitted from the supply device driver 104 of the control device 60 to the supply device 20A that supplies the preliminary additional die, and the preliminary additional die P2 is supplied to the first system 42 from the supply device 20A.

[0116] Then, during the process of supplying from the supply device 20A to the first system 42, the limit switch 28 detects the passage of the advance addition die P2, and the detection data S1 is transmitted to the communication unit 102 of the control device 60, and the detection data received by the communication unit 102 is stored in the memory unit 114.

[0117] Further, the supply device driver 104 of the control device 60 transmits a drive command signal S2 to the supply device 30 that supplies the parent die P1, and the supply device 30 supplies the parent die P1 to the first system .

[0118] Then, during the process of supplying from the supply device 30 to the first system 42, the limit switch 39 detects the passage of the parent die P1, the detection data S3 is transmitted to the communication unit 102 of the control device 60, and the detection data received by the communication unit 102 is stored in the memory unit 114 (this is process A).

[0119] Upon storing these detection data in the memory unit 114, as shown in FIG. 12, a drive command signal S4 is sent from the check valve drive unit 106 of the control device 60 to the check valve 44, and after the check valve 44 is controlled to be closed, a drive command signal S5 is sent from the delivery device drive unit 108 to the cylinder mechanism 45a.

[0120] The cylinder mechanism 45a, which has received the drive command signal S5, operates the push rod 45b to feed the preliminary additional die P2 and the main die P1 supplied to the first system 42 toward the check valve 44 in the Y3 direction.

[0121] This delivery is carried out slowly, and when the preceding reinforcing die P2 reaches the check valve 44, which is controlled to be closed, the delivery by the pushing rod 45b is quickly stopped.

[0122] For example, a pressure sensor (not shown) may be attached to the tip of the push rod 45b, and when the pre-refill die P2 reaches the check valve 44 and the pressure sensor receives a predetermined pressure value, the cylinder mechanism 45a may instantly stop the push rod 45b from being fed out; or a stopper (not shown) may extend into the first system 42 and come into contact with the push rod 45b, thereby instantly stopping the push rod 45b from being fed out.

[0123] A charging device 50 is disposed in the first system 42. When the check valve 44 stops the preceding additional die P2 and the parent die P1, a drive command signal S6 is transmitted from the charging device driving unit 110 to the charging device 50.

[0124] The charging device 50, which has received the drive command signal S6, charges the wireless detonator Pb of the stopped parent die P1.

[0125] Here, the illustrated example shows a configuration in which the charging device 50 is arranged in the middle of the first system 42 and charges the wireless detonator Pb of the parent die P1 that is stopped in the first system 42, but it may also be a configuration in which the charging device 50 is arranged in the middle of the second system 43 and charges the wireless detonator Pb of the parent die P1 that is stopped in the second system 43.

[0126] When charging of the wireless detonator Pb of the parent die P1 is completed, a signal S7 indicating that charging is completed is transmitted from the charging device 50 to the control device 60. In this way, by proceeding to the next step after the control device 60 receives the signal S7 indicating that charging is completed, it is possible to prevent the parent die P1 in an incompletely charged state from being loaded into the charging hole H.

[0127] In addition, if a signal S7 indicating that charging is complete is not sent from the charging device 50 to the control device 60, the control device 60 will sound an alarm and turn on an alarm lamp, and the worker or other person who receives the alarm will take measures to remove the parent die P1 that has not yet completed charging from the first system 42.

[0128] In this case, as shown in the illustrated example, at the removal stage, only the preceding additional die P2 and the parent die P1 are present in the first system 42, so it is possible to reduce the number of objects to be removed from the first system 42. For example, if removal is performed in a state where a separate additional die P3 is present behind the parent die P1, the number of objects to be removed becomes relatively large, making the removal more time-consuming.

[0129] After the charging of the wireless detonator Pb of the parent die P1 is properly completed, the supply device driver 104 transmits drive command signals S8 and S9 to the two supply devices 20B and 20C, respectively, as shown in Fig. 13. Upon receiving the drive command signals S8 and S9, the supply devices 20B and 20C supply a separate additional die P3 to the first system 42.

[0130] Next, a drive command signal S10 is sent from the check valve drive unit 106 to the check valve 44, and after the check valve 44 receives the drive command signal S10 and is controlled to open, a drive command signal S11 is sent from the delivery device drive unit 108 to the cylinder mechanism 45a. The cylinder mechanism 45a receives the drive command signal S11 and operates the pushing rod 45b to deliver the preliminary additional die P2, the parent die P1, and the two separate additional dies P3 supplied to the first system 42 in the Y4 direction to an intermediate position in the second system 43 via the check valve 44, which is controlled to be open, and stop each of the objects to be charged.

[0131] Next, as shown in Figure 14, a drive command signal S12 is sent to the control valve 46a located in the flow path connecting the second pump 46 and the second system 43 to control it to open, and further, a drive command signal S13 is sent from the delivery device drive unit 108 to the second pump 46.

[0132] Upon receiving the drive command signal S13, the second compressor 46 supplies compressed air, which sends out the lubricating water supplied from the water tank 47 in the Y5 direction to the second system 43, while pushing the leading add-on die P2, parent die P1, and two separate add-on dies P3, which are stopped at predetermined positions, from the rear in the Y6 direction, and sending the leading add-on die P2, parent die P1, and two separate add-on dies P3 from the second system 43 to the charge hole H of the face K in the Y7 direction, thereby performing continuous loading of the leading add-on die P2, parent die P1, and two separate add-on dies P3 into the charge hole H (this is the end of process B).

[0133] The above series of operations can be performed by a remote control switch held by an operator. For example, Fig. 15 shows a remote control switch 70 that can select two supply modes and an example of how to operate the switch.

[0134] The normal mode, the parent die mode, is an operation mode that includes charging the wireless detonator Pb of the parent die P1, as explained above.

[0135] In contrast, the additional die mode is a mode in which only the additional die is loaded into the charge hole H, and does not include charging the wireless detonator.

[0136] By applying a remote control switch 70 as shown in the example, multiple modes can be appropriately selected, such as a mode in which the parent die P1 is charged and a mode in which charging is not performed, thereby realizing the appropriate loading of explosives, etc. into the charging hole H.

[0137] By using the face drilling machine 100 equipped with the explosive loading system 80 shown in the figure, workers no longer need to perform the difficult task of loading explosives close to the face K, thereby making it possible to achieve efficient loading work that is safer and less difficult when loading multiple materials such as explosives into the charging hole H drilled in the face K.

[0138] Furthermore, by providing a charging device 50 for charging the wireless detonator Pb provided in the parent die P1 in either the first system 42 or the second system 43 that form the delivery system 41, it is possible to continuously charge the wireless detonator Pb and load it into the explosive hole H of the parent die P1, etc., in a single explosive loading system 80.
