【摘要】：为解决高原矿山井下低压低氧的工作环境问题,提出了对于高原矿山宜采用以压为主的压抽结合的通风方式,并从理论上分析了人工增压的必要性和可行性。以某高原矿山为背景,结合高原矿山的环境特点,对关键通风参数进行了校核,并以高原适应性修正后的通风关键参数为基础,运用Ventsim三维通风模拟软件搭建了通风系统的三维可视化模型和网络实时解算平台,对增能调节、增阻调节等人工增压方式进行模拟与解算,得出在不同增压方式下的增压效果。研究结果表明:高原矿山宜采用以压为主的压抽结合的通风方式,并通过人工增压的方式有效地提高井下的大气压力,可基本满足井下作业人员的需求,对于高原矿井的增压通风具有适用性和科学性。
[Abstract]:In order to solve the problem of working environment of low pressure and low oxygen in plateau mine, the paper puts forward that the ventilation mode should be combined with pressure and pumping, and theoretically analyzes the necessity and feasibility of artificial pressurization. Based on the background of a plateau mine and combined with the environmental characteristics of a plateau mine, the key ventilation parameters are checked, and based on the adapted ventilation key parameters of the plateau. The three-dimensional visual model of ventilation system and the real-time computing platform of network are built by using Ventsim three-dimensional ventilation simulation software. The artificial supercharging methods such as increasing energy regulation and resistive regulation are simulated and calculated, and the supercharging effect under different pressurization modes is obtained. The results show that it is appropriate for plateau mines to adopt the combined ventilation of pressure and pumping, and to effectively increase the underground atmospheric pressure by artificial pressurization, which can basically meet the needs of underground operators. It is applicable and scientific to supercharged ventilation in plateau mine.
