The 40 years developmental review of the fully mechanized mine roadway heading technology in China

Reviewed the development course of China fully mechanized mine roadway heading in the passed 40 years and summarized the present status of the fully mechanized coal mine roadway heading technology and equipment in China.Summarized the problems existed in the fully mechanized mine roadway heading technology and equipment in China underground mines and pointed out that the factors mainly of the time to set up the support,the dust control efficiency at the heading face,the component reliability and the automatic control technology would restrict the mine roadway heading speed.In comparison with the overseas,analyzed the gap of the cutting technology,the component reliability,automatic control technology,the dust control system and the system matching technology of the domestic roadheader.Finally provided the development orientation of the boom type roadheader and the fully mechanized mine roadway heading technology in China,it is improving the flexibility of the completed machine and expanding the application scope,having the fundamental technical research,improving the application performances of the components and developing the matching technology of the fully mechanized mine roadway heading system.
