煤炭生产机械化水平的提高,回采工作面将发生巨大变化。要适应不断发展的机械化生产,就得根据煤层的赋存条件,在巷道布置回采工艺、顶板管理、生产管理上实行技术改革,这样才能充分发挥机械的威力,夺得较好的经济效果。王石凹矿几年来围绕机械化生产,不断进行技术改革,取得了较好成效,就是一个实例。 The level of coal production mechanization, mining face will undergo tremendous changes. To adapt to the continuous development of mechanized production, it is necessary to carry out technical reforms on the basis of the conditions in which coal seams are stored, the layout of the roadway, the roof management and the production management so as to give full play to the power of machinery and achieve better economic results. In recent years, Wang Shihao Mine has been making progress in mechanized production and continuous technological reform with good results. This is an example.
