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 an oxygen-enriching device and method for a driving face in a high-altitude mine. pipeline mechanism; the method comprises the following steps: 1. installation of the regional oxygen supply mechanism; 2. connection of the oxygen supply nozzle mechanism; 3. activation of the regional oxygen supply mechanism; 4. activation of the oxygen supply nozzle mechanism; Oxygen-enriched area. In the present invention, the oxygen supply nozzle mechanism is set to pressurize and increase the oxygen in the local area near the mouth and nose of the operator, and at the same time, the oxygen gathering disc forms an annular air curtain and local oxygen enrichment in the area surrounded by the annular air curtain, so as to concentrate the oxygen in Oxygen is supplied in the breathing zone area around the workers and an air barrier is formed around the workers to slow down the diffusion and loss of oxygen, so as to achieve the purpose of increasing the oxygen content in the breathing zone of the workers, ensuring the safety of the workers and improving work efficiency.

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...
