竖井竖井vertical shaftshuJIng竖井(vertieal shaft)用于提升矿石或废石、升降材料和设备、运送人员、敷设管路和电缆等的垂直井筒。井口直接通地面的叫明竖井,不直接通地面的叫盲竖井。竖井按井内所装备的提升容器,分为罐笼井、其斗井和混合井。竖井的断面规格,主要取决于提升容器的种类、数量、外形尺寸,井筒装备的类型和规格,最小安全间隙,管路、电缆和梯子间的平面布置尺寸,要求通过的风量及允许的风速等因素。竖井井颈的5一10m深度内,需用混凝土或钢筋混凝土支护。中国竖井直径一般为4一sm,最大深度为1127m,南非竖井直径已达9·sm,最大深度为2374m。罐笼井井内装有双罐笼或带平衡锤的单罐笼。适用于矿石年产量不大于30万t的矿井,用以提升矿石、废石和升降人员、材料及设备,也可以作进风井,但作进风井时,井筒中的最大风速不允许超过sm/s。它的缺点是,在同样提升高度和同样断面规格的条件下,提升能力比箕斗井低,且井筒装备较复杂。箕斗井井内装有双箕斗或带平衡锤的单箕斗,用以提升矿石或废石。它的优点是提升能力大,井筒装备较简单;缺点是功能单一,只能提升矿石或废石,个别矿山也用它作出风井,但井筒内允许的最大风速不得超过zZm/S。混合井井筒中设有箕斗和罐笼两套提升设备,箕斗用于提升矿石,罐笼用于辅助提升。当矿井开拓深度较大或工程地质条件复杂、施工难度较大时,为减少井筒数目,可考虑用混合井。它的优点是功能全面,开拓工程量小,投资省,管理集中。缺点是两套设备同时提升,难免互相干扰;一套提升设备检修时,另一套提升设备也得停工;一般不兼作风井。圆井断面为圆形,直径主要取决于年产量,一般为4.0一8. Om。圆井承载地压能力强,使用寿命长。井壁一般采用整体混凝土或喷射混凝土支护,也曾用过混凝土预制件、砖、料石等,因其整体性和封水性较差,施工中效率低,难以实现机械化,已逐渐被淘汰。椭圆井是由已变形破损的方井改建而成,使用很少,但它像圆井一样,具有较大的抗地压能力。方井断面为长方形,其承压能力较差;通常采用木材支护,支护材料因耐久性差,且无封水性,已很少使用。
