综放大断面切眼锚网索支护技术

Bolt-mesh-anchor Supporting Technology for Large Section Open-off Cut of Fully-mechanized Working Face

针对某矿306综放工作面大断面切眼支护难题,按照锚网索联合支护机理,结合现场实际地质生产条件,提出了锚网索联合支护的方案。现场实践表明,围岩变形在控制范围内,锚网索支护结构可靠,可以保证工作面安全生产。

To solve the large section open-off cut problem on No.306 fully-mechanized working face, bolt-mesh-anchor combined supporting plan was proposed based on supporting mechanism and actual geological condition. The practice showed that the surrounding rock deformation was under control and the bolt-mesh-anchor supporting structure was reliable, so that it could ensure the safety production of the working face.
