Description
Technical field
The present invention relates to a kind of pulsing jets and mechanical shock combined-breaking rock mechanism, and it is high to be best suited for Polodyakonov coefficient coefficient
Rock-boring is broken.
Background technology
2015,《BP world energy sources statistical yearbooks》It points out：China is still the world's largest energy-consuming state, accounts for the whole world
23% and the whole world of consumption figure have a net increase of long 61%；Coal resources consumption accounts for the 66.03% of total quantity consumed, following one section very long
There is irreplaceable status as China's main body energy in period.《National Program for Medium-to Long-term Scientific and Technological Development
(2006~2020)》It explicitly points out：There is an urgent need for strengthen coal resources safety high-efficiency mining energetically and using technical research, be distinctly claimed
Primary study deep layer and bad ground ore body mining technique.2011, National Energy Board's publication《National energy science and technology " 12
Five " planning》The Efficient Development for explicitly pointing out coal resources under complex geological condition is main research direction from now on, it is desirable that research and development
Meet multi-mode stone head driving, technology and equipment under China's complex stratum condition.
At present, coal mining gradually develops to deep layer and bad ground, to deep layer, bad ground coal resources safety
High efficient mining technology and equipment propose higher requirement and new challenge.Due to the increase of crustal stress, usual deep layer, intricately
Elasticity modulus, hardness and breakdown strength of layer coal petrography etc. increase therewith, and uniaxial compressive strength often reaches more than 150MPa.Coal petrography
Drilling is the premise of the engineerings efficient implementation such as ore body explosion, Depressurized mining and roadway support, and hard drilling in coal and rock efficiency it is low,
The problems such as Dust Capacity is big directly constrains the Efficient Development of the ore bodies resources such as deep layer, bad ground coal.At present, underground coal petrography bores
Hole is mainly using machine cut and impact two ways：Tool wear is serious during machine cut broken rock, consumption is big, is mainly used for

Middle work there are button serious wear with come off, efficiency of breaking rock is low and Dust Capacity is big the problems such as, greatly reduce mechanical shock
How rock breaking capacity, efficiency and service life of equipment and reliability realize that safe and efficient crush of hard coal petrography has become
The critical issue and difficult point of the ore bodies resource high-efficiencies such as deep layer, bad ground coal exploitation.
High-pressure water jet broken rock is a utilization " water arrow " impact grinding and coal petrography crushing technology the effects that erosion at a high speed,
Its booster action is it is verified that cutter rock breaking capacity can be improved, tool life, but continuous high-pressure water jet consumption
Water conference causes coal petrography crushing mechanism Work places to generate the ponding of large area, and equipment is caused to be difficult to work normally.Common
Continuous water jet auxiliary rock only generates single " water hammer pressure ", and rock fracture in dynamic indentation ability is limited, and subsequent " stagnation pressure "
It is low to be difficult to aggravate hard coal petrography internal injury and crack propagation, it is caused to fail to obtain widely in hard coal petrography crushes equipment
Using.Pulsing jet impact grinding coal petrography ability can be generated more much stronger than solid jet, pulsing jet auxiliary rock with intermittence
The effects that a " water hammer pressure ", multi-source compression stress wave is superimposed inside coal petrography, reflects, causes coal petrography volumetric fracture and fatigue to break
It is bad.In addition, using the low-temperature impact of pulsing jet and the low characteristic of water consumption, button wear rate and consumption can be reduced, is extended
Button service life improves mechanical shock broken rock operating condition.
