摘要
为研究复杂水文地质条件下的底板水害治理方法,以赵固一矿为例,通过井上、下联合注浆的方式对工作面底板进行注浆加固,尤其对于断层带、物探异常区、工作面初采和停采线附近等矿压易集中区域及水文地质条件复杂区域实施针对性注浆。实践结果证明:通过联合注浆,底板水得到有效控制,未能形成有效突水通道,工作面安全回采得到切实保证,目前18060工作面已安全回采100 m。研究结果可为焦作及全国类似受底板水害严重威胁的矿井提供参考和借鉴。
In order to study the treatment methods of floor water hazards under complex hydrogeological conditions,taking the 18060 working face of Zhaogu No.1 Mine as an example,the working face floor was grouted and reinforced by combined grouting above and below,especially for fault zones and abnormal geophysical prospecting areas,targeted grouting was implemented in areas that are prone to concentration of mine pressure and areas with complex hydrogeological conditions,such as the initial mining of the working face and near the mining stop line.Practical results have proved that,through this grouting method,the floor water of the 18060 working face was effectively controlled,an effective water inrush channel cannot be formed,and the safe mining of the working face is effectively guaranteed.The research results can provide reference and reference for Jiaozuo and similar mines in the country that are seriously threatened by floor water damage.
