Research Of Ventilation Scheme Of Coal And Gangues Separating Workshop In The Changcun Mine Well Bottom

In the process of our coal mining can produce a large number of coal gangue, establishment of Bottom hole gangue workshop. The coal gangue are filled to underground, can effectively solve the problem of inefficient transportation and ground washing caused the resource waste and environmental pollution. This thesis for the ventilation system scheme of research of Changcun coal mine bottom hole gangue workshop, effectively guarantee the workshop is stable and reliable.This thesis analyzes the existing ventilation system of Changcun coal mine, it is aimed at the ventilation system of Changcun coal bottom choose bottles workshop. Using FLUNT to simulation air flow of Bottom choose bottles workshop, through flow field observe whether air volume is enough, so as to prevent the occurrence of the breeze, eddy current phenomenon. At the same time, according to the ventilation system of Changcun coal mine characteristic, make proposed the ventilation system optimization scheme, by using ventilation system software for simulation, analysis the results of simulation, and specific analysis of ventilation system of air distribution, pressure distribution, determined the return air system, ensure workshop has enough air volume, the workshop can safe operation. The thesis describe the study and design of mine ventilation system optimization, according to the mine ventilation system design principles and the actual need, after careful analysis and study, make sure the best plan to meet the need of actual production.This thesis combination of theory and practice of implements to bottles workshop ventilation system optimization, the study is great of significance to the actual production needs.
