裂隙破碎带软弱夹层矿井支护技术研究

Study on Support Technology of Weak Interlayer Mine in Fractured Zone

裂隙破碎带软弱夹层具有膨胀性、崩解性、分散性、流变性和易扰动性等工程力学特点,为了克服不良地质条件下因开挖而引起的大变形,防止矿层因过度变形而产生坍塌,发生塌方事故,本文详细介绍了此类矿层的加固围或阻止其变形的支护方案,并对不同的矿层类别提出了不同的支护方案,为类似矿层的井巷提供借鉴。

The weak interlayer in fractured zone has the characteristics of expansibility,disintegration,dispersion,rheology and disturbance.In order to overcome the large deformation caused by excavation under unfavorable geological conditions and prevent the collapse and collapse of the ore bed caused by excessive deformation,this paper introduces in detail the supporting schemes of reinforcing or preventing the deformation of this kind of ore bed,and also introduces the supporting schemes for different mines.Different support schemes are put forward for similar mining strata.
