| 摘 要： | 为探索煤矿深井岩巷破碎软弱围岩的支护方法,结合淮南矿业(集团)公司顾桥煤矿-780 m水平南翼轨道大巷的支护工程实践,揭示了深部岩巷的变形规律,并分析了煤矿深部破碎软弱围岩支护的难点及其支护机制,提出顾桥煤矿南翼轨道大巷分步联合支护的设计理念和优化支护方案。结合围岩表面位移、深部位移等现场监测数据,对新旧支护方案的效果进行了对比,研究结果表明,顾桥煤矿-780 m水平南翼轨道巷采用分步联合支护方法取得了较理想的支护效果。深部岩巷的支护受高地应力、岩体力学性质等因素影响,应结合巷道围岩地质条件采取适当的支护措施,让各种支护手段在时间和空间上实现有效结合,充分发挥并提高围岩的自身承载能力。
