Description
Technical field:
The present invention relates to roadway blasting construction method.
Background technology:
At present both at home and abroad total rock tunnel blasting technology construction jewel hole amount is big, time-consuming, laborious, take gunpowder, and driving speed is low, many
Number coal mine excavation imbalance, adjust difficulty, particularly medium-length hole and deep hole blasting technology solve slotting problem owing to having no idea and
Can not well apply, as a whole, existing total rock tunnel blasting has a disadvantage in that
1, jewel hole quantity is many, and powder charge is many, detonates often.
2, waste gunpowder is many.
3, the harmful gas produced is many.
4, blasting energy is big, is easily caused rock crusher, roof fall wall caving.
5, the engineering time is long, and efficiency is low.
Summary of the invention:
The invention reside in and design a kind of total rock tunnel blasting speed of application soon, efficiency is high, it is achieved medium-length hole blasting is easy,
Save gunpowder, the new method that protection country rock is effective.
The technical scheme is that the new method that a kind of total rock tunnel blasting is constructed, it includes cannelure, borehole, wink
Electric detonator, delay electric detonator, mining explosive, rapid hardening glue, stemming, blow out line, exploder, earpick, punching water pipe and tamper
Deng.It is characterized in that: be respectively arranged and cannelure being perpendicular to, with extraordinary rig, the inside and outside of cannelure that work surface gets out
The parallel borehole of bus.Borehole depth within cannelure more than the degree of depth of cannelure, borehole depth cannelure outside and
The deep equality of cannelure.After earpick and the clear hole of water pipe, clear hole, the borehole within cannelure first fills carry out the coffin upon burial in wink medicine and explosive,
Breeching mud, rapid hardening glue, stemming the most successively.Borehole outside cannelure, first fills priming and the explosive of delay electric detonator, then breeching
Mud, uses common serial or parallel connection method connect big gun and can make the borehole once detonation inside and outside cannelure after installing big gun.Explosion
Time the detonation wave that produces of carry out the coffin upon burial in wink medicine and explosive within cannelure the rock pillar of cannelure inner bottom part is broken, and by high-temperature gas
Rock pillar in cannelure is dished out outside groove by the pressure produced, and the borehole outside cannelure detonates subsequently, outside avalanche cannelure
Rock.
The present invention can also be achieved in that:
A kind of new method of stone head blast working, it include cannelure, borehole, instant electric detonator, delay electric detonator,
Mining explosive, rapid hardening glue, stemming, blow out line, exploder, earpick, punching water pipe and tamper etc..It is characterized in that: by special type
Rig is perpendicular to the inside and outside of cannelure that work surface gets out and is respectively arranged the borehole parallel with the bus of cannelure.Annular
Borehole depth within groove is more than the deep equality of the degree of depth of cannelure, the borehole depth outside cannelure and cannelure.With drawing
After ear picker and the clear hole of water pipe, clear hole, the borehole within cannelure first fills carry out the coffin upon burial in wink medicine and explosive, more successively breeching mud, rapid hardening glue,
Stemming, explosive, the priming of delay electric detonator and stemming, the borehole outside cannelure, first the dress extension time is more than inside cannelure
In borehole, the delay priming of time and the explosive of electric cap, refill stemming, uses common method to connect big gun can after installing stemming
So that the borehole once detonation inside and outside cannelure.The detonation wave that during explosion, carry out the coffin upon burial in wink medicine and explosive within cannelure produces is by ring
The rock pillar of shape groove inner bottom part breaks, and the pressure produced by high-temperature gas groove of being dished out by the rock pillar in cannelure is outer and collapse broken.Ring
Borehole outside shape groove detonates subsequently, the rock outside avalanche cannelure.
The main feature of the present invention:
1, first arrange cannelure at work surface, work surface rock mass is divided into cylindrical-shaped structure, shape around borehole
Become the omnibearing scope of freedom, the stress of rock when changing explosion, it is possible to reach a big gun cavitation, the effect of two big gun grooving
Really.
2, provide, for deep hole blasting, the free space that fractured rock expands.
3, straight eye explosion can be realized, improve blast hole utilization factor.
4, the efficiency of borehole avalanche rock is high.
5, reducing borehole number, shorten drilling time, save gunpowder consumption, the harmful gas produced during explosion is few, reduces
Ventilate and dispel the time used by blasting fume.
6, driving speed can be greatly improved, reduce excavation cost, open up make new advances for solving coal mine excavation imbalance
Approach.
