深井矿山通风治尘前沿技术及发展态势

Cutting-edge Technology and Development Trend of Ventilation and Dust Control in Deep-level Mines

介绍与评析我国地下矿山在开采深度大通风困难条件下,一些矿山采用多级机站通风系统,提高有效风量降低装机功率的做法;对污风净化再利用技术进行了详细介绍与推荐;推出一些矿山用空区岩体预热冷空气防治冬季冻井的经验做法;对地下矿山除尘前沿科技进步手段进行介绍与研判。

This paper introduces and evaluates the method of adopting multi-stage ventilation station to increase effective air volume and reduce installed capacity in some mines under the conditions that underground mines in China is deep in mining depth and difficult for ventilation.Polluted air purification and reuse technology is introduced and recommended in detail.Experience and practice of some mine using empty area of rock mass to preheat cold air to prevent and treat frozen wells in winter are introduced.Methods of cutting-edge technology advancement for underground mine are introduced,studied and evaluated.
