三山岛金矿新立分矿斜坡道通风系统优化

以三山岛金矿新立分矿斜坡道通风系统为研究对象，针对其存在的斜坡道能见度低、炮烟矿尘积聚、湿度大以及各个中段联巷风流紊乱等问题，运用通风网络优化技术以及风机优选技术展开了系统研究，提出采用强制通风方式将矿山主竖井、措施井的新鲜风流从-240 m中段东北巷引入斜坡道的通风模式，并采用Ventsim三维通风动态仿真模拟软件进行了解算。结果表明：通过优化井下东、西两翼回风路线，在67#线运输巷增设1台K45-6-№16型风机后，斜坡道进风量由15.03 m3/s提高至50.12m3/s，-320，-360，-400，-440，-480 m中段斜坡道联巷的进风量分别为11.33，11.21，11.15，11.09，11.01 m3/s，理顺了斜坡道通风系统，斜联巷风流紊乱现象得到有效改善，为矿山安全生产提供了技术支撑。

Optimization of the Ramp Ventilation System of Xinli Mine Shaft of Sanshandao Gold Mine

Taking the ramp ventilation system of Xinli Mine Shaft of Sanshandao Gold Mine as the study example,aming at the existing problems of low visibility of ramp,accumulation of gun smoke and dust,high humidity and ventilation disorder of connection roadways of middle sections of Xinli Mine Shaft,the ventilation system of Xinli Mine Shaft is studied systematically by using ventilation network optimization technique and fan optimization selection technique,the new ventilation model that is fresh wind from main shafts and measures shafts is imported to the ramp through the -240 m level northwest roadway by adopting the forces ventilation technique,besides that,the ventilation calculation is done by using Ventsim three-dimensional ventilation dynamic simulation software.The study results show that the return air route of the underground east and west wing is optimized and a K45-6-№16 type fan is installed in the 67# line transportation roadway,import air volume of ramp is improved from 15.03 m3/s to 50.12 m3/s,and the import air volume of the connection roadways of -320,-360,-400,-440,-480 m middle sections are 11.33,11.21,11.15,11.09,11.01 m3/s respectively.Therefore,the foal of ramp ventilation smooth is realized,the ventilation disorder phenomenon in ramp connection roadway is improved effectively,besides that,the technical support for safety production of the mine is provided.
