Optimization Research For Ventilation System Of Chaohua Coal Mining Group

Ventilation system is one of the major systems in coal mine production, mine ventilation system can prevent many disasters, so rational arrangement of mine ventilation system is an important guarantee for mine safety. With the extension of deep level underground mining, mine air routes for the growing need to continue to increase air flow, resulting in increasing resistance to ventilation. Existing ventilation system can not meet production needs. Therefore, the optimization of mine ventilation system can protect the mine's safety, has an important means for efficient production,and has an important practical significance.In this paper,we researched the ventilation system's problems of Zhengzhou Coal Industry (Group) Co., Ltd. Chaohua. Mine. In this paper, the main mine fan, entilation and resistance were measured, and the measured data was analysised. We get the main problems of the mine ventilation system currently. Through the establishment of the mine ventilation network model and the computer network solutions, we analysis the ventilation system; according to which the actual situation, propose solutions to a variety of programs the mine ventilation problems, and computer programs for solving ventilation network. According to the actual situation of the mine, we propose a variety of programs which can resolve the mine ventilation problems, and we solve the ventilation network of the program by using computer. By analysing the calculating results, we can make sure if the program solve the mine problem; Finally, various options are optimized, and get the optimal solution which can resolve the problem of mine ventilation system about Chaohua. Mine.Through this study, we can resolve shortage of mine air flow, the resistance increases and other issues which form mine transformation and the developing of new level. This research has the most significance for the management of mine ventilation system.
