As one of the more commonly used equipment in the coal mining industry, explosion-proof diesel engines continue to promote the normal operation of coal mines. However, at the same time, its existing problems are becoming more and more obvious. Only by studying these problems and determining the future development trend of explosion-proof diesel engines can we better promote their application in the coal mining industry. Therefore, this article will carry out specific research and analysis on explosion-proof diesel engines through the overview, application status, existing problems of explosion-proof diesel engines for coal mines, and future development trends of explosion-proof diesel engines for coal mines, hoping to provide better application and development of explosion-proof diesel engines with doing something about it.展开更多

It is mainly characterized by artistry, comprehensiveness and creativity and is loved by pre-school teachers. Therefore, Olff's teaching method has also become one of many music teachers' teaching methods. Based on this, this paper focuses on the analysis of the characteristics of Orff's music teaching method, and elaborates the practicality of this teaching method in pre-school education for reference.展开更多
