Description

A kind of hole sealing device of high pressure gushing water boring and method for sealing
Technical field
The present invention relates to a kind of hole sealing device and method for sealing, particularly relate to hole sealing device and the method for sealing of the boring of a kind of high pressure gushing water.
Background technology
In mine down-hole is produced; usually can run into the gushing water problem of water under high pressure boring; as close bad exploratory hole, freezing hole, inspection eye etc. that down-hole discloses, and exploratory hole, inspection eye etc. that the aperture outburst prevention measures of underground construction lost efficacy (containing without outburst prevention device).This kind of boring, if do not carried out shutoff, impacts underground work environment on the one hand, strengthens mine drainage burden; Just bring larger water yield in short time on the other hand, Mine Safety in Production is threatened.
At present, the shutoff of this kind of boring adopts usually detects in advance, the direct shutoff in aperture, the method for slip casting by force, and this method exists following distinct disadvantage:
