Abstract

Purpose. Each ventilation system has its own important elements, such as the various branches of the system, which can be connected in a normal and diagonal pattern, ventilation regulators and fans. Based on a professional approach to the analysis of this aeration system, a comparison of reliability results has been conducted, which indicates the real state of the microclimate in underground mines, affecting the increase in the prospects for the development of mining activity. Methods. This paper deals with the problem of ventilation in underground mines, especially in diagonal systems, and the importance of regulating ventilation to provide the required amount of air (Q, m3/min) through the entire system, taking into account the determination of the main fan depression. Findings. To ensure the required (designed) amount of air through the system branches, various methods of effective regulation are used in mining engineering. Therefore, based on research and measurements in different mine workings, our findings provide complete safety and comfort of microclimate during mining activity. Originality. The measurements performed and the database created according to the values and results obtained from the analytical calculations present the best possible estimate, which is substantiated in the paper. Practical implications. The problem of calculating and regulating aeration for a simple diagonal system has been solved, taking into account the determination of the main mine fan depression before and after the use of aeration regulators.

矿井简单对角线系统通风调节的有效性
目的。每个通风系统都有自己的重要元素,例如系统的各个分支,它们可以以正常和对角线的方式连接,通风调节器和风扇。采用专业的方法对该曝气系统进行了分析,并对可靠性结果进行了比较,这表明了地下矿山小气候的真实状态,影响了采矿活动发展前景的增加。方法。本文论述了地下矿井,特别是对角线系统的通风问题,以及在确定主风机降风量的同时,调节通风以使整个系统提供所需风量(Q, m3/min)的重要性。发现。为了保证通过系统分支所需(设计)的风量,采矿工程中采用了各种有效的调节方法。因此,通过对不同采场的研究和测量,我们的研究结果提供了采矿过程中完全安全舒适的小气候。创意。根据从分析计算中获得的值和结果进行的测量和创建的数据库提供了最好的估计,这在本文中得到了证实。实际意义。解决了简单对角线系统通风量的计算和调节问题,同时考虑了通风量调节器使用前后矿井主风机落差的确定。
