【摘要】 完善、可靠的通风系统是做好矿井“一通三防”的基础,是保证矿井安全生产的重要前提。构建合理的通风系统,为有效预防瓦斯、火灾等事故的发生提供安全保障；同时,对提升矿井的抗灾变能力都具有重要的现实意义。本文通过对阳煤五矿通风系统进行了系统地普查,在对相关参数进行详实测试基础上对测试数据进行相应的技术分析与处理,构造阳煤五矿矿井通风智能管理系统,建立通风系真模拟模型,利用软件对进行解算和分析,矿井南翼采区有如下问题：进风区段阻力偏大、通风构筑设置偏多、巷道局部地点风阻偏大和进、回风井相互制约明显等主要问题。通过通风系统方案对比分析和优化调整,提出科学合理的通风系统技术改造方案。当2#主斜井进风量在168m3/min-2500m3/min之间时,南翼运输巷局部地点风量小。未达到降阻目的,确定了对520水平南翼运输副巷改道,增大2#主斜井风量。结果表明：520水平南翼运输改道62m,当2#主斜井进风量2486m3/min时,可达南翼采区降阻幅度达466Pa,其它各巷道风速达标。调整改造方案简单可行、满足生产要求,有效地降低了阳泉五矿南翼通风阻力,取得了良好的经济效益。更多还原

【Abstract】 Perfect and reliable ventilation system is an important basis to do well "one ventilation and three prevention" of mine, and an important premise to ensure the safety production of coal mine. It can provide the safety guarantee for preventing gas and fire accidents by constructing a reasonable ventilation system. Simultaneously, it also has important practical significance for improving the mine ventilation system’s ability of resisting natural disasters.In this paper, through carrying on the systematical surveys to Yangquan No.5 coal mine, the tested data were technically analyzed and processed based on the detailed measurement, and the intelligent management system of ventilation was constructed for Yangquan No.S coal mine. The simulation model of mine ventilation system was established for Yangquan No.5 coal mine. The mine ventilation system was calculated and analyzed by utilizing the intelligent management system software of mine ventilation. The simulated results showed that the main problems of ventilation system currently existing in south mining area had large resistance in the wind inlet section, more ventilation buildings, larger ventilation resistance in local place of roadway and restricted obviously each other between the intake and return shaft. By comparing analysis and optimization adjustment of the ventilation system scheme, based on the comprehensive analysis and study of various factors, the scientific and reasonable technical transformation scheme of mine ventilation system was put forward. There was gentle breeze at local place of North haulage roadway while the intake air quantity of 2# inclined shaft was 168m3/min-2500m3/min. Based on the comprehensive testing and simulated results, the north haulage assistant roadway at 520 level would be re-channeled to increase the intake air quantity of 2# main inclined shaft and decrease the ventilation resistance of North mining area. The results showed that the ventilation resistance in north mining area would reduce 466Pa and the air velocities of other roadways reached the standard of Mine Safety Regulation while the intake air quantity of 2# main inclined shaft was 2486m3/min by re-channeling 62m north haulage assistant roadway at 520 level. After implementing the optimal scheme, the effect of reducing resistance was obvious and the measured air quantity of main roadways were basically anatomist to simulated data. The adjustment and alteration scheme was easy and feasible, and meted the production requirement. It not only effectively reduced the ventilation resistance of Yangquan No.5 coal mine, but also improved ventilation condition of north district. And the good economic and social benefits were obtained.更多还原
