Abstract
The invention discloses a kind of deep hole high voltage transient gas broken rock three-stage hole-sealing technology method, this method is equipped with three sections of sealing material, mixing of the first segment with cement, gypsum, aggregate and water by a certain percentage first；Second segment is single aggregate；Third section is the mixing of cement, gypsum and water.Since sealing material mobility is preferable, therefore grouting under pressure device is not needed by three sections of sealing material injection holes in sequence during sealing of hole, can directly poured into sealing material in hole.The present invention can reduce the cost of sealing material on the basis of ensuring sealing of hole intensity, and easy to operate.
Description
Technical field
The present invention relates to hole sealing technology field more particularly to the hole-sealing technologies of deep hole broken rock.
Background technique
Sealing of hole is an important link in rock break-off process.The effect of sealing of hole will affect final broken rock capacity usage ratio.Envelope
The factors such as Porous materials intensity difference, sealing of hole leakproofness are likely to result in broken rock shock wave and go out from plane of weakness, and big energy is caused to damage
It loses；Simultaneously it is also possible to being damaged to site operation personnel.The sealing of hole of high quality can make full use of to enable measuring, and may be used also
Improve safety.
Common sealing material has solid particle, cement mortar and three kinds of chemical material.Wherein, solid particle flow
Difference, when drilling is relatively deep or longer, it is difficult to completely tight to block.Cement mortar setting time is longer, and early strength is poor, drags slow engineering
Progress.Chemical material is expensive, saves difficult.
The universal higher cost of sealing material at present, when punching deeper, in order to which save the cost will not usually block entire brill
Hole.This may cause rock breaking efficiency poor because sealing of hole intensity is low, leakproofness is poor, result even in the accidents such as winged pipe.It is existing in order to solve
There is the deficiency of method and technology, the present invention provides a kind of new deep hole hole-sealing technology methods.
Summary of the invention
In order to solve the above technical problems, technical solution provided by the invention are as follows: one kind is broken for deep hole high voltage transient gas
Rock three-stage hole-sealing technology method, comprising the following steps:
It (1) is from bottom to top respectively first, second and third section of sealing of hole stage by drilling；
(2) first segment hole-sealing technology: after accelerated cement, gypsum and aggregate are mixed into siccative, by solid, liquid (water) matter
Amount 1:1 is mixed to obtain sealing of hole slurries, because sealing of hole slurry fluidity is good, can directly be rapidly injected in first segment deep hole, the
One section of sealing of hole requires completely to seal fracturing pipe, and at the top of sealing of hole slurries to be more than 20~25cm of fracturing pipe；
(3) second segment hole-sealing technology: directly pouring into second segment sealing of hole stage vestibule for aggregate, it is added enter aggregate volume answer
Account for 90% of residual volume in second segment sealing of hole stage vestibule；
(4) phase III hole-sealing technology: mixed by solid, liquid (water) quality 1:1 after accelerated cement, gypsum are mixed into siccative
Conjunction stirs to get slurries, and slurries are quickly poured into phase III hole and fill up hole, completes sealing of hole process.
Preferably, the aggregate diameter 3-8mm.
Preferably, the gypsum is anhydrite.
Preferably, the whipping process of the sealing of hole slurries carries out in agitator, is stirred using blender, then will
Sealing of hole slurries are poured directly into hole.
Preferably, the accelerated cement is that 42.5 sulphate aluminium cements are mixed with additive.
Preferably, the additive being added is respectively lithium carbonate, calcium sulfate, polycarboxylate water-reducer.
The present invention has the advantage that present invention process method and step is simple, it is easy to operate, and improve the quality of sealing of hole
And rock breaking efficiency, it reduces and flies the generation of the accidents such as pipe；Sealing material is at low cost, configuration convenience, and has good mobility, is not required to
Extraneous pressurized equipment is wanted, it is easy to operate, save the sealing of hole time.
Detailed description of the invention
Fig. 1 is the principle of the present invention structural schematic diagram.
Wherein, 1- fracturing pipe, 2- drilling, 3- first segment sealing of hole, 4- second segment sealing of hole, 5- third section sealing of hole.
Specific embodiment
In conjunction with attached drawing, one kind being used for deep hole high voltage transient gas broken rock three-stage hole-sealing technology method, comprising the following steps:
It (1) is from bottom to top respectively first, second and third section of sealing of hole stage by drilling；
