Description
Technical field
The present invention relates to winning equipment, more particularly to a kind of mining support fender bracket.
Background technology
Mining is from the earth's crust and the technology and science of earth's surface exploit mineral resources.The mining of broad sense also includes coal and stone
The exploitation of oil.Mining industry is a kind of important primary industry, and metallic ore is the primary raw material of metallurgy industry, non-metallic ore
It is important industrial chemicals and construction material.The production environment and production process of mining have following compared with other industry
Feature:The primary raw material of digging processing is the ore body of nature preservation.Ore deposit location is unable to unrestricted choice, and the commercial reserves in mineral deposit can not
Input, can not regenerate.The production capacity in mine, the length of service and economic benefit are closely related.Each mine, which will undergo, to be built
Ore deposit, operation, normal production, the underproduction and the course for closing ore deposit.Winning equipment and personnel often shift with mining process and processing object,
The job shop do not fixed.The ore body being produced must tunnel a series of tunnels, carry out mining preparation (adopting standard), ability
Start back production.Open up, adopt accurate and actual mining and coordinate mutually, just can guarantee that mine normally produces.Otherwise it will result in and adopt stripping mistake
Tune or debalance of preparation and winning work, force the mine underproduction.It is that digging condition is more and more poor to exploit the total trend of work, the grade of extracted ore by
Gradually reduce, cost may increase therewith.Because being mixed into for rock can make ore dilution, quality is reduced, also part ore can not
Extraction, and it is lost in underground.Therefore mining and technique of preparing are updated, carries out comprehensive utilization, to reduce cost.Reduce poor
Rate and loss late are quality managements important in mining production, have very big economic potential.Orebody occurrence and
It is complex-shaped, grade skewness.Commercial reserves might have large change in recovery process, mining design is difficult to standard
Change, build ore deposit cycle length in addition, capital expenditure is big, therefore investment risk is also big.Mining activity is in outdoor or underground mining stope.The amount of labour
Greatly, work under hard conditions, security is poor, is not easy to realize comprehensive mechanization and automation, therefore need to especially pay attention to improve labour protection and
Environmental condition.The result of management in one mine, largely it is decided by the market supply and demand and the value height of institute's exploitated ore.
Therefore the evaluation horizontal to mine management, it is impossible to as other industry, be merely defined by absolute economic benefit.Wherein the most
The point that projecting point and people pay attention to the most is that mining works under hard conditions, and security is poor, be not easy to realize comprehensive mechanization and
Automation, in particular for underground mining.The safeguard measure for underground mining essentially consists in construction support fender bracket at present, so
And due to the particularity of underground mining, in order that support fender bracket reaches the protecting effect of requirement, support the intensity of fender bracket must
Certain grade must be reached, so that the weight of support fender bracket is larger.Further, since mining activity is constantly forward movement formula
Working method, thus mining support frame need moved in real time according to mining progress, so due to support fender bracket weight
It is larger so that it moves difficult larger.Movement currently for support fender bracket is, uses the special conscientious branch of mobile device
The towed movement of fender bracket is supportted, but because underground mining space is smaller so that this mode operationally has difficulties, and accounts for
With mining space.
