Description

Technical Field

[0001] This utility model relates to the field of safety protection technology for underground mining operations, specifically a safety protection device for underground mining operations. Background Technology

[0002] Safety protection devices for underground mining operations are designed to protect the safety of miners working underground. They should comprehensively consider various hazardous factors underground and provide corresponding protective measures.

[0003] When drilling into a rock wall underground, the drilling rig generates impact force, causing the rock wall to vibrate and resulting in falling debris. This debris poses a significant safety hazard to construction workers. Existing protective measures involve using safety helmets to protect against the debris, but these helmets cannot protect the entire body of the workers and therefore cannot meet the needs of users, thus having limitations.

[0004] The reason for this problem is that vibrations can destabilize the rock structure above or around the rock face, leading to falling debris. These debris vary in size, from tiny rock fragments to larger boulders, and can fall from heights at any time, posing a serious threat to the safety of construction workers. Furthermore, safety helmets cannot fully cover the workers' bodies, and the impact force from the debris can still be transmitted through the shoulders, back, or legs, causing indirect injury and reducing work efficiency. Therefore, we propose a safety protection device for underground mining operations to solve these problems. Utility Model Content
