【摘要】：鲁班山南矿主要通风机的理论特性曲线和实际特性曲线存在很大的差别,另外矿井通风设计提供的风量比实际用风量小、而矿井设计通风风阻比实际矿井通风风阻大,致使目前该矿主通风机工况点处在明显不合理的位置:风机已经没有富裕能力、效率低下。先从优化通风线路入手,提出3个通风方案,并利用通风网络解算软件对其中2个可行的方案进行了通风网络解算;从通风网络解算结果和其他几方面的定性比较,得出了最优方案,即"三进一回"的通风方案。结合选定的最优矿井通风方案,再从矿井主要通风机运行的技术可行性、运行成本和投资成本考虑,提出了首先对现有的2台对旋防爆轴流式主要通风机进行技术改造,更换主要通风机风机叶片、更换电机等,后期结合第二水平的通风改造,更换通风能力更大的主要通风机。
[Abstract]:There is great difference between the theoretical characteristic curve and the actual characteristic curve of the main ventilator in Luban Shannan Mine. In addition, the air volume provided by the mine ventilation design is smaller than the actual air volume, and the mine design ventilation air resistance is larger than the actual mine ventilation air resistance. As a result, the operating point of the mine main fan is obviously unreasonable: the fan has no rich ability and low efficiency. Starting with the optimization of ventilation lines, three ventilation schemes are put forward, and two feasible ventilation schemes are calculated by using ventilation network solution software, and the results of ventilation network calculation are compared qualitatively with those of other aspects. The optimal scheme, that is, the ventilation scheme of "three times into one cycle", is obtained. Considering the technical feasibility, operation cost and investment cost of the main ventilator in the mine, combined with the optimal mine ventilation scheme, this paper puts forward the technical transformation of the two main axial flow fans for anti-explosion. The main fan blade is replaced, the motor is replaced, and the main ventilator with greater ventilation capacity is replaced in the later stage combined with the second level ventilation reform.
