Description

Technical Field

[0001] The utility model belongs to the field of blasting protection devices, and particularly relates to a protection device for mining blasting. Background Art

[0002] The protection devices for mining blasting are usually used to protect workers from the dust and broken stones generated during blasting. These devices are designed with structures that can effectively reduce the harm caused by the blasting fragments to workers during blasting.

[0003] When the existing protection devices are used for mine blasting, they often use a single wire mesh to block the broken stones generated during blasting. However, the huge impact force during blasting will cause some broken stones to break when they come into contact with the wire mesh, and the small fragments after breaking will cause harm to the workers hiding behind the wire mesh through the wire mesh. The single wire mesh is also difficult to block the broken stones falling from a height, and the integrated wire mesh often needs to be built manually during installation and use, which is not only very time-consuming and laborious but also can only be used within a certain range, and it is difficult to disassemble it for secondary use.

[0004] Therefore, aiming at the problem that the integrated protection structure of the above protection device is often difficult to be quickly installed according to different sites during mine blasting and the effect of its protection structure in blocking the broken stones generated during blasting is not good, a protection device for mining blasting is developed. By adding a slide rail limit installation structure, a double-layer protection structure, a high-altitude protection structure and a quick disassembly and assembly structure to the protection device, the convenience of the device during installation and use can be greatly improved, the effect of protecting workers during blasting can be enhanced, and its stability during use can also be improved.
