Center of working face is stated using rock drilling equipment to digging within ore body into obtaining and visiting water hole, if not finding there is water within the spy water hole
Exudation carries out in next step；
Step 2: along with the working face at appropriate inclination angle direction using rock drilling equipment to dig within ore body into,
The spy water hole surrounding obtains multiple snubbers, and makes each snubber and the spy the water hole not phase within the ore body
It hands over, if not finding there is water exudation within the snubber, carries out in next step；
Step 3: all snubber centers are formed on the working face in step 2 line periphery, along with institute
The vertical direction of working face is stated using rock drilling equipment to digging within ore body into several relievers being obtained, if not finding described auxiliary
Helping within eye has water exudation, carries out in next step；
Step 4: placing appropriate explosive and ignite within Xiang Suoshu snubber, explosion face is formed after explosion, if not finding institute
There is water exudation in the explosion face of stating, carries out in next step；
Step 5: a distance obtaining unit roadway is tunneled along the direction vertical with the working face, this section distance is made
For cyclic advance；
Step 6: step 1 is repeated to step 5, so that all unit roadways obtained is successively joined end to end, roadway digging
It completes.
The roadway segmentation system of attack further includes walking after carrying out step 3 with below carrying out before progress step 4
It is rapid:
Along the direction vertical with the working face (1) using rock drilling equipment from the working face edge to ore body within
It digs into obtaining several periphery holes, periphery hole has a water exudation if not finding, carries out in next step.
The quantity of the periphery hole is no less than 4.
Spy water hole depth described in step 1 is 5m.
Cyclic advance described in step 5 is 3m.
Snubber aperture described in step 2 is identical as reliever aperture described in step 3.
Snubber quantity described in step 2 is no less than 4.
Inclination angle between snubber central axis described in step 2 and the working face is less than 80 °.
The quantity of reliever described in step 3 is no less than 4.
The beneficial effects of the present invention are: technical solution of the present invention is used, by segmentation digging driving, in each digging
Before driving, several eyelets are dug out first, judged within the ore body of front in advance with the presence or absence of ponding, to follow at every section
Within ring drilling depth, guarantees normally going on smoothly for mining operation, infiltration water leak accident is avoided the occurrence of, in addition, by working face
Several periphery holes are dug out, so that molding roadway wall surface is more straight, the surrounding shape of control molding roadway, digging of the invention
The features such as process has construction technique simple, low in cost, and security and reliability is high.
Detailed description of the invention
Fig. 1 is digging of the present invention roadway structural schematic diagram obtained.
In figure: 1- working face, 2- visit water hole, 3- snubber, 4- reliever, 5- periphery hole.
Specific embodiment
Be described further below technical solution of the present invention, but claimed range be not limited to it is described.
As shown in Figure 1, the present invention provides a kind of roadway segmentation system of attack, comprising the following steps:
Step 1: choosing ore body surface portion region as working face 1, along the direction vertical with working face 1 from work
1 center of face using rock drilling equipment to dig within ore body into, obtain and visit water hole 2, if not finding to visit within water hole 2 has water exudation, into
Row is in next step；Further, it is preferable to which visiting 2 depth of water hole in step 1 is 5m.
Step 2: along with working face 1 at the direction at appropriate inclination angle using rock drilling equipment to digging within ore body into water is being visited
2 surrounding of hole obtains multiple snubbers 3, and keeps each snubber 3 and spy water hole 2 non-intersecting within ore body, if not finding to draw
There is water exudation within slotted eyes 3, carries out in next step；Further, 3 aperture of snubber and 4 hole of reliever in step 3 in step 2
Diameter is identical.3 quantity of snubber is no less than 4 in step 2.Inclining between 3 central axis of snubber and working face 1 in step 2
Angle is less than 80 °.
Step 3: all 3 centers of snubber are formed on working face 1 in step 2 line periphery, along with work
The vertical direction in face 1 is using rock drilling equipment to digging within ore body into several relievers 4 being obtained, if not finding within reliever 4
There is water exudation, carries out in next step；Further, it is preferable to which the quantity of reliever 4 is no less than 4 in step 3.
Step 4: placing appropriate explosive and ignite within to snubber 3, explosion face is formed after explosion, if not finding explosion
There is water exudation in face, carries out in next step；
Step 5: a distance obtaining unit roadway is tunneled along the direction vertical with working face 1, this section distance, which is used as, to be followed
Ring drilling depth；Further, it is preferable to which cyclic advance is 3m in step 5.
Step 6: step 1 is repeated to step 5, so that all unit roadways obtained is successively joined end to end, roadway digging
It completes.
Using technical solution of the present invention, dug out first several before each digging driving by segmentation digging driving
A eyelet, judged within the ore body of front in advance with the presence or absence of ponding, to guarantee digging work within every section of cyclic advance
Normally going on smoothly for journey, avoids the occurrence of infiltration water leak accident, in addition, by digging out several periphery holes on working face, so that
