由我院采矿系石琴谱教授领导研究的课题“回采工作面下行通风研究”于1990年6月5日经中国统配煤矿总公司安全局组积鉴定通过。随着采矿工业的发展,全国煤矿回采工作面使用下行通风的将愈来愈多。虽然下行通风有许多明显的优点,它对降尘、降温、防止隅角沼气积聚、抑制采空区自燃等有较好的作用,认识比较统一,但仍有很多问题看法不一致。因此,从理论上和实践上对其进行系统全面的研究是十分必要的。在中煤总公司安全局的领导下,该课题组历时三年多,完成了
By the Department of Mining Department of Qin Shiqin Professor led the study of the topic “mining face down ventilation study” on June 5, 1990 by the China National Coal Mine Safety Corporation identified by the assembly group. With the development of the mining industry, more and more ventilation will be used in coal mining face in China. Although the downward ventilation has many obvious advantages, it has a better understanding of dust reduction, cooling, prevention of accumulation of biogas in the corner, and suppression of spontaneous combustion in the goaf. Although there is still a great deal of consensus on this issue, many opinions are still inconsistent. Therefore, it is necessary to conduct a systematic and comprehensive study both theoretically and practically. Under the leadership of the safety bureau of China National Coal Corporation, the task force lasted for more than three years and was completed
