AI Technical Summary
Existing drilling rigs are difficult to move in narrow coal seam mining spaces, have high technical barriers to operation, and require a high level of experience from operators.
A drilling device for fracturing the roof of a coal mine working face was designed, comprising a supporting hydraulic cylinder, a lifting seat, a rotating mechanism, and moving wheels. The device's movement and drilling are achieved through hydraulic control, reducing the difficulty of operation.
It enables convenient movement and drilling in narrow coal seam mining spaces, reduces the experience requirements of operators, and improves the flexibility and ease of operation of the equipment.
