受控循环通风技术国内外研究概况

摘要

通过对我国地下矿山开采过程中已经出现的或即将出现的通风问题进行了分析,评述了国内外学者对受控循环通风进行的理论研究、实验研究、试验研究和现场实践研究几个阶段取得的成果,从受控循环通风的可行性、循环模型、经济性和安全性等多方面进行了分析探讨.研究结论为:受控循环通风是一项在合理控制下安全、实现方式简单、经济效益明显的通风应用技术,可以广泛应用于金属非金属矿山井下通风困难区域的应用研究.%The existing and upcoming ventilation problems in the underground mining is analyzed in this paper; and the achieve-ments is also reviewed in this paper, which are acquired from the theoretical research, experimental study, experimental investigation and field practice research of controlled circulation ventilation by domestic and foreign scholars; The feasibility, cycle model, economy, security and so on of controlled circulation ventilation are analyzed and discussed in many ways. The research conclusion is that the controlled circu-lation ventilation is a safe ventilation application technology with simple realizing way and obvious economic benefits under the reasonable controlling, which can be widely used in the difficult ventilation area of underworking of metal or nonmetal mine.
