| 摘 要： | 急倾斜煤层高阶段综放开采中有可能导致瓦斯积聚而形成新"爆炸源"。顶煤超前注水(或湮水)对开采扰动区(Excavation Disturbed Zone,EDZ)瓦斯等气体迁移规律的影响也许会对安全开采产生耦合效应。利用"固-液-气"模拟实验装置、数值模拟与现场监测,深入分析了急倾斜特厚煤层高阶段综放开采过程中"顶煤-水-瓦斯"三相介质运动演化、耦合作用及迁移规律。

| Abstract: | The high stage caving of steep coal bed probably has the gas accumulated to form a new "source of explosion".The impact of top-coal injection(or water submerging) to the migration of gases in Excavation Disturbed Zone may generate the coupling effect for safe mining.By the use of "solid-liquid-gas" simulation experiment devices,numerical simulation and on-site monitoring,in-depth analysis is adopted to find the steep extra-thick coal bed's high-stage excavating process of "top-coal-water-gas" three-phase me... |
