【摘要】 近年来锚杆支护技术快速发展,在巷道围岩控制中的应用也越来越广泛,尤其是在澳、美、英等锚杆支护技术先进国家。我国也在研究推广锚杆支护技术。锚杆支护由于能主动地加固围岩护为主动支护,有效改善了矿井的支护状况,具有施工方便、效率高,有利于加快施工进度,且施工成本低、支护效果好等特点,而成为当今巷道支护改革的主要趋势。更多还原

【Abstract】 The rockbolt support rapidly develops in recent years,Application in controlling in tunnel surrounding rock is also more and more broad,especially Australia-American-United Kingdom etc.for the rockbolt support technology advanced country. Our country also studys and spreads the rockbolt technology.The rockbolt support which can actively reinforce the surrounding rock is active support.It effectively improve the support situation of mines.It has convenient construction and high efficiency.It is beneficial to accelerate construction speed.The cost of construction is low.The support effect is good.It becomes the main trend of roadway support reform nowadays.更多还原
