Water stopping device and water stopping method for mining deep development drill

Abstract

The invention provides a water stopping device for a mining deep development drill and a water stopping method of the water stopping device, and relates to the field of mining development drills. The mining deep development drill water stopping device comprises a drill bit driving block, a driving motor is arranged in the drill bit driving block, a drill bit rotating rod is fixedly connected to the upper end of the driving motor, and a drill bit plugging mechanism is arranged on the outer side of the upper end of the drill bit rotating rod; the drill bit plugging mechanism comprises a drill bit body, a limiting rotating plate, a rubber air bag, an inflation pipe and a water guide grouting pipe. The drill bit plugging mechanism further comprises a drill bit body, a limiting rotating plate, a rubber air bag, an inflation pipe and a water guide grouting pipe. Before grouting of a grouting pipe is carried out in an existing mining deep development drill water stop device, a gushing channel needs to be drilled in advance, a large amount of time, material resources and financial resources consumed by plugging and water stop are consumed, operation steps are complex, the plugging and water stop efficiency is reduced, the plugging and water stop cost is increased, and manpower, material resources and the time consumed by plugging and water stop are reduced.

Description

technical field [0001] The invention relates to the technical field of mining development drills, in particular to a water-stopping device and a water-stopping method for deep mining development drills. Background technique [0002] When carrying out the mining development step, it is necessary to use the mine drill bit for prospecting treatment. Since the remaining drill hole after drilling by the prospecting mine drill bit is inconvenient to plug, when the deep development and excavation construction is carried out to the vicinity of the drill hole position, the groundwater will pass through the drill hole. Directly leaking into the excavation and excavation channel will easily affect the normal construction progress, and at the same time, it has a large safety hazard. During the construction of excavation and excavation inclined wells, there is a certain risk of well flooding, which is a great threat to the safety of construction personnel. sex. [0003] Before grouting ...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a water-stopping device and a water-stopping method for deep mining drilling, which solves the problem that the existing deep mining water-stopping device needs to perform grouting on the gushing channel before grouting the grouting pipe. Drilling holes in advance consumes a lot of time, material and financial resources for sealing and sealing water, which reduces the efficiency of sealing and sealing water and increases the cost of sealing and sealing water
