【摘要】 提出利用旧巷或采空区自然净化污风进行系统可控循环通风的新型模型,并从理论上建立起这种通风系统的数学模型,最终导出稳态下的循环风量与自净效率的关系,从而为这种系统可控循环通风方案的设计提供一定的理论基础。通过对红透山铜矿的具体方案的实施,进一步证实这种方案的可行性。更多还原

【Abstract】 The thesis proposes a new-type model for circulating ventilation of controlled system based on self-purification function of the old mine opening or empty district.The mathematic model of this kind of ventilation system is built in theory,and then the relation between circulating flow and self-purification efficiency in stabile state is educed. Thus the thesis provides certain theoretical foundation for the design of circulating ventilation of controlled system.Through the implementation of this scheme in Fushun Hongtoushan Copper mine,its feasibility is verified further.更多还原
