Selection and Calculation of Gravity Drain Line in No.7 Mining Area of Guozhuang Coal Mine

摘要:

郭庄煤矿七采区北翼涌水点标高94m，排水管出水口标高143m，涌水口与出水口垂直落差49m。根据流体力学知识，计算得出排水管路的扬程损失小于49m，满足水自流要求，安设煤矿井下用聚氯乙烯型排水管路两趟，实现绿色、环保、节能排水。

Abstract:

Pouring water point elevation in north limb of No.7 coal mining area in Guozhuang coal mine is 94m, the elevation of water outlet of drainage pipe is 143m, and the vertical drop of pouring water point and the outlet is 49m. According to fluid mechanics, head loss of drainage pipe is less than 49m, which can meet the requirements of gravity flow. Installing two lines of PVC pipes in coal mine can realize energysaving and environmental protection.
