主要对矿井回撤工作面全负压通风技术方案进行初步探索,通过分析回撤工作面现场风量、温度、气压等参数的变化规律建立数学模型,并从模型推广应用到现场实际,为回撤工作面全负压通风系统的实施提供了可靠的理论依据。
This paper mainly explores the technical scheme of total negative pressure ventilation in the face of the mine with the retracting face and establishes the mathematical model by analyzing the variation rules of the on-site air volume, temperature and pressure in the face of the mine, and popularizes and applies the model to the actual field. The working face full negative pressure ventilation system provides a reliable theoretical basis.
