Description
Technical field
The present invention relates to a kind of cutting methods of ore pass, belong to coal mining technical field.
Background technology
Mine ore pass is that the ore in top stage casing is put into the pit shaft that lower part haulage drift is passed through using dead weight.It is existing
Ore pass largely using anti-pick method from the bottom up, supporting is carried out on one side up construct while, is laid with when top is blown out safe
Canopy, ventilation are matched using indentation and suction.The shortcomings that prior art：First, generally apart due to upper layer tunnel and below lane
Tens of rice when needing more complicated supporting in high-order blast hole drilling, and will withdraw supporting when blowing out every time, therefore construct
Progress is slow, and engineering cost is high；Second is that due to being always blind hole operation, it is difficult to discharge fume, easily lead to smoke poisoning, operation is dangerous
Greatly.
Invention content
The present invention provides one kind and slips for cutting time long, the costly and poor safety problem of existing ore pass
The cutting method of mine.
The technical solution that the present invention solves above-mentioned technical problem is as follows：A kind of cutting method of ore pass, which is characterized in that
The molding of ore pass is realized by following step：
The first step, hidden hole drilling trepanning：Go out a centre bore from below lane to upper layer underground drilling unit using hidden hole drilling；
Second step installs cage：One winch is set in the tunnel of upper layer, and the rope of winch passes through centre bore, under hanging down
In layer tunnel, and cage is installed in the end of rope；
Third walks, and blows out reaming：Hidden hole drilling is reused, is located in below lane around centre bore and drills out blasthole,
Then worker is promoted by cage, explosive is filled in blasthole, after the completion of explosive filling, worker withdraws, ignition charge, by center
Hole expands, and forms first segment ore pass；Continue to drill out blasthole using hidden hole drilling around centre bore at the top of first segment ore pass,
Reaming is carried out after filling explosive and ignition, forms second segment ore pass；Repeat above-mentioned ream operation, until by lower layer lane
The centre bore in road to upper layer tunnel all completes reaming, forms ore pass.
The beneficial effects of the invention are as follows：Process safety is dug, because opening centre bore, construction ore pass is logical using centre bore
Wind, ventilation effect is good, effectively prevents because of improper ventilation, the possibility of caused blasting fume poisoning；Cage is hung using centre bore,
The expense for eliminating supporting and the protection of safe canopy alleviates the labor intensity of worker, reduces using servant on winch traction cage
Time of worker's work surface up and down.
Based on the above technical solution, the present invention can also be improved as follows.
Further, it is located at the opening in the tunnel of upper layer on the top of the ore pass, carries out putting mouth, make horn mouth
The opening of shape.
Further, reaming procedure is blown out described, after populated explosive, removes cage, put in the lower part of centre bore
Set truck, after ignition charge, broken ore falls directly into truck.The time of muck entrucking can be saved.
Further, a diameter of 100mm of the centre bore.
The present invention relates to mine down-hole ore pass construction method, using digging mode on earth's surface hidden hole drilling, ore pass of first constructing
Centre bore, then the anti-pick construction ore pass by winch and cage safely and fast.
Description of the drawings
Fig. 1 is the structural schematic diagram during a kind of cutting of ore pass of the present invention.
Reference numeral record is as follows：The upper layers 1- tunnel, 2- below lanes, 3- centre bores, 4- winches, 5- cages, 6- ropes,
7- trucks, the main vertical shafts of 8-.
Specific implementation mode
The principle and features of the present invention will be described below with reference to the accompanying drawings, and the given examples are served only to explain the present invention, and
It is non-to be used to limit the scope of the present invention.
A kind of cutting method (referring to Fig. 1) of ore pass, including main vertical shaft 8 and be connected to main vertical shaft 8 neighbouring
Upper layer tunnel 1 and below lane 2 realize the molding of ore pass by following step：
The first step, hidden hole drilling trepanning：Using hidden hole drilling a centre bore 3 is drilled out from below lane 2 to upper layer tunnel 1；
Second step installs cage：One winch 4 is set in upper layer tunnel 1, and the rope 6 of winch 4 passes through centre bore 3, hangs down
Enter in below lane 2, and cage 5 is installed in the end of rope 6；
Third walks, and blows out reaming：Hidden hole drilling is reused, is located in below lane 2 around centre bore 3 and drills out big gun
Then hole is promoted worker by cage 5, explosive is filled in blasthole, and after the completion of explosive filling, worker withdraws, ignition charge, will
Centre bore 3 expands, and forms first segment ore pass；Continuation is drilled out around centre bore using hidden hole drilling at the top of first segment ore pass
Blasthole fills explosive and carries out reaming after igniting, forms second segment ore pass；Repeat above-mentioned ream operation, Zhi Daoyou
The centre bore in below lane to upper layer tunnel all completes reaming, forms ore pass.
Based on the above technical solution, the present invention can also be improved as follows.
It is located at the opening in upper layer tunnel 1 on the top of the ore pass, carries out putting mouth, make opening for bell mouth shape
Mouthful.
Reaming procedure is blown out described, after populated explosive, cage 5 is removed, truck is placed in the lower part of centre bore
7, after ignition charge, broken ore falls directly into truck 7.The time of muck entrucking can be saved.
Further, a diameter of 100mm of the centre bore 3.
In specific construction, some determinations are carried out to equipment and condition：
In the construction of mine ore pass, ZQS-100D hidden hole drilling machine drill 100mm centre bores, the drill hole of drilling machine depth 20 are first used
