通风井场地总平面布置
general layout for ventilation shaft area
tongfengJ}ng ehongd一zongP一ngm}an buzhl通风井场地总平面布置(general layout forventilation shaft area)合理确定地下矿通风井口地面建筑物、构筑物、辅助道路和工程管线等的平面和竖向位置。它是矿山工业场地总平面布置的一个组成部分通风井场地属矿山辅助场地,工业设施仅有通风机房和相应的风道、变配电设施、维检用辅助道路和供电线路。通风机房的布置要与井口所处地形和主导风向相适应,机房与井口应保持20一3om距离,以利反风道的布置。当通风井为料井时,小型机房可直对斜井口布置,大中型机房则要结合地形,在斜井口的侧面布置采用抽出式风机时,机房应布置在当地最小风频的上风侧,并与其他设施保持一定的卫生防护距离。采用压人式风机时,机房应布置在最小风频的下风侧,确保井下风质的卫生标准。 (甘作林)
