The present invention relates to an explosive bag for hole blasting and an explosive bag insertion device for hole blasting, which can easily position blasting explosives at intervals in a hole opened for blasting, and an explosive bag insertion for hole blasting. It is an invention about a device.

The general rock blasting method is to charge a detonator and explosives to a predetermined height inside a drilled blasting hole for a quarry tunnel that is deeply drilled to a preset depth on the rock to be broken, and to fill the upper part of the charge chamber with a filler material. Next is the blasting method.

In other words, the conventional rock blasting method had a problem in that it was difficult to charge explosives to the end of the drilling blasting hole for the quarry tunnel when the drilling hole for the quarry tunnel was dug deep.

In addition, with the conventional rock blasting method, it was difficult to confirm whether the initially introduced explosive was properly charged to the end of the drilling hole for the quarry mine.

In particular, when the drilling blasting hole for the quarry tunnel is drilled at an angle, it is difficult to charge explosives to the end of the drilling blasting hole for the quarry tunnel, and it is difficult to check the charging state of the explosives.

Therefore, the conventional rock blasting method took a long time to charge the explosives into the drilling blasting hole for the quarry tunnel, and there was a problem in that it was difficult to complete the blasting work at once, and as a result, the efficiency of the blasting work was greatly reduced. do.

In addition, an embodiment of the device for inserting the explosive bag 10 for drilling blasting according to the present invention may further include a reel rotation motor that rotates the bag winding reel unit 20 in both directions, although not shown.

The reel rotation motor rotates the pouch take-up reel unit 20 in both directions to unwind or wind the pouch main body 100 from the pouch take-up reel unit 20.

In addition, one embodiment of the explosive bag (10) injection device for drilling blasting according to the present invention is located on the reel supporter (30) and measures the bag length for detecting the length of the bag body portion (100) that is unwound from the bag winding reel portion (20). It may further include a detection unit 50 and a display unit 60 that displays the length of the pocket main body 100 detected by the pocket length detection unit 50.

As an example, the bag length detection unit 50 is a rotation speed sensor that detects the rotation speed or amount of rotation of the bag take-up reel unit 20.

The bag length detection unit 50 detects the bag length display unit 150, which displays the longitudinal direction of the bag main unit 100, and the bag main unit inserted into the drilling blasting hole for the quarry mine ( 100) may include a display detection unit that checks the length.

In addition, the pocket length detection unit 50 can be implemented in various modifications using a known sensor structure that can detect the length of the pouch main unit 100 that is unwound from the pouch reel unit 20. A more detailed description is provided. Please note that this is omitted.

One embodiment of the device for inserting the explosive bag (10) for drilling blasting according to the present invention is to release the bag from the bag winding reel unit (20) through the bag length detection unit (50) and the display unit (60) and into the drilling blasting hole for the quarry mine. By displaying the length of the inserted bag body 100, the worker can check the length at which the bag body 100 is inserted into the drilling and blasting hole for the quarry tunnel in real time during work.

The worker checks in real time the length at which the bag main part 100 is inserted into the drilling and blasting hole for the quarry mine, and if the bag main part 100 is not inserted smoothly during work, the bag main part 100 is inserted using the bag winding reel part 20. After partially winding (100) again, the operation of unwinding the bag winding reel part (20) is repeated, so that the bag main part (100) can be smoothly inserted into the drilling and blasting hole for the quarry tunnel by the load of the weight part (200). let it be

The operation of the reel rotation motor or reel brake unit 40 may be controlled by a control unit, and the control unit may include a control unit that can be operated by an operator.

The operator controls the operation of the reel rotation motor or reel brake unit 40 through the control unit to enable the bag body 100 to be smoothly inserted into the drilling blasting hole for the quarry mine, and to control the operation of the bag body 100. By checking the insertion depth in real time, it is possible to easily check whether the bag body part 100 has been inserted to the end of the drilling blasting hole for the quarry tunnel, thereby improving reliability during blasting work.

The present invention allows explosives to be smoothly charged into the drilled blasting hole for a quarry tunnel, so that during blasting work, blasting is possible while the explosive is charged up to the end of the drilled blasting hole for a quarry mine, and thus the blasting performance is improved. It greatly improves the blasting environment by allowing even blasting in one blasting operation without secondary crushing.

In addition, in the present invention, the wound explosive bag 10 for drilling blasting is unwound and inserted into the drilling blasting hole for the quarry tunnel, and the worker can easily check the inserted length, so the explosive is placed in the drilling blasting hole for the quarry tunnel. The convenience of placing work can be greatly increased and work time can be shortened.

It should be noted that the present invention is not limited to the above-described embodiments, but can be implemented with various changes without departing from the gist of the present invention, and these are included in the configuration of the present invention.
