摘要
针对虎龙沟煤业公司81505工作面特厚煤层大采高综放开采巷道支护难题,采用了高强度、高刚度、高可靠性与低支护密度的"三高一低"的支护技术,解决了超高煤帮、特大断面煤巷支护难题,有效控制了围岩变形,确保巷道安全,并提高巷道掘进速度,为综放工作面的快速推进创造良好条件,使大同矿区的软岩巷道支护技术水平上了一个新台阶。
In view of the problem of roadway support in 81505 working face of Hulonggou Coal Industry Company, the "three high and one low" support technology with high strength, stiffness, high reliability and low support density is adopted to solve the problem of supporting roadway with super high coal side and super large section, effectively control the deformation of surrounding rock, ensure roadway safety, and improve roadway driving speed, create good conditions for the rapid advance of fully mechanized caving face, and make the soft rock roadway support technology level of Datong Mining area a new step.
