摘　　要：开磷集团马路坪矿采用锚杆护顶分段空场法开采,开挖后采场顶板用预应力锚索进行支护。为保证采场预应力锚索加固技术安全、经济、可靠,通过力学模型对矿山的预应力锚索的极限承载力、破坏形式及破坏原因进行了计算、分析,获得了锚固段两个界面上的锚固规律,为后续矿山采场的预应力锚索支护工程设计提供了理论依据。Kailin Group＇s Maluping Mine mines ore using sub level open stope with roof-bolting, which the roof of stope is sup ported by prestressed cable. To ensure the supporting technology for the stope safety, reliability and economic in the process of mining operation, calculation of mechanical model for mining is made by analyzing the ultimate bearing capacity of prestressed ca- ble, destroying forms and destroy reason, in result, the anchor- age rules of two interfaces on the anchor segments were get0 which provides a theoretical basis for engineering design of the prestressed anchor support for subsequent mine stope.
