Research And Implementation Of Coalmine Ventilation Network Calculation Software

Mine ventilation is an important part of the production underground. A safe, reliable, economic and practical coalmine ventilation network calculation software is important to guarantee the safety in production underground. Thus the research and implementation of coalmine ventilation network modeling and calculation is given in the paper.Based on Fluid Network Theory and some experience formulas, the flow resistance model is built. It calculates the resistance factors by using the design parameters of laneways instead of manual experiments. Introducing the reelect loop to Scott-Hinsley arithmetic accelerates the ventilation network calculation on the built model. Using MATLAB and Visual C++, the software is developed. It can not only work by itself, but also work as a subsystem with Coalmine Integration Prevention Management System by the way of sharing the database.The Coalmine Ventilation Network Calculation Software can not only provide the information of ventilation volume distribution and regulating for the safety in production underground, but also provide real-time, actual and exact data and the information of correlative devices for the decision-makers of coalmine production departments in daily production. And it can monitor the abnormal situation such as gas density limited over by combing with the Coalmine Gas Accident Integration Prevention Management System to prevent the production accident and guarantee the security of workers underground.
