摘　　要：为实现窄煤柱大断面沿空巷道底鼓的有效控制,以6307工作面回风平巷为研究对象,结合现场条件及支护方案分析了巷道的底鼓特征和变形原理,并采用底板锚杆支护方式控制底鼓。现场应用后,6307工作面回风平巷底鼓突出问题得以解决,其中,煤柱侧、实体煤侧底鼓量分别为159~246、 197~379 mm,回风平巷底鼓量整体较小,巷道断面可满足采面后续回采需求。In order to realize the effective control of floor heave in large-section gob-side roadway with narrow coal pillars,the characteristics and deformation mechanism of floor heave were analyzed based on the field conditions and support scheme of 6307working face return air roadway,and floor bolt support was adopted to control floor heave.After the field application,the prominent floor heave problem of the return air roadway of 6307 working face can be solved,among which the floor heave of the coal pillar side and the solid coal side were 159-246 mm and 197-379 mm respectively,the floor heave of the return air roadway was small on the whole,and the roadway section can meet the subsequent mining needs of the mining face.
