A mobile adjustable blasting shelter device

Abstract

The invention relates to the technical field of mine protection shelters, in particular to a mobile adjustable blasting shelter device, which includes a shelter main body, the bottom of the shelter main body is welded to the top of the middle section of a supporting guide assembly, and the supporting guide assembly is used for Realize moving and unloading force after being impacted. The main body of the bunker is made of alloy steel. There is a main grip ring welded on it. It can effectively provide safety protection for the current staff, and the protection is good. After being severely impacted by sand and gravel, the device can move to reduce the impact force of sand and gravel, and the front end of the bunker is designed with an arc-shaped spherical metal structure, which can Effectively improve the protection against sand and gravel, the staff can effectively grasp the bunker inside the bunker, and improve the stability of the staff inside.

Description

technical field [0001] The invention relates to the technical field of mine protection shelters, in particular to a mobile adjustable blasting shelter device. Background technique [0002] In the process of underground coal mining, if hard rocks are encountered and the fully-mechanized excavator cannot dig, it is necessary to fire blasts to continue excavation and mining. Generally, blasting is required under the following working conditions in the process of coal mining. and blasting mining treatment: 1. blasting mining face; 2. blasting roadway; 3. renovation of roadway with special structure; The coal seam layout roadway encounters fault rocks, and the cutting head of the roadheader is not damaged, and the rock excavation method is also used. The coal mine needs to build special structures (coal bunkers) or small roadways. [0003] In summary, blast mining is a relatively important mining method in the process of underground mining. Due to the particularity of the underg...

Problems solved by technology

[0003] In summary, blast mining is a relatively important mining method in the process of underground mining. Due to the particularity of the underground environment and the ground conditions, strong vibrations in the process of blast mining will cause sand and gravel to splash around. , In a few cases, there will be a large test block flying down, so when the staff is performing blasting in the working environment, there will still be accidents of flying stones hurting people outside the safe distance, especially when the inspectors are inspecting forward. Considering the safety hazards of underground construction, the staff of our mine designed a mobile adjustable blasting bunker after a long period of practice and research to solve the existing safety hazards.
