CHINA MINE ENGINEERING

Jinchuan mining area has complex geotechnical conditions, where the fractured rock masses and high geostress have increased the difficulty in roadway support and the maintenance cost of roadways. In this paper, a systemic summary is made for the research achievements in roadway support of Jinchuan mining area, and based on years of engineering practice in such area, the widely used technology for reinforcement of the roadways surrounded by high stress fractured rocks in the mining area is concluded to provide reference for roadway support of similar mines.
