Abstract
Description
Technical Field
[0001] The invention relates to the technical field of solitary rock explosion prevention in rock blasting engineering, in particular to a solitary rock explosion prevention protection device. Background Art
[0002] With the continuous expansion of urban construction, rock blasting projects are common. Rock blasting projects are categorized as soft rock, medium-hard rock, hard rock, and very hard rock. The reduction of large boulders is even more frequent, making the control of flyrock hazards particularly important. Conventional rock blasting generally employs multiple layers of covering for these four types of rock, using heavy coverings and light coverings to protect against crushed rock, in accordance with blasting safety regulations. This layer-by-layer absorption of the blasting force prevents flying rocks, dust, and disperses the blasting shockwave.
[0003] Prior art methods for protecting against boulder explosions commonly employ rubber quilts, protective nets, bamboo nets, sandbags, protective barriers, and blast shelters. These cover the blastholes with multiple layers of material, effectively absorbing and dispersing the blasting shockwave to prevent flying rocks and dust during the detonation process. Watering is then used to reduce toxic blast smoke and dust after the blast. However, due to the high cost of preparing these materials and the complex procedures, safety controls during the blasting process are inconsistent, making it difficult to effectively control flying rocks, dust, and toxic blast smoke. This can easily lead to flying rocks injuring people and damaging structures, while toxic blast smoke harms the atmosphere and increases the risk of boulder explosions. Summary of the Invention
