摘　　要：通过对淮南国投新集一矿综放面矿压显现规律、瓦斯管理等因素的分析,提出综放面风巷分期掘进的必要性,并推出其适当掘进时间的公式,同时提出分期风巷的现场生产管理要点。By the analysis of strata behaviors and gas managements in fully-mechanized top caving face of XinJi No.1 coal mine in HuaiNan,this paper gives the necessity that return passage of fully-mechanized top-coal caving face should be drived by stages,deduces the formula about the proper time for its driving,and brings forward the main managing measures for the spot driving of time-return passage.
