| 摘 要： | 在分析砾岩分布特征及其水文地质特征的基础上,以矿山压力控制理论为指导,运用岩层沉降理论推断了华丰矿1409工作面在采厚为6.5m的情况下,导水裂隙带发育高度为96.2m,揭示了导水裂隙能够导致顶板砾岩水突出.结合矿山压力观测资料和顶板突水量资料,阐述了矿山压力和顶板砾岩突水突出之间的因果影响关系.根据2407工作面冲击地压监测资料,阐明冲击地压对顶板突水的促进作用.建立了顶板水沿工作面下平巷突出运移的模型,阐明了斑裂线是导致砾岩水大量突出的主要导水通道.

| Abstract: | An analysis based on rock pressure control theory and the distribution and hydro-geological characteristics of the conglomerate above the Huafeng Coal Mine number 1409 working face suggests the fracture zone allowing water inflow is 96.2 m thick while mining the coal layer itself is 6.5 m thick.This fracture zone can lead to water-inrush through the roof.The underground pressure data and roof water-inrush data are correlated.Monitoring the number 2407 working face for rockburst suggests a role for rockburst... |
