摘要
本文根据国内外煤炭矿井和其它地下工程地质条件不断恶化的趋势,针对工作面塌落造成的危害,从岩石力学的观点出发,探索出用超前锚固控制岩体的变位的方法,是防止塌落的最佳选择。通过成功的工程实例,初步论证了超前锚固的必要性和可靠性,对锚杆加固机制做了充实.在此基础上,为超前锚固提供了一种效益高,“全天候”、“全方位”的新型锚杆。
As a result of the bad tendency of the geological conditions in demestic and foreign coal mine wells and some underground engineering,considering the danger caused by face fall, the method of adopting advanced anchorage to control the rock changing position is put for- ward in the view of rook mechanics in this paper,which is the best way to prevent the fall. With the initial proof about the necessity and reliability of the advance anchorage given by the use of successful examples,the anchoring mechanism is enriched. A high-efficiency,all-weathers,all-directions and new-model anchors are provided for the advanced anchoring according to the theory.
