| 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. |
