摘要
在中厚煤层开采中,综合机械采煤方法具有许多应用优势。这将充分发挥生产效率,从而进一步提高煤矿开采效率和经济效益。在放顶煤开采中,如何提高回收率一直是困扰煤矿的重要问题。鉴于此,结合对整个机械采煤技术的分析,讨论了提高采煤工作面回收率的措施,旨在促进全采煤技术的发展,并取得较高的效益。
In the mining of medium thick coal seam,the comprehensive mechanical mining method has many application advantages,which will give full play to production efficiency,so as to further improve coal mining efficiency and economic benefits.In top coal caving mining,how to improve the recovery rate has always been an important problem perplexing coal mines.In view of this,combined with the analysis of the whole mechanical mining technology,the measures to improve the recovery rate of coal face are discussed,in order to promote the development of the whole mining technology and obtain higher benefits.
