Description

The inclined shaft deep hole grouting structure of a kind of effective reinforce adjoining rock and shutoff underground water burst
Technical field
The utility model relates to a kind of metallurgical mining technique field, is specifically related to a kind of structure simply, stable performance, the inclined shaft deep hole grouting structure of easy to operate effective reinforce adjoining rock and shutoff underground water burst.
Background technology
During metallurgical mining, inclined shaft often will be set to increase work plane, shorten mining and transport duration, and the main slant that skip bucket inclined shaft promotes as ore, carry the key effect of installing inclined shaft skip, in tunneling process, due to complicated geological, in addition around well, rock is poor, tunnel surrounding water yield is large, tunnel difficulty by force large, and, the infiltration of face surrounding is serious, easily cause cave-in accident, construction safety is difficult to be guaranteed, for this reason, develop a kind of structure simple, effective reinforce adjoining rock, shutoff underground water burst, avoid country rock in driving to collapse in a large number and a large amount of water burst causes and floods well accident, ensure that effective reinforce adjoining rock of construction safety and the inclined shaft deep hole grouting structure of shutoff underground water burst are the effective ways addressed this problem.
Utility model content
It is simple that the purpose of this utility model is to provide a kind of structure, prevents mine from caving in, is conducive to construction effective reinforce adjoining rock of personal safety and the inclined shaft deep hole grouting structure of shutoff underground water burst.
The purpose of this utility model is achieved in that and comprises face and injected hole, and described injected hole is arranged at face periphery, coordinates in wearing anchor formula with face.
The utility model is in slope construction process, at rock crusher, the structure of deep hole grouting is adopted when water yield is large, at face periphery bored grouting, reinforce adjoining rock, shutoff underground water burst, achieves the smooth driving of skip bucket inclined shaft, avoids country rock in driving and to collapse in a large number and a large amount of water burst causes well accident of flooding, ensures construction safety; Effectively save supporting and the draining investment of follow-up driving, and be that under similar execution conditions, slope construction provides important references.The utility model reduced investment, the duration is short, safety good, Functionality, quality and appealing design, effectively alleviates labor strength.
Accompanying drawing explanation
Fig. 1 is the utility model overall structure front-view schematic diagram;
Fig. 2 is that the utility model overall structure is overlooked and looked schematic diagram;
In figure: 1-face, 2-injected hole, 3-left hole, 4-right ports, 5-interstitial hole.
Detailed description of the invention
Be further described the utility model below in conjunction with accompanying drawing, but must not be limited the utility model by any way, any change done based on the utility model training centre or improvement, all belong to protection domain of the present utility model.
As shown in accompanying drawing 1 ~ 2, the utility model comprises face 1 and injected hole 2, and described injected hole 2 is arranged at face 1 periphery, coordinates in wearing anchor formula with face 1.
Described injected hole 2 comprises left hole 3, right ports 4 and interstitial hole 5, and three is arranged in both sides and top country rock respectively.
Described left hole 3 and right ports 4 at least comprise respectively and are arranged at drift angle hole and both sides parallel hole on side.
Described left hole 3 to have a down dip structure for left avertence, itself and 0 ~ 15 ° to the left of inclined shaft center line, horizontal by 0 ~ 25 ° of tilt angled down.
Described right ports 4 to have a down dip structure for right avertence, itself and 0 ~ 15 ° to the right of inclined shaft center line, horizontal by 0 ~ 25 ° of tilt angled down.
Described interstitial hole 5 is arranged in the country rock of inclined shaft top, is 0 ~ 25 ° of tilt angled down with center line.
Described injected hole 2 bore size is Φ 80 ~ Φ 120mm, and whole hole dimension is Φ 50 ~ Φ 80mm, hole depth 40 ~ 100m.
Described injected hole 2 arranges orifice tube, and described orifice tube outer end consolidation arranges grouting valve.
Described periphery, injected hole 2 end is filled up and is arranged Anchor Agent and geotextiles mixed coating.
Operating principle of the present utility model and the course of work as follows:
The utility model is in slope construction process, on earth's surface, drilling machine punches, in the crack and fine grained rock mass of tomography and water burst band, ground cave, the hole of rock mass particle, the interface of rock-soil layer or ground, the slurry material with filling, bonding capacity is injected by boring, tomography and water burst band rock mass through the filling of slurry, densification, permeate, splitting, after consolidation, rock mass strength, stability and water proof water resistance are improved, ensure that tunnel or underground construction can normally be implemented.
The utility model is at rock crusher, the structure of deep hole grouting is adopted when water yield is large, at face periphery bored grouting, reinforce adjoining rock, shutoff underground water burst, achieve the smooth driving of skip bucket inclined shaft, avoid country rock in driving and to collapse in a large number and a large amount of water burst causes well accident of flooding, ensures construction safety; Effectively save supporting and the draining investment of follow-up driving, and be that under similar execution conditions, slope construction provides important references.
Before boring, released the position in every hole by survey crew, mark out drift angle and the drilling depth in this hole with red paint.Down-the-hole drill executes brill by the position, hole of survey crew releasing and design drift angle on chassis, after angle reserved by rig, takes omnibearing measure, prevents the precision of rig flutter effect drilling construction; Spud in and adopt early stage low speed to creep into, when rig normally creeps into (general drilling depth about 0.5m), rig speed is adjusted to normal running speed.The situation such as boring procedure close observation rate of penetration, water burst, rock stratum, performs record in time, to projected depth, can carry out next process.The utility model has reduced investment, the duration is short, safety good, Functionality, quality and appealing design, effectively alleviates the feature of labor strength.
