Metal ore rapid sealing wind blocking device

Abstract

The invention discloses a metal ore rapid sealing wind blocking device. The device comprises a rapid assembling steel structure and a windshield cloth, wherein the quick assembling steel structure comprises a rectangular frame used for supporting the windshield cloth and a triangular support used for supporting the rectangular frame; the rectangular frame and the triangular support are both formedby connecting a plurality of rod bodies, wherein the rectangular frame is located in the plane where the section of a roadway is located, the triangular support is arranged at the leeward side of therectangular frame, and the plane where the triangular support is located is perpendicular to the section of the roadway; and the windshield cloth is arranged on the windward side of the rectangular frame, the edge of the windshield cloth is fixed with the wall surface of the roadway, and a zipper type air door is arranged at the position, close to the lower position, of the middle of the windshield cloth. According to the device, the structure is reasonable, the assembly and disassembly are easy, metal ore sealing wind blocking and temporary air distributing can be rapidly achieved, the roadway sealing efficiency is improved, the problem that a sealing monomer cannot be recycled is solved, and the sealing cost is greatly reduced.

Description

technical field [0001] The invention relates to the field of mine ventilation, in particular to a fast airtight air blocking device for metal mines. Background technique [0002] As an important part of metal mining, mine ventilation system plays an important role in mining. A good mine ventilation system is not only an economical and long-term system, but also can provide a good working environment for the workers in the mine. When a safety accident occurs, the ventilation system can also change the original wind direction, control the direction of the wind flow to a certain extent, and eliminate the occurrence of mine accidents to the greatest extent. However, there are still some problems in the ventilation system of metal mines in my country, mainly in the following aspects: [0003] A. So far, the open-pit mining method is still the most common mining method for metal mines. After adopting this method of mining, a large number of goafs were left by mining, but mining...

Problems solved by technology

These three methods are all good solutions, but the first two methods have high economic costs and need to be redesigned and installed on the basis of the original facilities, which is time-consuming and expensive. The third method is slightly simpler than the first two designs, but It is necessary to transport a large amount of construction materials underground, and the economic cost is also high, which is time-consuming and labor-intensive
