基于Fluent的高原矿井通风增压增氧技术研究

我国中东部地区矿山资源的长期开发,导致资源储量越来越少,而随着西部大开发战略的实施,资源丰富、地域广阔且已有一定经济技术水平的西部地区,必将在未来国民经济发展中占据越来越重要的地位.我国西部地区多为高原,高原矿井井下通风供氧不足是长期困扰高原采矿工作者的一个难题.本文针对目前高原矿井生产面临的低压缺氧问题,以普朗铜矿为...

Study on plateau mine ventilation pressurization and oxygenation technology based on Fluent software

With the long-term development of mine resources in the central and eastern regions of China, the reserves of resources are becoming less and less. With the implementation of China"s western development strategy, the western region, which is rich in resources, broad in territory and has a certain level of economy and technology, will play a more and more important role in the future national economic development. Most of China"s western regions are plateaus, insufficient ventilation and oxygen supply in underground mines in plateau mines have been a problem that has long plagued mining workers in the plateau. Aiming at the current low-pressure anoxic problems faced by the mine production in the plateau, this paper analyzes the current ventilation situation of the mine with the Pulang copper mine as an example, and proposes the ventilation method with oxygen boosting as the main purpose and artificial boosting as the main measure. According to the relevant theories of aerohydrodynamics and mine ventilation, the feasibility of the overall boosting and local boosting ventilation methods is analyzed and compared, and a boosting method combining energy-increasing adjustment and resistance-increasing adjustment is proposed and established according to the actual situation of the mine The model uses Fluent software to verify the effect of the use of pressurized oxygenation technology on the designated stope space, analyzes and summarizes the simulation results, further verifies the feasibility of manual pressurized oxygenation ventilation technology, and provides a certain reference for the selection of mine ventilation methods in the plateau.
