摘要
针对急倾斜煤层巷道支护现状,在试验巷道探索采用锚网索支护技术。对试验巷道表面位移、围岩深部位移和锚杆(索)受力进行了现场监测,分析了试验巷道围岩变形规律。试验表明,在急倾斜煤层巷道采用锚网索支护是可行的,为锚网索支护在急倾斜煤层巷道的推广应用和支护参数设计提供了依据。
According with the supporting status quo of steeply inclined seam roadway, in experimental laneway the application of Bolt - mesh - anchor support system was explored. The surface displacement and deep displacement of surrounding rock of experimental roadway, and bolt/cable pressure were monitored in-situ. This paper analyzes the deformation of surrounding rock of experimental roadway. The experiment showed that boltmesh - anchor support system could be applied to support steeply inclined seam roadway, This provide basis for supporting parameters design and the popularized application of Bolt - wire mesh - anchor support system in steeply inclined seam roadway.
