摘要
沈阳红菱矿用国产采煤机在大倾角工作面实现综合机械化采煤的经验分析。
The paper is a summary report about fully mechanized mining at steep coal face at Hongling coal mine, Shenyang coal Bureau, where coal face is equipped with MLS3-170 shearser. The author analyses and calculates cutting resistance force of drums, driving force under steep coal face condition as well as analyses damage of hydraulic motors under steep coal face condition.Based on results of analysing, the author retrofitted the MLS3-170 shearer and makes the shearer suitable for steep coal face condition.
