Embodiment Construction
[0038] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.
[0039] Depend on figure 1 The vertical projection diagram of the curtain grouting method of a kind of orebody roof karst fissure development and strong water-rich deposit of the present invention shown and combined figure 2 It can be seen that the roadway 2 is located below the water level line 6, and each chamber 1 is arranged laterally along the roadway 2.
[0040] 1) Arrangement of upward exploration and injection holes: 6 exploration and injection holes at 5°, 15° and 25° are arranged in each chamber 1, forming a drilling control network within 8m×8m. The design of the exploration and injection drilling is based on the center of the chamber, and the six 5° exploration holes 3, the six 15° exploration holes 4, and the six 25° exploration holes 5 are evenly arranged on the plane staggered by 60°. 50m deep. The 5°, 15° and 25° injection h...
