It is drilled with working face and visits water hole, the regimen in the rock in front of working face is detected using the spy water hole;
After spy water terminates, first lap blasthole, the second circle blasthole, the 3rd circle big gun are drilled with successively in the spy water hole periphery Hole ... until periphery blasthole;
First lap blasthole, the second circle blasthole, the 3rd circle blasthole ... and in the blasthole of periphery, arrange resistance wire;
The swelling agent matched is filled into each blasthole of arranged resistance wire;
The resistance wire is powered, makes wire temperature control swelling agent after predetermined temperature, the scheduled time that is persistently powered Expanded by heating causes blasthole presplitting, stops being powered to the resistance wire;
Driving machine gun head is directed at the spy water hole, and makes the first row pick and the described second circle blasthole phase on big gun head It is corresponding, development machine is started, fragmented rock body, forms initial vallecular cavity;
Using the big gun head of the development machine to the rock around initial vallecular cavity, crushed according to order from inside to outside;
Make the big gun head of the development machine peripherally profile wire cutting rock, form smooth excavation contour line.
Alternatively, the aperture for visiting water hole is 150mm, hole depth 100m;
The aperture 42mm of the first lap blasthole, hole depth 2-3m, pitch of holes 0.1m;
The second circle blasthole arranges that the distance that distance visits water hole gradually increases in the shape of a spiral, between the hole of the second circle blasthole Away from equal with the space width of the first row pick on driving machine gun head.
Alternatively, in the periphery blasthole, every three blastholes are one group, blasthole spacing 0.1m.Every group of blasthole spacing 0.5m, It is evenly arranged on the contour line of tunnel;
In every group of blasthole of periphery blasthole, resistance wire is only arranged in middle blasthole, another two blasthole is used as expansion auxiliary Hole is helped not arrange resistance wire.
Alternatively, the weight proportion of the swelling agent is:
Cement 100, calcium oxide 70, calcium carbonate 10, sodium sulphate 50, water 80.
Alternatively, the weight proportion of the swelling agent is:
Cement 100, calcium sulphoaluminate 20, red mud 50, calcium oxide 80, water 100.

Referring to Fig. 1 and Fig. 2, static blasting of the present invention coordinates the rock lane comprehensive driving method embodiment of development machine, the present invention Embodiment includes step:
S101, it is drilled with working face and visits water hole 1, the regimen in the rock in front of working face is carried out using the spy water hole Detection.
In the present embodiment, suitable for solid coefficient f > 12 rock gangway end face.Solid coefficient f represents the rock failure mechanism of rock It is difficult to degree.F=R/10, wherein, R represents the uniaxial compressive strength of rock.
The aperture for visiting water hole can be 150mm, hole depth 100m.
After S102, spy water terminate, first lap blasthole 2, second is drilled with successively in the periphery of spy water hole 1 and encloses blasthole, the 3rd Circle blasthole 3 ... until periphery blasthole 6.
In the present embodiment, after spy water terminates, first lap blasthole 2, second is drilled with successively in the periphery of spy water hole 1 and encloses blasthole 3rd, the 3rd circle blasthole the 4, the 4th encloses blasthole 5, periphery blasthole 6.
Wherein, the aperture 42mm of the first lap blasthole 2, hole depth 2-3m, pitch of holes 0.1m.
The second circle blasthole 3 arranges that the distance that distance visits water hole gradually increases in the shape of a spiral, the hole of the second circle blasthole 3 Spacing is equal with the space width of the first row pick on driving machine gun head.The specific size of blasthole by development machine pick distribution feelings Condition determines.In the present embodiment, by taking existing MH620 types hard rock mole as an example, first row totally 4 picks on its big gun head, in spiral shell Shape arrangement to be revolved, and is gradually increased apart from the distance of big gun head central shaft, the distance apart from big gun head central shaft is respectively 0.15m, 0.2m, 0.25m, 0.3m.The second circle blasthole 3 shown in corresponding diagram 2 is distinguished in the position of 4 picks of first row on the driving machine gun head Four blastholes, the mark of four blastholes is respectively 3-1,3-2,3-3,3-4.
3rd circle blasthole 4 is arranged in the outside of the second circle blasthole 3, and it is 0.5m that distance, which visits water hole (centre bore) distance,.
4th circle blasthole 5 is arranged in the outside of the 3rd circle blasthole 4, and distance the 3rd encloses blasthole 0.3m.
According to the size of section, the 5th circle, the 6th circle blasthole etc. can be also arranged, the spacing between circle and circle is 0.3m.
S103, first lap blasthole, the second circle blasthole, the 3rd circle blasthole ... and in the blasthole of periphery, arrange resistance Silk.
In the present embodiment, resistance wire is not arranged in the spy water hole as centre bore, in first lap blasthole, the second circle big gun Hole, the 3rd circle blasthole ... and in the blasthole of periphery, arrange resistance wire.The resistance wire is insulation resistance wire.
S104, the swelling agent matched is filled into each blasthole of arranged resistance wire.
In the present embodiment, grouter can be used, the swelling agent matched is filled into each big gun of arranged resistance wire Kong Zhong.
As an alternative embodiment, the weight proportion of the swelling agent is:Cement 100, calcium oxide (CaO) 70, calcium carbonate (CaCO3) 10, sodium sulphate (Na2SO4) 50, water 80.The expansion rate of the swelling agent of the present embodiment is 260.
