Description

Technical Field

[0001] The utility model relates to the technical field of mining equipment, in particular to a blasthole blocking device for an open-pit mine. Background Art

[0002] After the drilling is completed at the open-air operation site, it is necessary to carry out processes such as hole measurement, rock powder sampling and testing, and blasting planning. If the blasthole is not sealed during this process, rock powder will slide into the hole, surface water will flow into the hole, and the hole mouth and hole wall will collapse, affecting the later blasting effect. Therefore, the blasthole sealing directly determines whether the later hole measurement, hole cleaning, and charge have an effective blasthole depth. At present, bagged rock powder is mostly used for blasthole sealing. This sealing method has the problems of cumbersome operation, rock powder sliding into the hole, and damage to the hole mouth during construction. Moreover, this sealing method does not have the function of measuring the hole depth, and the measuring hole needs to be opened multiple times, which increases the probability of rock powder entering the blasthole; after the blasthole construction is completed, there will be water seepage in the blasthole and the hole wall will collapse. The current sealing method cannot effectively reflect these situations.

[0003] To this end, it is necessary to study a device that is convenient for sealing blastholes, which is conducive to on-site hole depth measurement and water seepage reaction, so that the blasthole operation and subsequent processes can be connected in an orderly manner and the situation of the on-site blastholes can be better controlled.

DETAILED DESCRIPTION

[0014] In order to make the technical problems and technical solutions solved by the utility model more clearly understood, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0015] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0016] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0017] like Figures 1 to 4 As shown, a device for plugging blastholes in an open-pit mine includes a plugging plate 1, the diameter of the plugging plate 1 is larger than the aperture of the blasthole, a handle 2 is connected to the top of the plugging plate 1, and a circular protective wall 3 is connected to the bottom, and the circumferential contour of the circular protective wall 3 matches the aperture of the blasthole. When plugging the blasthole, the circular protective wall 3 is inserted into the blasthole, the circumferential wall of the circular protective wall 3 will fit with the inner wall of the blasthole, and the plugging plate 1 covers the blasthole mouth, thus completing the plugging of the blasthole, which is convenient and quick.

[0018] In order to improve the plugging effect, the circular protective wall 3 is designed to be divided into two parts, the upper part is a rigid protective wall 31, and the lower part is a flexible protective wall 32. The rigid protective wall 31 can provide a strong support effect, and after plugging, it can prevent equipment operation and personnel activities from damaging the blast hole mouth, and protect the hole wall for a long time; the flexible protective wall 32 has a flexible characteristic, and when the plugging device is installed, it can prevent it from contacting and damaging the blast hole mouth.

[0019] In order to measure the depth of the blasthole and understand the situation of the blasthole after the blasthole is blocked, a borehole rope 4 is provided at the center of the blocking plate 1. One end of the borehole rope 4 passes through the counting device 5 and is wound around the measuring rope transceiver 6. The counting device 5 and the measuring rope transceiver 6 are arranged on the upper surface of the blocking plate 1. The counting device 5 also includes a counting display 51 that can display the length of the measuring rope being lowered and a measuring rope switch 52 that controls the lowering or stopping of the measuring rope. The counting device 5 and the measuring rope transceiver 6 can be used in conjunction with an existing meter counter and a winder. The other end of the borehole rope 4 is connected to a borehole ball 7. A buoyancy layer 8 is adhered to the outer surface of the borehole ball 7. The borehole ball 7 has a certain deadweight that can provide a certain gravity for the lowering of the borehole rope, and the buoyancy layer 8 can make the borehole ball 7 float on the water surface when the borehole ball 7 encounters water.

[0020] After the blasthole is sealed, the measuring rope switch 52 is pressed, and the measuring rope 4 is lowered under the gravity of the measuring ball 7 until the measuring ball 7 falls to the bottom of the hole, and the counting display 51 will display the actual hole depth. When the blasthole is seeping and water is accumulated, the measuring ball 7 floats on the water surface under the action of the buoyancy layer 8, and the measuring rope transceiver 6 recovers the measuring rope 4 (the measuring rope transceiver 6 can cooperate with the sensor to automatically retract and release the measuring rope according to the change of the pulling force), correct the actual hole depth, and the counting device 5 records the recovered data, and the counting display 51 displays the latest data; when the hole wall collapses, the rock presses down the measuring rope 4, which will cause the counting display 51 to display abnormal data, which can prompt the staff.

[0021] To sum up, the blasthole plugging device provided by the utility model has a simple structure and is easy to operate. It can quickly and effectively seal the blasthole and reduce the damage to the blasthole caused by the plugging device, thereby avoiding external rocks, rock powder, etc. from falling into the blasthole and increasing the cleaning work. It can also be disassembled and reused, thus reducing the cost of blasthole plugging. It is suitable for the plugging of open-air blastholes and other similar blastholes.

[0022] The plugging device can also accurately measure the actual depth of the blasthole in real time through the cooperation of the counting device, the measuring rope sending and receiving device and the buoyancy ball, and reflect the occurrence of water seepage in the blasthole, collapse of the hole wall, etc., which serves as a correction guide for the subsequent charging design, allowing the staff to know in advance whether the hole needs to be cleaned, repaired or other precautions are needed, ensuring the orderly connection between the blasthole operation and the subsequent process, shortening the process gap and improving the operation efficiency.

[0023] The present invention is described in detail above through specific and preferred embodiments, but those skilled in the art should understand that the present invention is not limited to the embodiments described above, and any modifications, equivalent substitutions, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
