Description

High-intensitive rock splitting method and mitotic apparatus based on plane of weakness
Technical field
The present invention relates to the non-explosions of rock to split technical field, especially a kind of high-intensitive rock splitting method based on plane of weakness And mitotic apparatus.
Background technique
Currently, explosion is still, fractured rock is most economical, efficiently method, but in blasting process, it is possible to create concussion of blasting, The ill-effects such as blasting flyrock, toxic gas may be to blow-up point ambient enviroment, Ren Yuanhuo when these explosions harm is out of control Equipment impacts.In recent years, with the reinforcement of people's sense of self-protection and environmental protection consciousness, people increasingly pay close attention to quick-fried Broken harm, in order to ensure the safety of Adjacent Buildings, is reduced because explosion causes especially when burst region is close away from building Dispute, some units in charge of construction are intended to the broken rock technique using non-explosive excavation without using conventional blasting method.These Demand also promotes people to further investigate non-blasting rock-broken method.Currently, the broken rock technique of non-explosion have passed through many years Constantly research there has been significant progress, and compared with conventional blast method, non-blasting method is with high security, noise is small, nothing The advantages that pollution.Currently used non-quick-fried method has:
Static crushing method using static breaking agent cutting marble, granite or is crushed various rocks, concrete and reinforcing bar When concrete structures, can accomplish completely no slungshot, it is noiseless, without friction, without public nuisance from blasting such as poison gases.Breaking size can be completely Meet the requirement that sets, and any object of surrounding will not be damaged, therefore compared with explosive blasting, it has showed very big superior Property.The main feature of static breaking agent is that vibration, air-shock wave, noise, slungshot, poison gas will not be generated in shattering process And dust, be the cracking agent of a kind of nuisanceless or few public hazards, and using easy, do not need to clog, do not need yet line, conducting and Igniting.It is calcium oxide that the king of static breaking agent, which wants expansion sources, it generates chemical reaction with after the blending of suitable water.Work as calcium oxide When being changed into calcium hydroxide, crystal is changed into multiple tripartite's scalenohedron by cubic crystal, and the conversion of this crystal form can cause The expansion of crystal volume, so that the bulbs of pressure are slowly applied to blasthole hole wall.Due to the constraint by blasthole, this expansion Pressure will cause tensile stress around blasthole.For fragile material, tensile strength is much smaller than compression strength, so material Material easily causes broken under action of pulling stress.Test shows that static breaking agent generated bulbs of pressure in blasthole are general Up to 30-40Mpa, and the bulbs of pressure needed for soft rock and concrete generate radial crack are generally less than 10-20Mpa.Therefore, only Reasonable explosive payload and rupture parameters are chosen, the material of certain middle hard rocks and concrete one kind can be crushed.
Carbon dioxide fracturing device, carbon dioxide fracturing technology are a kind of high pressure pneumatic component technologies, are to utilize liquid dioxy Volume, which sharply expands, when changing carbon endothermic gasification generates high pressure, causes coal (rock) body broken or cracking.Can be widely applied to coal mine and All conglomeraties such as non-coal mine, cement, quarrying.Simultaneously especially suitable for coal and gas prominent mine, explosive is substituted, can be used for explosion and fall Coal, Comprehensive Gas Control, bump improvement, extinction, top coal reduction, stone door punching coal, Floor Heave in Roadway improvement, coal bunker block clearing etc..
High-frequency breaking hammer, high-frequency breaking hammer are a kind of broken, reconstruction of the old city town projects, concrete structure for being mainly used in rock Novel hydraulic engineering equipment in the demolition construction of part.In recent years, as country is to city noise pollution and explosion quarrying engineering method The control of harmfulness, high-frequency breaking hammer rely on the flexibility of its work, the diversity of vehicle equipment and its efficient working efficiency, High-frequency breaking hammer is developed rapidly.
As people increasingly pay attention to environment and safety, non-blasting rock-broken method has obtained biggish development, with routine Blasting method is compared, and non-blasting procedure fractured rock cost is higher by very much, but its safety, pollution-free, non-hazardous.But above-mentioned is non-quick-fried Method is only capable of the rock that division intensity is lower than 50MPa, and the superhigh intensity rock that intensity is more than 100MPa is still lacked preferably Construction method.
Disclosed above- mentioned information are used only for enhancing the understanding to background of the present invention in the background section, it is thus possible to Information comprising not constituting the prior art known to a person of ordinary skill in the art in home.
