Taking Hunan coal mines practicing fully-mechanized mining technology as the engineering background, the paper analyzes problems of practicing fully-mechanized mining technology and proposes the countermeasures of solving these problems, which originate from coal mining technology conditions, middle-small geological exploration technology, mining roadways layout of complicated seam, roadways fast driving technology, excavating fully-mechanized mining technology through the fault and fast moving technique of working faces. Results show that the coal faces which are successful practiced conventional machine mining technology can be completely practiced fully-mechanized mining technology, and that it is worthy of support from several aspects such as policy and fund.
