摘要
结合实际,系统地分析了影响轻放工作面回采率的各种因素,从改进放煤工艺增加配套设施、自行研制节煤器、合理开采设计等几个方面入手,阐述了提高轻放工作面回采率的几种途径。
Based on the coal-mining activites, all sorts of factors are analyzed, that can influence the rate of coal mining in a coal face with lingt hydraulic supports. The several methods of increasing the mining rate of coal faces are stated from these aspects ： improving the techniques of blasting coal down the roof, using suitable facilities, self- developing coal - saving machines, and making proper mining system.
