The Application of Curtain Grouting Technology in a Certain Coal Mine Water Stop Project
In response to the demand for safe mining in a certain coal mine,a trial section curtain grout-ing scheme was designed for three underground aquifers.The drilling spacing,drilling depth,and grouting hole structure were optimized,and a grouting hole construction process diagram was developed.The trial sec-tion curtain grouting construction was carried out.On site experiments showed that the use of curtain grouting method has a good water stopping effect and has reference value in similar projects.
