Underground roadway blasting shielding device

Abstract

The invention discloses an underground roadway blasting shielding device. The underground roadway blasting shielding device comprises a water storage device placed behind a blasting device, wherein screens are arranged on the two sides of the bottom of the water storage device; the water storage device releases water flow in the blasting process to form a water screen with the screens; and the screens are retracted and released by a screen retracting and releasing device. According to the underground roadway blasting shielding device, damage caused by shock waves in the blasting process is reduced in the mode that water absorbs the blasting shock waves, a blasting mode needs to be adopted for tunneling for rocks in a roadway, the shock waves radiated outwards in the blasting process are absorbed in the mode that the water flow is added between two screens, harm caused by the shock waves in the blasting process is reduced, the safety of the blasting tunneling process is improved, and meanwhile, pollution to a construction site due to blasting impact and damage to the mechanical device under the action of the shock waves are avoided; and the water screen effectively isolates a blasting working environment from working environments of other underground positions, impact and dust caused by blasting work are avoided, and the reliability of underground work is improved.

Description

technical field [0001] The invention belongs to the technical field of coal mining, in particular to an underground roadway blasting shielding device. Background technique [0002] At present, my country has large coal reserves and high output. At the same time, coal is the most important part of my country's energy structure. It is of great significance to study coal mining methods. my country's coal mining methods are large, but they are widely used and adaptable. The blasting method is still the blasting method. The blasting method needs to blast the coal mine. This work process will produce a large impact damage, which will cause damage to the fully mechanized mining equipment and even pose a threat to the life and health of personnel. The huge shock wave may also have an impact on the ground. Therefore, it is necessary to study a reliable method that can absorb or reasonably release the shock wave during the blasting process, so as to effectively reduce the blasting shock...

[0002] At present, my country has large coal reserves and high output. At the same time, coal is the most important part of my country's energy structure. It is of great significance to study coal mining methods. my country's coal mining methods are large, but they are widely used and adaptable. The blasting method is still the blasting method. The blasting method needs to blast the coal mine. This work process will produce a large impact damage, which will cause damage to the fully mechanized mining equipment and even pose a threat to the life and health of personnel. The huge shock wave may also have an impact on the ground. Therefore, it is necessary to study a reliable method that can absorb or reasonably release the shock wave during the blasting process, so as to effectively reduce the blasting shock and ensure the safety and reliability of coal mining.
