摘要
主要研究巷道由于采用喷射混凝土支护而使巷道表面凹凸不平,从而导致巷道的散热面积增加，进而影响风流温升的相互之间关系。本文做了对巷道有理论根据的简化．并形成巷道模型,在此基础上进行理论分析,最终得出在热害矿井中喷射混凝土支护是否可继续被采用。
Increasing of dispersing heat area caused by lane surface unevenness by jetting cement support influences wind temperature increasing. The paper mainly studies their relation. Authors simplified lane on the basis of some theory and made analysis and got a conclusion at last.Jetting cement support is used or not in heat harmful mine pit.
