It is nearer apart from building, with conventional blasting method not only complicated construction technique, it is difficult to implement, be not easy to operation, can also produce
Violent vibrations and with slungshot, operational security is low, and can produce noise effect environment.And occur in that adopt in the prior art
The method of fractured rock with swelling agent, but this method operating rate is low, and environmental suitability is poor.
The content of the invention
In order to solve deficiency of the prior art, it is an object of the invention to provide a kind of efficient, safety, noiseless influence
The heat energy rock cleavage crush method of environment.
To achieve the above object, the present invention uses following technical scheme：
Heat energy rock cleavage crush method, the crush method specifically includes following steps：
1）The scope of freedom is arranged on rock, broken hole is then bored on the scope of freedom of rock；
2）Hot gas propellant and clay are loaded successively from bottom hole portion in broken hole, and with expansion at the aperture in broken hole
Bolt locking is to block aperture, and the hot gas propellant is that can produce the mixture of hot gas, wherein hot gas propellant after being heated
Inside is embedded with igniter, and the conductor wire of igniter draws broken hole from expansion bolt；
3）Energization igniter and light hot gas propellant, hot gas propellant light it is heated after decompose and produce high-temperature gas,
High-temperature gas expands in closed broken hole and causes catalase.
The hot gas propellant is the mixture of thermite and bicarbonate.
The mole ratio of the thermite and bicarbonate is 1：1-2.
The aperture in the broken hole is 38-150mm, and the depth for crushing hole is 16-36 times of aperture.
More than the broken Kong Weiyi rows or two rows, it is two or more often to arrange broken hole；When broken hole is more than two rows, phase
Row's spacing that adjacent two rows crush hole is 5-15 times of aperture.
The pitch of holes for often arranging two neighboring broken hole in broken hole is 5-10 times of aperture.
The filling height of the hot gas propellant is 0.4-0.5 times of broken hole depth, and expansion bolt is stretched into broken hole
Depth is 50-350mm, is tamped between hot gas propellant and expansion bolt with clay.
The torque of expansion bolt locking is（10~15kN）× 0.5 × d × 10-3, d are the aperture in broken hole, and d=
38-150mm。
The clay is dauk.
The present invention lights the mixture of thermite and bicarbonate with electric energy, because thermite burning produces substantial amounts of heat
The material for making bicarbonate etc. easily be thermally decomposed, which is gradually decomposed, produces quantitative high-temperature gas, and high-temperature gas expands in closed pore
Huge pressure is produced, when pressure is to when being enough to overcome rock internal stress to make rock rupture in petrosal foramen, rock initially forms crack,
Hole internal volume increases simultaneously, the easily decomposed substance accelerated decomposition such as bicarbonate, hyperbar in hole is kept for about 2-3 seconds time, from
And the rock that makes to be broken fully cleaves broken, engineering objective is realized.In a word, crush method of the invention has advantages below：1st, nothing
Vibrations endanger, produced without slungshot, noiseless influence environment；2nd, construction technology is simple, is easy to operation, and operational security is high；3rd, ring
Border adaptive faculty is strong, and the relative method crushed using swelling agent of operating rate is greatly improved.
