隐伏导水陷落柱快速判识与超前探查治理技术

Rapid identification and advanced exploration treatment technology of concealed water guiding subsided column

根据唐家会出水点的水量、水位、水温、水化学场一致性的原理,判别出61101掘进工作面突水水源为深部强富水奥灰水,通道为隐伏导水陷落柱(定性)。为此,封堵了出水巷道、防止出水水量由渐变到灾变扩展(预防);利用槽波地震和音频电透视、钻探等综合探查确定了隐伏导水陷落柱的位置、范围与空间形态(定位);采用计算机仿真技术确定在其中深部实施"底部封堵、上部充填"治理方案,构建了"阻止采动裂隙向下扩展与奥灰水向上渗流的隔水层段"充填加固技术方案(超前治理),避免重大恶性突水事故的发生,取得了"绿色快省高效"的定性、预防、定位、超前探查治理隐伏导水陷落柱的新模式。

According to the water content,water level,water temperature,water chemistry field consistency principle,rapid identification of 61101 working face water inrush water of Ordovician limestone water is deep and strong for the channel,hidden water flowing subsided column(qualitative). For this reason,the water discharge tunnel is blocked and the water quantity is prevented from gradual change to sudden catastrophic expansion(prevention);The location,range and spatial form of concealed water guiding subsided column are determined by means of trough wave, seismic and acoustic wave,electrical prospecting and drilling;Computer simulation technology was used to determine the "bottom plugging and upper filling" treatment plan in the deep part,and a "reservoir section that prevents mining fractures from expanding downwards and Austrian gray water from seeping up" was constructed. In order to avoid the occurrence of major malignant water inrush accidents, a new model of qualitative, preventive, positioning, and advanced investigation and treatment of hidden water diversion pillars has been achieved.
