河北省煤炭资源丰富,开采历史悠久,是我国主要产煤区之一。前些年,重采轻掘,造成采掘失调。尽快的把开拓掘进搞上去,是我省煤炭工业调整的重要任务之一。近几年的实践使我们体会到,因地制宜,从抓掘进机械化作业线入手,是发展机械化的一条正确途径。到目前为止,我省现有的三十四个生产矿井中有三十二个矿使用了装载机械,其中有四个矿(峰峰二矿、三矿、孙庄矿及开滦吕家坨矿)实现了掘进机械化矿井。一九七八年组织机械化作业线配套以来,开拓、掘进的机械化程度不断提高,由一九七七年的
Hebei Province is rich in coal resources and has a long history of mining. It is one of the major coal producing areas in China. A few years ago, re-mining light dig, resulting in mining disorders. It is one of the important tasks for the coal industry in our province to adjust as soon as possible in the pioneering excavation. In recent years, we have realized through practice that according to local conditions, we must tackle the issue of mechanized operation of tunneling and start the development of a mechanized correct way. So far, 32 of the 34 existing production mines in our province have used loading machinery, of which four are Mine (Fengfeng No.2 Mine, No.3 Mine, Sunzhuang Mine and Kailuan Lujiaotuo Mine) to achieve mechanized mining tunnel. Since the organization of mechanized operation lines in 1978, the mechanization of pioneering and driving progress has been continuously enhanced. From 1977
