| 摘 要： | 针对煤矿深部综放工作面巷道顶板压力大、变形严重,巷道超前压力与变形影响范围大的特点,分析深部开采巷道压力分布特点与变形规律,提出有效控制深部巷道严重变形的方法,研制出能够适应长距离、大变形深部巷道的两列两节式强力超前支架支护系统;介绍了超前支护系统主要技术参数的确定和主要特点,并对超前支护系统推移机构和稳定机构的适应性进行了分析;此支护系统在兖矿集团东滩矿14310工作面试验,超前支护60 m。经实际测定,巷道顶底板的平均变形量为202 mm,两帮平均变形量为848 mm,与用单体支护相比,巷道的变形量大幅降低;通过试验观测结果分析可知,该支护系统支护效果好,巷道围岩变形较小,满足综放工作面深部巷道支护的要求。
