高山地区矿井通风高山地区矿井通风mine ventilation in high elevation areagaoshan diqu kuangjing tongfeng高山地区矿井通风(mine ventilation in highelevation area)向海拔千米以上地区的矿井通人新鲜空气的过程。空气温度、大气压力随着海拔高度而变化。海拔每上升100m，气温下降约0.65C，气压下降约0.93325kPa。不同海拔的气温、大气压力可按下式计算:th~t。一月△H/100 P卜~P，一a△H/100式中t、、P。分别为在海拔高度为H米处的气温，C和气压，kPa;ta、P。为附近气象台站的年平均气温，C和年平均气压，kPa;△H为海拔高度为H处与附近气象台站间的高度差，m;口为气温梯度，夕一。，5一0.7C/10om;a为气压梯度，a~6一8(0.799932一1 .066576)kPa/100rn。随着海拔高度的增加，空气重率则降低。即y一y0(1一H/443。。)5256。式中孔为标准状态下的空气重率，kg/m3。空气重率的降低引起通风风阻、通风阻力、扇风机的全压以及扇风机电机输人功率下降，但风量保持恒定，因此，扇风机效率不随海拔高度变化。以上参数可按下式计算:R一KrR。;h二Krho;H一KrH、Q=Q。;N=K:N。;7=夕。，式中R。、h。、H。。、Q。、N。、军。为标准状态下的风阻、阻力、全压、风量、功率和效率;R、h、H、Q、N、7为海拔高度为H处的风阻、阻力、全压、风量、功率和效率。、r一哥一(‘一H/“300，525弓式中K，为高程校正系数。因此，在通风设计时，不需要进行高程校正，高山矿井扇风机在实际运转时，其风量不变，风压降低，其值为设计风压乘以高程校正系数K二。 (赵梓成)
