A structure used for regional ventilation of underground mines and its construction method

Abstract

The invention relates to a structure used for ventilation in an underground mine area and a construction method thereof, comprising a skeleton arranged in a roadway and having an arc-shaped top plate on the top, and a force-giving device for supplying upward lifting force is arranged at the bottom of the skeleton. The front and rear sides of the arc-shaped roof are respectively provided with a plurality of wind-blocking cloths whose upper ends are detachably connected to the arc-shaped roof and whose lower ends hang down to the ground, and two adjacent wind-blocking cloths are connected by zippers. The structure is quick to install, which not only enhances the stability of the roadway, but also can withstand the blasting shock wave and block the wind flow.

Description

technical field [0001] The invention relates to a structure used for ventilation in an underground mine area and a construction method thereof. Background technique [0002] The mine ventilation structure is an air flow control facility in the mine ventilation system, which is used to ensure that the air flow flows according to the route required by production. A device for directing, blocking, and regulating air flow. At present, the structures that guide and control the passage of the wind flow and the structures that block the wind flow are mainly realized by building walls manually, but the labor cost of building the walls is relatively high, and the construction period is relatively long, usually 6 to 10 days; construction materials need to be obtained from the local The process of purchase and transportation is time-consuming and labor-intensive; not only the installation cost is high, but also the steps of building walls are cumbersome and expensive.

Problems solved by technology

At present, the structures that guide and control the passage of the wind flow and the structures that block the wind flow are mainly realized by building walls manually, but the labor cost of building the walls is relatively high, and the construction period is relatively long, usually 6 to 10 days; construction materials need to be obtained from the local Time-consuming and labor-intensive during purchase and transportation; not only the installation cost is high, but also the steps of building walls are cumbersome and expensive

At the same time, these structures are permanent structures, which cannot be disassembled and reused, which is not conducive to escape.
