采煤机现状与发展

Status and development of shearer

针对薄煤层采煤机和厚煤层采煤机发展现状存在的问题,结合采煤机的发展趋势,指出了采煤机研究方向:提高采煤机行走系统和摇臂行星机构等关键部件可靠性;加强前沿技术和基础理论研究;预研新型结构采煤机。

According to problems existed in development status of thin seam shearer and thick seam shearer,research directions of shearer technology were put forward combing with development trend of shearer,which were improving reliability of key components such as shearer haulage system and ranging arm planetary mechanism,strengthening research of advanced technology and basic theory and studying shearer with new structure in advance.
