[0003] At present, in the mine repair process, the method of drilling inclined blastholes and smooth surface (pre-cracking) blasting is adopted. In this way, a lot of rubble will be generated at the foot of the slope during the blasting, and the slope forming effect is not good. The later mechanical repair work The quantity is large, and the cost of construction machinery is high

Embodiment
[0060] Such as Figure 1-Figure 3 Shown, a kind of mine slope restoration blasting construction method, described construction method comprises the following steps:
[0061] S1. Draw the drawings of the finished mine slope; the finished mine slope is stepped from top to bottom as the upper finished platform, the finished side slope, and the lower finished platform; the connection between the upper finished platform and the finished side slope is the top line, The connection between the slope and the lower end platform is the toe line;
[0062] S2. According to the final mine slope drawing, mark the position of each blasthole on the surface of the working face, and the blastholes are relatively located on the top of the upper finishing platform, the finishing side slope, the toe line and the lower finishing platform; by marking at the toe line The blast hole can ensure the integrity of the back slope to a great extent and reduce the workload of mechanical trimming in the later...

The invention discloses a blasting construction method for mine slope repair. The blasting construction method comprises the steps that S1, a final mine slope body drawing is drawn; S2, according to the final mine slope body drawing, the positions of all blast holes are marked on the surface of the working face, and the blast holes are relatively located in the tops of an upper final platform, a final side slope, a slope toe line and a lower final platform; S3, mine slope blasting construction is carried out; S4, ditching and earthing operation is conducted on the surface of the upper final platform and the surface of the lower final platform, and after earthing operation is completed, vegetation is planted; and S5, net arranging and hanging operation is conducted on the surface of the final side slope, and then planting soil materials are sprayed and seeded; According to the method, the blast holes are marked at the slope toe line, so that the integrity of the rear slope toe can be ensured to a great extent, and the workload of later mechanical finishing is reduced.
Description
technical field [0001] The invention belongs to the technical field of mine side slope treatment, in particular to a blasting construction method for mine side slope repair. Background technique [0002] During the mining process, a large amount of land that cannot be used without treatment will be produced, also known as mining abandoned land. There are various pollutions caused by production in the abandoned land; in order to meet the needs of ecological restoration, it is necessary to restore and regreen the mine; [0003] At present, in the mine repair process, the method of drilling inclined blastholes and smooth surface (pre-cracking) blasting is adopted. In this way, a lot of rubble will be generated at the foot of the slope during the blasting, and the slope forming effect is not good. The later mechanical repair work The quantity is large, and the use cost of construction machinery is high. Contents of the invention [0004] Aiming at the deficiencies in the prio...
