近几年来,作者带着机采工作面机组割煤工序粉尘浓度高,尘毒危害严重,截齿割煤极容易产生摩擦火花,引燃截割空间积聚瓦斯,潜伏严重事故隐患这一极待解决的课题,先后到国内一些重点局、矿的典型机采工作面进行通风防尘和防治瓦斯的专题调查。1985年又赴英国米特兰矿区和英国煤炭科学院进行专业学习和安全技术考察,结合我国现有的技术水平,仅就采煤机冷却截齿和喷雾除尘系统整体设计改进问题提几点不成熟的意见,供采煤机设计者参考。
In recent years, the author with the machine mining face coal-cutting process unit dust concentration is high, serious dust poisoning, cutting coal cutting very easy to produce friction sparks, igniting the accumulation of cutting space cutting gas, latent serious hidden danger of this extreme To solve the problem, one after another to a number of key domestic Bureau, mining machine face mining ventilation and dust prevention and control of gas special investigations. In 1985, he went to England’s Mitland Mining Area and the British Academy of Coal Science for professional study and safety technology inspection, combined with China’s current state of the art, only on the shearer cooling picks and spray dust removal system overall design and improvement of several immature The views for the shearer designer reference.
