Embodiment Construction

[0022] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0023] Combine now figure 1 , figure 2 , image 3 , Figure 4 As an example: first, at the place where a closed wall needs to be built, the top plate 1, the bottom plate 3 and the two roadway walls 7 are cut, and then the wooden wall 2 is built behind the construction roadway, covered with plastic film, and the roadway is closed to prevent slurry leakage. The construction site is selected in a roadway with a certain inclination angle and an inclination; the depth of the cut is 300-500cm, and the plank wall 2 is 20-30cm wide and 2-3cm thick red pine nails.

[0024] Four anchor rods 4 are placed at the top plate 1, the bottom plate 3, and the two roadway walls 7 in the middle of the construction airtight wall, which are square, such as Figure 4 As shown, do bolt hole 9 on the bolt, the bolt 4 of top plate 1 and ba...

Abstract

The invention relates to the technical field of mining security, and particularly relates to a method for constructing a mining impact-resisting sealed wall. The method adopts simpler and more convenient construction procedures, and light foam concrete is filled, so that the wall has the advantages of light weight, large bearing ability, strong flexibility, fire resistance and the like. The method is simple and convenient to construct, rapid in construction speed, good in construction effect; and the sealed wall has the advantages of good impermeability and good impact-resistance and fire-resistance.

Description

technical field [0001] The invention relates to the technical field of coal mine safety, in particular to a construction method for a mine anti-shock airtight wall. Background technique [0002] The disadvantages of the traditional brick-built concrete airtight wall are that the construction speed is slow and the labor intensity of the workers is high. Due to its own brittleness, when the pressure on the roof of the roadway is high, it is easy to cause cracks in the airtight wall and release gas and other toxic gases. When a rock burst occurs, the airtight wall will even be broken through, and concrete blocks will be ejected, causing damage to nearby workers and equipment, and endangering the safety of coal mine production. [0003] The disadvantages of the closed wall construction method of "spraying foam on the board wall" are that the thickness of the closed wall is thin, the amount of air leakage is large, and it is not strong, and even affects the daily ventilation work...
