本文针对跃进煤矿综采工作面巷道端头区域顶板支护支架强度小、支撑性能差、损坏严重,造成工作面巷道端头区域顶板维护越来越困难且经常发生冒顶、底鼓、片邦、拘邦等,导至巷道端头区域断面缩小,并多次发生较严重的冲击地压等问题,造成工作面巷道在服务期间需要不断整修加固,甚至多次翻修,增加了回采成本且安全性能又差,给安全生产工作带来诺多的不便,鉴于上述问题,介绍了一种通过增强支架支护强度,改进支撑适应性能的新型支护液压支架,在使用后取得了很好效果。
In this paper, according to the low strength, poor supporting performance and serious damage of the roof supporting bracket in the roadway end area of the fully mechanized mining face in Yuejin Coal Mine, it is more and more difficult to maintain the roof of the roadway in the working face and the roof, bottom drum, And so on, leading to the section of the end of the tunnel narrowing the area, and more serious impact on the ground pressure and other issues, resulting in the face of the tunnel during the service needs continuous renovation and reinforcement, or even renovated several times, an increase of recovery costs and safety performance In view of the above problems, a new type of supporting hydraulic support that improves the supporting adaptability by enhancing the supporting strength of the supporting bracket has been introduced, which has achieved good results after being used.
