我国煤炭综合机械化开采已经取得较大的发展。然而,就我国目前综采发展水平来看,与世界先进产煤国家相比仍有较大差距。为了找出综采发展的症结所在,1987年对全国173个综采工作面进行了调查研究,并运用统计学分析方法,对影响综采的一些基本问题,如采煤机开机率,各项事故影响程度和影响综采单产的多因素综合分析等进行了探讨。初步掌握了影响综采单产的各种因素及其相互关系,为提高综采单产水平,改进综采工作面生产状况,提供参考。
China’s coal mechanized mining has made greater development. However, judging from the current level of comprehensive mining development in our country, there is still a long way to go compared with the advanced coal-producing countries in the world. In order to find out the crux of the development of fully mechanized coal mining, in 1987, 173 fully mechanized coal mining face in China was investigated and studied. And some statistical analysis methods were used to analyze some basic problems that affect fully mechanized mining, such as coal machine startup rate, The extent of the accident and the multi-factor comprehensive analysis that affect the yield of fully mechanized mining. Preliminary grasp of the various factors affecting the yield and its interrelation of fully mechanized mining, in order to improve the level of production of fully mechanized mining, improve production status of fully mechanized mining face, provide reference.
