Abstract
This article is based on the situation of too large coal mine ventilation resistance in the Majiagou coal mine. According to Majiagou coal mine late production plans, it measures resistance comprehensively, analyses the resistance distributions and the problems exist in the ventilation systems and comes up with targeted optimization programs. By studying the ventilation system model, as well as adjusting the system parameters, Ventsim software is applied to study ventilation system in Majiagou coal mine. Design of mine ventilation is proved practical in the mine ventilation system optimizations, thus Ventsim software can not only be used in the ventilation network calculation and merry-demand simulation and dynamic of wind flow, but also can be used to assist in the short-term and long-term planning for ventilation system, it is of a certain significance of guidance to find the problems in the mine management and optimizations of the ventilation network.
Highlights
Ventsim is based on independent platform mine ventilation implement software, the system has very good compatibility, 3-d model is generated by putting basis data from other mine design software or the ventilation software into the system conveniently
The real 3-D artwork technology is adopted by building a model, complicated mine ventilation process will be shown directly with 3-D by the consumers
After multiple communications and discussions with the field engineering and technical personnel, we put forward the two optimization scheme and simulate them as follow: 1) Scheme 1: Renovation project for all of conducted to wind eyes and 13 tunnels whose wind resistance is larger than others, ventilation ability is improved by expanding lane engineering and regulating system
Summary
Ventsim is based on independent platform mine ventilation implement software, the system has very good compatibility, 3-d model is generated by putting basis data from other mine design software or the ventilation software into the system conveniently. The real 3-D artwork technology is adopted by building a model, complicated mine ventilation process will be shown directly with 3-D by the consumers. By coloring different data in different colors, ventilation process key data and weak link are clear at a glance. By building 3-d ventilation system model , network ventilation is resolved and wind machine is selected preferably , thereby, ventilation effect is detected and controlled to satisfy the shaft design and management requests
