掘进巷道过断层破碎带施工工艺研究
|
摘要
为了保证掘进巷道安全快速过断层破碎带,提高破碎顶板稳定性,大同煤矿集团虎龙沟煤矿机掘一队通过技术研究,决定对21505巷过F3断层期间采取下山掘进施工工艺,并对断层破碎顶板采取"注浆+施工交错密集JW型钢带+架棚"等联合支护措施。实际应用效果表明,取得了显著成效。
In order to ensure the safe and rapid passing through the fault fracture zone and improve the stability of the broken roof in the driving roadway, the No. 1 mechanized driving team of Hulonggou Coal Mine, based on technical research, decided to apply down-hill excavation technology during the passage of F3 fault in roadway 21505,and adopt combined support measures of "grouting + construction of staggered and dense JW-shaped steel belt +scaffolding" for the breaking roof of the fault. The actual application effect showed that remarkable results have been achieved.
