Embodiment Construction

[0019] In order to make the above-mentioned features and advantages of the present invention more comprehensible, the following specific embodiments are described in detail with reference to the accompanying drawings.

[0020] Such as Figure 1~3 As shown, a convenient and movable underground ventilation structure includes a rubber airbag used to inflate and block the underground ventilation structure. The windless side of the rubber airbag is provided with a self-stabilizing frame fixed to the rock wall.

[0021] In the embodiment of the present invention, the rubber airbag includes an inflatable rubber 6, the outer ring of the inflatable rubber is connected to the rock wall, and the inner ring of the inflatable rubber is closed by a fixed non-alkali glass fiber cloth 7.

[0022] In the embodiment of the present invention, the non-alkali glass fiber cloth is adhered to the inner ring of the inflatable rubber via Velcro.

[0023] In an embodiment of the present invention, the...

Abstract

The invention relates to a convenient and efficient movable underground ventilation structure. The underground ventilation structure comprises a rubber air bag used for inflating and blocking an underground ventilation structure body, and a self-stabilizing frame fixedly connected to a rock wall is arranged on the windless side of the rubber air bag. The underground ventilation structure has the beneficial effects of being capable of realizing rapid construction of the underground ventilation structure, good in seal performance, convenient to assemble and disassemble, capable of efficiently carrying out air flow temporary partition and air return roadway temporary blocking and capable of realizing dynamic adjustment of the air volume of an underground mine ventilation system.

Description

technical field [0001] The invention relates to a convenient and movable underground ventilation structure and a use method thereof, which are suitable for the fields of ventilation air volume control in underground mines, ventilation in underground mining areas, and the like. Background technique [0002] Mine ventilation system, as an important part of the eight major systems of ore mining in metal mines, plays a very important role in maintaining underground production safety. In the complex and changeable dynamic underground mine environment, how to set up ventilation structures through safe and convenient means to ensure the stable supply of air volume at the working face, and to minimize the energy consumption of the entire ventilation network on the premise of this is mine ventilation. key issues of the system. The environment of the underground working surface and the wind-demanding end is constantly changing, so a matching ventilation scheme is required for differe...
