1) working face prediction
工作面预测
3) face pre-grouting
工作面预注浆
1.
Through blasting in grouting holes the cracks with low connectivity are penetrated successfully, then regular face pre-grouting is used to block effectively off heavy water-gushing.
通过注浆孔内爆破的方法,成功地将连通性很差的岩石裂隙贯穿,再采用常规的工作面预注浆方法将井筒特大涌水进行了有效封堵,探索出连通性很差的裂隙含水层注浆工艺的新路子。
2.
According to engineering examples,the paper introduces the experience that the face pre-grouting affects thick aquifer and large water inflow shaft water prevention and control construction,as well as the successful experience of using chemical grout for blocking water in the aquifers including tiny cracks and pores.
本文依据工程实例,介绍了工作面预注浆对厚含水层、大涌水量井筒施工防治水经验,并介绍了化学浆液在细微裂隙和孔隙发育含水层中注浆堵水的成功经验。
