前言1959年是“苦战三年”中具有决定意义的一年,党的八届六中全会在总结1958年的辉煌成就和丰富经验的基础上,确定了煤炭是四大跃进指标之一,因此在短期内迅速提高煤炭产量一番到两番是头等重要的事。为了很好的完成迅速提高我国煤炭产量一番到两番的任务,在近年来除了大力发展水力采煤技术外,在一般矿井必须增加单位工作面的煤产量,因此如何提高单位工作面的产量,是一个非常重要的问题。
Foreword 1959 is a decisive year in the “three years of bitter war.” The 6th Plenary Session of the Eighth Central Committee of the Party, based on a summary of the brilliant achievements and rich experience of 1958, determined that coal is one of the four major leap forward indicators. Therefore, It is of paramount importance that the rapid increase of coal production in the short term quadruples. In order to accomplish the task of rapidly increasing China’s coal production one or two times, in recent years, in addition to vigorously developing the hydraulic coal mining technology, it is necessary to increase coal production per unit workface in general mines and thus how to increase the output per unit of work surface Is a very important issue.
