Description

Technical Field

[0001] This utility model relates to the field of coal mining technology, specifically to a precision blasting device for rock strata in open-pit coal mines. Background Technology

[0002] With the changing width and depth of mining operations and the diverse terrain features of mining areas, single-type, traditional blasting technologies are no longer sufficient to meet the requirements of schedule, quality, and safety. There is an urgent need to develop innovative blasting technologies to improve crushing quality and increase the variety of blasting materials to ensure the safe and stable operation of mines. Currently, most mines still rely on traditional blasting methods, which are cumbersome and fail to achieve high efficiency and low pollution.

[0003] In response, Chinese Patent Application Publication No. CN221685335U discloses an open-pit coal mine rock blasting device, including a moving device and a blasting device body. The placement component includes a second fixed plate, a rotating rod movably sleeved on the inner side of the second fixed plate, an I-beam wheel fixedly sleeved on the middle of the outer side of the rotating rod, a driven wheel fixedly connected to the left side of the rotating rod, a transmission belt provided on the outer side of the driven wheel, and lifting ropes fixedly connected to both sides of the outer side of the I-beam wheel. With the placement component and the fixed component, when the drive motor is started, the two conical support frames move away from each other. The bottom of the blasting device body slides downward along the inner side of the conical support frame, and when the threaded rod rotates, it drives the driving wheel to rotate, thereby the I-beam wheel unwinds the lifting ropes, so that the blasting device body can continue to move downward, pass through the positioning hole and enter the interior of the blasting hole, completing the stable placement of the blasting device body.

[0004] However, existing precision blasting devices for open-pit coal mine strata require drilling into the rock strata first during the blasting process. Since the existing devices cannot adjust the angle of the drill rod as needed, they are not suitable for various environments, thus increasing the limitations of the devices.
