Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mine exploitation, and in particular to an intelligent charging device for open-pit mine rock perforation blasting and a charging method. BACKGROUND

[0002] Blasting operation is an important link in the production process of a mine. Among them, blasting charging is an important production link of open-pit mine exploitation, and the charging effect directly affects the production efficiency and production cost of the mine. Related scholars have studied the vibration of continuous charging and interval charging by numerical simulation; and proposed that the hoisting air interval charging technology be applied in deep hole bench blasting, thereby effectively improving the blasting effect. Although there are many theoretical studies on blasting charging, due to the complexity and diversity of the mine rock mass and working conditions, there is currently no complete construction system and device that can well solve such problems.

[0003] Mine blasting is a technology that uses explosives to produce compression, loosening, destruction, throwing and killing effects in air, water, soil and rock medium or object to achieve the desired purpose. When the explosive charge explodes in the soil and rock medium or structure, the soil and rock medium or structure will produce compression, deformation, destruction, loosening and throwing, mainly used for earthwork engineering, and demolition of metal buildings and structures.

[0004] According to the search, the publication (announcement) number: CN218723582U discloses a charging device for coal mine underground deep hole blasting, the whole device is pushed to the upper part of the blast hole position through the roller, the barrel door is opened, the explosive package is placed on the baffle inside the charging barrel, the charging barrel is placed along the blast hole position, the rotating shaft is rotated in the first cavity by rotating the rocker, and the reel is rotated at the same time. During the rotation process, the lifting rope wound outside the reel is released. Since one end of the lifting rope passes through the hole and is connected with the lifting rings on both sides of the charging barrel, the released lifting rope will enter the deep part of the blast hole along with the charging barrel. When reaching the specified depth, the rotation of the screw rod driven by the output end of the micro motor causes the first slide to slide downward along the screw rod. While the first slide slides downward, the two ends of the first slide deflect the baffle downward through the second connecting rod, and at the same time, the first slide slides upward along the screw rod. The two ends of the first slide deflect the bottom plate upward through the first connecting rod, thereby opening the bottom of the charging barrel. When the baffle and the bottom plate are completely retracted, the explosive will slide out of the inside of the charging barrel along the inner wall and enter the deep part of the blast hole. The charging barrel is pulled out of the deep part of the blast hole by reversing the rocker, and then the charging barrel is recycled to complete the charging.

[0005] However, in actual engineering, the charging effect depends on the drilling effect and the hole forming rate. Because the drilling is not a smooth platform under the ideal model, it is restricted by different geology, hydrology, drilling conditions, etc., and the hole forming state is different, which leads to the difficulty of standardization of charging. In addition, in the above-mentioned prior art, no buffer structure is provided, and a large impact force may be generated during movement, which will be directly transmitted to the roller and related parts, and may cause damage to the roller, bearing, transmission device, etc. over a long period of time, thereby shortening the service life of the equipment.

[0006] Therefore, we propose an open-pit mine rock perforation blasting intelligent charging device and charging method which can adapt to different working conditions. Based on the self-adaptive adjustment module, semi-automatic charging can be realized under different mine conditions, so as to optimize the rapid charging structure and effectively improve the blasting quality of the current coal mine.
