When there is drop shaft leak stopping in d, drop shaft storage bin, from bottom to top or from top to bottom shaft in eyelet is inserted through the drop shaft borehole wall by root in drop shaft along drop shaft, if there is shaft can insert in drop shaft storage bin, then between this shaft and the shaft that can not insert drop shaft storage bin above it, there is drop shaft leak stopping;
E, to take out shaft can not be inserted in drop shaft storage bin in eyelet in spiral tunnel, drilling rod is inserted again from eyelet, punching to drop shaft leak stopping position with hammer drill, cutter is near drop shaft storage bin axis place, the boring of energy blasting charge is formed at drop shaft leak stopping position, stop punchinging operation, from eyelet, take out drilling rod;
F, will to load in eyelet with priming device explosive, and with shaft, explosive to be filled in boring, and blastic fuse is led in spiral tunnel;
G, connected with initiator by blastic fuse in spiral tunnel, detonating charge, the force of explosion that explosive blasting produces destroys drop shaft leak stopping, makes drop shaft storage bin slip ore deposit unimpeded.
In the method for above-mentioned spiral disposal drop shaft leak stopping, in step a, described spiral tunnel drives up along drop shaft storage bin is spiral by the gradient of 15-25%.
In the method for aforesaid spiral disposal drop shaft leak stopping, in step a, between the inwall in spiral tunnel and the drop shaft borehole wall, keep 5m distance.
In the method for aforesaid spiral disposal drop shaft leak stopping, in step a, in step b, vertical direction distance 2m between adjacent eyelet.
In the method for aforesaid spiral disposal drop shaft leak stopping, in step a, in step c, described shaft is bamboo pole, reinforcement bar or pvc pipe etc.
Compared with prior art, the present invention has following beneficial effect:
1, the equipment wanted required for the present invention is very common and simple, reduces the cost disposing drop shaft plugging operations widely, has the economic benefit of highly significant;
2, the present invention can determine the concrete position of drop shaft generation leak stopping accurately, fast, and by means of only simply, easily operating procedure just can eliminate drop shaft leak stopping;
3, the explosive amount of process leak stopping consumption of the present invention is few, successful;
4, spiral tunnel of the present invention can act on the duty cycle of whole footrill-drop shaft system; And the leak stopping at any position of drop shaft can be processed;
5, safety is good, and explosive is placed in the leak stopping position at drop shaft axis place by the present invention, and detonates in spiral tunnel, avoids the injury of Harmful effects from blasting to disposal personnel to greatest extent, greatly increases operational security;
6, detonating charge installation position is generally within drop shaft axis place, Harmful effects from blasting to the drop shaft borehole wall without any breakdown operation.
