Problems solved by technology

This method has obvious defects: the oxygen produced by the oxygen cylinder or the oxygen generator reaches the vicinity of the personnel work area through the oxygen pipeline, and is restricted by the natural and artificial air flow in the work area, and the distribution is uneven, and it is easily polluted by mine dust and lost. serious

Abstract

The invention discloses a high-altitude mine driving face oxygen-enrichment device and method. The device comprises a regional oxygen supply mechanism which is arranged at the top of a tunnel and is matched with a driving face, an oxygen supply nozzle mechanism used for body wearing and an air-supply pipeline mechanism. The method comprises the following steps: 1, mounting of the regional oxygen supply mechanism; 2, connection of the oxygen supply nozzle mechanism; 3, start of the regional oxygen supply mechanism; 4, start of the oxygen supply nozzle mechanism; and 5, regional oxygen enrichment of a full-tunnel driving face. According to the high-altitude mine driving face oxygen-enrichment device, the local area close to the mouth and nose of an operator is subjected to pressure boostingand oxygen enrichment through the oxygen supply nozzle mechanism, an annular air curtain and local oxygen enrichment in the area enclosed by an annular air curtain can be formed through an oxygen enrichment disc, oxygen is concentrated in the respiratory zone area around the operator to supply oxygen and form an air barrier around the operator, and oxygen diffusion and loss can be retarded, so that the aims of increasing the content of oxygen in the respiratory zone of the operator, guaranteeing the life safety of the operator and improving the work efficiency can be achieved.

Description

technical field [0001] The invention belongs to the technical field of oxygen enrichment in mine excavation working face, and in particular relates to an oxygen enrichment device and method in high altitude mine excavation working face. Background technique [0002] At high altitudes between 1500m and 3500m, the air is thin and hypoxia is serious, and the driving face is the main working area of ​​high-altitude mines, and the oxygen content in this area is further reduced due to the oxygen consumption of blasting, equipment and personnel. In the special hypoxic working environment, the health and life safety of workers are facing severe challenges. Under the special conditions of the plateau, the oxygen generator is used to supply oxygen. The mine environment with low air pressure, low oxygen partial pressure and low temperature has higher technical requirements for the oxygen generator, which greatly increases the cost of oxygen supply; the use of oxygen cylinders for oxyge...
