辽宁阜新煤矸石山生长季的风况研究

Study on the wind velocity of coal gangue pile in growing season in Fuxin mining area,Liaoning Province

采用野外观测与统计分析相结合的方法,对阜新市孙家湾煤矿矸石山不同坡向的风速变化进行研究。结果表明:在整个生长季中,对于排矸年限相同的样地,阳坡的风速均大于阴坡;阳坡样地A的平均风速减弱系数比阴坡样地A低13.67%。风速由大到小的次序为5月>6月>7月>9月>8月。生长季盛行西南风和南风。

The wind velocity variation of different slope directions at coal gangue piles in Sunjiawan was studied with field measurement and statistical analysis. The results showed that the wind velocity of sunny slope exceedsshade slope in all growing season to same dumping years. The weakening coefficient of wind velocity to plot A in sunny slope is under 13.67% by plot A in shady slope. The order of wind velocity from big to small is arranged from May, June, July, September, to August. Southwest and southern winds are prevailing in the growth season.
