Description
Technical field
The present invention relates to a kind of pulsing jet and mechanical shock combined-breaking rock mechanism, be best suited for Polodyakonov coefficient coefficient high
Rock-boring or broken.
Background technology
2015, " BP world energy sources statistical yearbook " was pointed out: China remains energy-consuming state the biggest in the world, accounts for the whole world
The 23% of consumption figure and the whole world have a net increase of long 61%；Coal resources consumption accounts for the 66.03% of total quantity consumed, the longest one section in future
As China's main body energy, there is irreplaceable status in period." National Program for Medium-to Long-term Scientific and Technological Development
(2006～2020) " explicitly point out: need badly and strengthen coal resources safety high-efficiency mining energetically and utilize technical research, be distinctly claimed
Primary study deep layer and bad ground ore body mining technique.2011, " the national energy science and technology " 12 that National Energy Board issues
Five " planning " to explicitly point out the Efficient Development of coal resources under complex geological condition be main research direction from now on, it is desirable to research and development
Meet multi-mode stone head driving, technology and equipment under China's complex stratum condition.
At present, coal mining the most gradually develops, to deep layer, bad ground coal resources safety to deep layer and bad ground
High efficient mining technology and equipment are had higher requirement and new challenge.Due to the increase of crustal stress, usual deep layer, intricately
The layer elastic modelling quantity of coal petrography, hardness and breakdown strength etc. increase therewith, and uniaxial compressive strength often reaches more than 150MPa.Coal petrography
Boring is the premise of the engineering efficient implementation such as ore body explosion, Depressurized mining and roadway support, and hard drilling in coal and rock efficiency is low,
The problems such as Dust Capacity is big directly constrain the Efficient Development of the ore body resource such as deep layer, bad ground coal.At present, down-hole coal petrography bores
Hole mainly uses machine cut and impact two ways: when rock is broken in machine cut, tool wear is serious, consumption big, is mainly used in
The coal petrography of broken Polodyakonov coefficient coefficient f≤8 of cutting；Mechanical shock can be with shatter most coal petrography, but at hard coal petrography (f > 15)
Middle work exist button serious wear and come off, the problem such as efficiency of breaking rock is low and Dust Capacity is big, greatly reduce mechanical shock
How rock breaking capacity, efficiency and service life of equipment and reliability, realize the safe and efficient broken of hard coal petrography and have become as
The key issue of the exploitations of ore body resource high-efficiency such as deep layer, bad ground coal and difficult point.
It is a coal petrography crushing technology utilizing effect such as " water arrow " impact grinding and erosion etc. at a high speed that high-pressure water jet breaks rock,
Its assosting effect it is verified that cutter rock breaking capacity can be improved, tool life, but continuously high-pressure water jet consumption
Water yield conference causes coal petrography crushing mechanism Work places to produce large-area hydrops, causes equipment to be difficult to normally and works.Common
Water jet auxiliary rock only produces single " water hammer pressure " continuously, and rock fracture in dynamic indentation is limited in one's ability, and follow-up " stagnation pressure "
Low being difficult to aggravates hard coal petrography internal injury and cracks can spread, causes it to fail in the broken equipment of hard coal petrography and obtains widely
Application.Pulsing jet impact grinding coal petrography ability can produce many with intermittence much stronger than solid jet, pulsing jet auxiliary rock
Individual " water hammer pressure ", multi-source compression stress wave causes coal petrography volumetric fracture and fatigue to break in coal petrography effect such as internal superposition, reflection etc.
Bad.Additionally, utilize low-temperature impact and the low characteristic of water consumption of pulsing jet, button wear rate and consumption can be reduced, extend
Button service life, improve mechanical shock and break rock working condition.
