平凉新安煤业公司井田位于侏罗纪深部软岩地层,因压力大,巷道变形快,导至井下通风设施损坏严重,造成漏风,经修善后又损坏,再次漏风。为了解决这一恶性循环问题,通过研究及应用均压通风技术、构筑柔性可收缩承压墙,延缓了通风设施因围岩大变形而受损漏风。
Pingliang Xin’an Coal Company Mine Field is located in the deep Jurassic deep soft rock formation, due to pressure, roadway deformation fast, leading to serious damage to the underground ventilation facilities, resulting in air leakage, after the repair and damage, once again air leakage. In order to solve this vicious circle problem, through the research and application of pressure equalization ventilation technology, a flexible shrinkable pressure-bearing wall is constructed to delay the damage of the ventilation facilities due to the large deformation of the surrounding rock.
