Gob Area Grouting Reinforcement

This paper mainly introduced the grouting reinforced governance issues of old goaf of which exist building on the surface. Combined with the engineering example, the use of GTS software to identify mined areas and the the drilling histogram to establish three-dimensional geological model of gob region. Put forward to carry out positioning quantitative grouting technology on the goaf according to three-dimensional geological model, and strengthen the gob by using grouting method.
