【摘要】：朱莊煤礦深部采區(qū)太原組灰?guī)r含水層具有高承壓、強富水、補給充沛、無垂直分帶性、存在強徑流帶和垂向?qū)ǖ�、與奧灰有水力聯(lián)系等特點,自6煤開采以來多次發(fā)生底板灰?guī)r突水事故,最大涌水量1 400 m3/h,嚴(yán)重威脅礦井的安全生產(chǎn)。Ⅲ631工作面回采過程中發(fā)生多次灰?guī)r涌水,針對Ⅲ631工作面水文地質(zhì)條件及底板水害特征,通過引入石油領(lǐng)域地面水平井鉆探工藝,采用地面順層水平井和側(cè)鉆分支水平井鉆探手段對涌水段及未采段進行精確有效探查,再結(jié)合高效的地面高壓注漿控制工藝,對探查到的涌水通道及原生溶隙、構(gòu)造裂隙等進行注漿改造,完成了工作面涌水快速封堵及區(qū)域超前治理。
[Abstract]:The limestone aquifer of Taiyuan formation in deep mining area of Zhuzhuang coal mine is characterized by high bearing pressure, strong water enrichment, abundant recharge, no vertical zonation, strong runoff zone and vertical guide water channel, and hydraulic connection with Ordovician ash. Since No. 6 coal mining, there have been many water inrush accidents of floor limestone, the maximum water inflow is 1 400 m3 / h, which seriously threatens the safe production of coal mine. There are many limestone water gushing in the mining process of 鈪，
