Dry Air Shaft Seal Coal Mine Explosion-proof Equipment Research And Legislation

Ventilation system is one of the six systems of coal production. Vertical air shaft explosion-proof equipment is mine ventilation systems essential part. When a gas explosion in a coal mine and other dangerous situations, can play a protective fan, ventilation system to prevent the destruction of the role. For coal mine production safety and disaster relief are of great significance.In some cases investigated existing air shaft explosion-proof equipment at work use exist, and when combined with on-site personnel for the air shaft explosion-proof equipment using the problems of response, combined with mechanical design, materials, mechanics and other disciplines theory, research and design a new air shaft explosionproof equipment, to solve the existing vertical wind well sealed and reset problem, reducing the difficulty of air shaft explosion-proof equipment operational problems, reducing the number of staff to use.In this paper, the opposition air shaft explosion-proof equipment, structural design, stress analysis of a comprehensive exposition. Firstly, data query, data statistics obtained the relevant design data air shaft explosion-proof equipment. Design data obtained sequentially according to the structure of the lid opposing air shaft explosionproof equipment, seals, weight structure, the anti-wind device design. And uses the theory of classical mechanics, the force of the organization problem analysis and calculation, the structure correction several times, to ensure safe and reliable design.After completing the design of the structure, using three-dimensional modeling design methods now, were established three-dimensional model of each part of the device, and assembled using three-dimensional design software analysis to find out the interference, ensure that the design is reasonable, while reducing equipment research costs.Finally, the use of computer software, equipment of dynamics, stress and deformation for more precise analysis, and structural design is reasonable to verify this.
