基于Ventsim软件在矿井通风系统优化中的应用
摘要：丰山铜矿现有的矿井通风系统为副井、斜坡道进风，南、北缘回风井回风的双对角式通风系统。由于矿山的边缘矿体一直没有顺利采完和及时密闭；随着东翼新矿体的发现和坑探等需要，矿山的开采顺序与原设计的产生了较大变化；矿床开采技术条件越来越差,造成矿井通风系统客观上满足不了实际生产的需要。
本文在查阅和分析国内外矿井通风的研究现状和发展趋势之后，通过现场调查与测定研究，指出了丰山铜矿矿井通风系统的存在问题，计算了丰山铜矿的自然风压及其变化规律，建立了丰山铜矿矿井通风系统的可视化模型，在此基础上从南缘和北缘通风系统优化改造提出了多个优选方案，通过技术可行性，经济可行性，并结合不同方案的通风特点进行比较、选优。对优选的方案进行数值模拟，获得各风机，各中段的风量分配情况，并实现可视化。经过比选后得出了丰山铜矿通风系统的优化改造方案。
本文研究综合采用矿井通风学、空气动力学、热力学、系统工程、优化理论等对丰山铜矿矿井通风系统进行优化研究，构建了三维矿井通风网络图。采用丰山铜矿各中段平面图以及相关工程的相关图纸、资料信息，利用Ventsim通风系统软件，可视化丰山铜矿矿井通风系统，有利于加深对通风系统的认识。
通过该项目的实施，可以整体优化全矿通风系统，确定通风系统关键参数，建立工作面风量和风质的控制体系，实现矿井通风系统稳定、高效和节能。

Ventsim based software application in the optimization of mine ventilation systemAbstract: existing in Fengshan copper mine auxiliary shaft of mine ventilation system, inlet slope wind, North and South Rim air shaft return double diagonal ventilation system. Due to the edge of the mine ore mining has been successfully finished and sealed in a timely manner; as the new East Wing orebody discoveries and needs such as pitting, mining the mining sequence and original designs have been changed; mining technical conditions getting worse, objectively caused by mine ventilation system can not meet the actual needs.Paper in check out and analysis both at home and abroad mine ventilation of research status and development trend zhihou, through site survey and determination research, pointed out that has Fengshan copper mine ventilation system of exists problem, calculation has Fengshan copper of natural wind pressure and changes law, established has Fengshan copper mine ventilation system of Visual of model, this based Shang from South margin and North margin ventilation system optimization transformation proposed has multiple optimization programme, through technology feasibility, economic feasibility, and combined different programme of ventilation features for compared, and selection. Numerical simulation of optimal programmes, access to the fan, the air flow distribution in the Middle, and visualization. After a selection obtained in Fengshan copper mine ventilation system optimization transformation programme.Based research on comprehensive mine ventilation, aerodynamics, thermodynamics, systems engineering, optimization theory to optimization of mine ventilation system in Fengshan copper mine, built three dimensional mine ventilation network graph. The middle section of the plane in Fengshan copper mine maps and information related to engineering drawings, data, using Ventsim ventilation system software, visualization of mine ventilation system in Fengshan copper mine, is conducive to deepening understanding of the ventilation system.Through its implementation, optimization of mine ventilation system as a whole, determine key parameters of the ventilation system, establishment of working face air volume and air quality control system to achieve stability, high efficiency and energy-saving of mine ventilation system.Key words: ventilation system edge ore body; natural wind pressure of numerical simulation of air distribution and ventilation network control systemClassification number: TD72

On the basis of Ventsim software in the optimization of mine ventilation system application
Abstract: Feng Shan copper existing mine ventilation system for auxiliary shaft and ramp into the wind, in the southern and Northern margins of return air shaft double diagonal ventilation system. Because the ore body of the mine has been closed and sealed in time, the mining sequence and the original design of the mine have been changed greatly, and the technical conditions of the ore deposit are getting worse. In this paper, the research status and development trend of the domestic and foreign mine ventilation are analyzed,Through field investigation and determination of pointed out in Fengshan Copper Mine ventilation system problems calculated Feng Shan copper mine, natural wind pressure and its variation, the visualization model of Fengshan Copper Mine ventilation system is established, on this basis from the southern and Northern margins of the ventilation system optimization and transformation proposed multiple optimal solutions, through technical feasibility, economic feasibility, and combined with the ventilation characteristics of different schemes were compared and the optimal selection. Numerical simulation is carried out to obtain the distribution of air flow in the middle section of the wind turbine, and realize visualization. After the selection, the optimization of ventilation system of the Feng Shan copper mine is obtained.
In this paper, the optimization of mine ventilation system in the mine ventilation system is optimized by using the mine ventilation system, air dynamics, thermodynamics, system engineering and optimization theory. The use of Ventsim ventilation system software and the visualization of the mine ventilation system is helpful to deepen the understanding of the ventilation system.
through the implementation of the project, overall optimization, mine ventilation system, determine the key parameters of the ventilation system, establish a working face of air volume and air quality control system, to realize the mine ventilation system stability,High efficiency and energy saving.
