摘　　要：矿井通风是保障矿井安全的主要技术手段之一。以孟村煤矿通风系统为工程背景,对原有的通风系统进行综合分析,提出现场通风方案存在的问题,并对提出的优化改造方案进行模拟对比。结果表明,利用ObjectARX技术建立的通风系统三维模型,模拟结果与现场测定数据误差小于10%,模型及相关参数具有可靠性。根据现存矿井通风系统问题,提出二号回风立井井底贯通、中央回风大巷功能优化、二号回风立井主通风机未启动前安装调节风门等3条措施。根据这3条改进措施,对改造后的通风系统进行模拟计算,得出应用优化措施后主、副井底进风大巷及403盘区一号回风大巷通风能力能够满足过风要求;二号回风立井投运后,中央一、二号辅助运输巷、中央胶带巷和二号水仓西部联络巷风速分别为6.4 m/s、4.0 m/s、3.3 m/s、3.8 m/s,403盘区一号回风大巷最大风速约5.5 m/s,表明该优化改造措施方案可有效解决孟村煤矿通风系统存在的问题,实现通风系统的合理配置。Mine ventilation is one of the main technical means to ensure mine safety.Taking the ventilation system of Mengcun Coal Mine as the engineering background,the original ventilation system is comprehensively analyzed,and the problems existing in the on-site ventilation scheme are put forward.The corresponding optimization and transformation scheme is proposed,and the simulation comparison is carried out.The results show that the three-dimensional model of ventilation system can be established based on ObjectARX technology.The error between the simulation results and the field measurement data is less than 10%,and the model and related parameters are reliable.According to the existing problems of mine ventilation system,three measures are put forward,such as the bottom penetration of No.2 return air shaft,the function optimization of central return air roadway,and the installation of air-regulating door before the main fan of No.2 return air shaft is not started.According to the three improvement measures,the ventilation system after the transformation is simulated and calculated.After the optimization measures are applied,the ventilation capacity of the main and auxiliary shaft bottom air-entering roadway and the No.1 return air roadway in the 403 panel meets the requirements of wind passing.After the No.2 return air shaft is put into operation,the wind speed of the central No.1 and No.2 auxiliary transportation roadways,the central belt roadway and the western contact roadway of the No.2 sump are 6.4 m/s,4.0 m/s,3.3 m/s and 3.8 m/s,respectively.The maximum wind speed of the No.1 return air roadway in the 403 panel is about 5.5 m/s.The existing problems with the ventilation system is effectively solved by implementation of the optimized scheme,realizing the reasonable configuration of the ventilation system.
