前言随着煤矿生产向现代化方向的发展和矿井生产机械程度的提高,矿井规模越来越大,开采深度逐步加深,因此伴随着矿井通风系统也日趋复杂,通风路线越来越长,造成了工作地点的劳动环境恶化和对工作面特别是矿井边远地区的工作面供给足够的风量变得十分困难。解决这个问题的传统方法由于技术上或经济上的原因,显得并非最佳。因而“可以控制的循环通风”(简称可控循环风)这一 Preface With the development of coal mines in the direction of modernization and the improvement of mechanical production in mines, the scale of mines is increasing and the depth of exploitation is gradually deepening. Therefore, with the increasingly complicated mine ventilation systems and longer and longer ventilation routes, work has been caused Deterioration of the working environment at the site and the supply of sufficient air volume to the working face, especially to the workings in remote areas of the mine, have become very difficult. The traditional method of solving this problem is not optimal because of technical or economic reasons. Thus “can control the circulation ventilation” (referred to as the controllable circulation of wind) this one
