Implementation structure for finding and breaking down-the-hole drill bit

Technical Field

The utility model relates to the technical field of blasting structures, in particular to an implementation structure for finding and breaking a down-the-hole drill bit.

Background

The mining process of mine mainly relies on the mode that hydraulic pressure down-the-hole drill punched the blasting, because the hardness difference of ore and drill bit quality are uneven, the accident that takes place the drill bit absolutely and can't take out in the hole in the drilling process can take place occasionally, after taking place the accident that the broken drill bit can't take out, the workman can utilize GPS record position coordinate, and insert the material object mark in the big gun hole that has the broken drill bit, confirm the position of roughly disconnected drill bit according to the material object of artificial mark after the blasting and seek. The height of the blasting step is determined according to different conditions of each mine, and if a broken drill bit is left below the required blasting depth by 1-2 meters, the height can be accurately found by using the recorded coordinates after the ore is cleared from the blasting step. If the broken drill bit is left in the required blasting depth, different displacements of the blasting layer occur after blasting, and the broken drill bit is difficult to find by using the original recorded coordinates.

If the mined ore needs to be crushed and sorted, the broken down-the-hole drill bit with high hardness enters a crushing station and a sorting plant along with the ore, and the destructive power to crushing equipment and sorting equipment is huge. In a certain concentrating mill, the broken drill bit enters crushing equipment, so that the equipment loss is more than 30 tens of thousands, and the loss is huge. Therefore, in order to ensure the safety production of enterprises, the broken down-the-hole drill bit must be found in time after the bench blasting of the stope. The unit of punching is for stopping the down-the-hole drill fracture can't seek, can punch 1 thousand 2 hundred meters by original down-the-hole drill and shorten to 800 meters and just directly change new drill and punch, has reduced nearly 30% life of drill bit, causes very big waste.
