Description
Technical field
The present invention relates to a kind of mining methods, are based on more particularly, to one kind in exploitation of mineral resources to large diameter, deep borehole barnyard
The method of afterwards filling mining.
Background technology
Mineral products, which refer to all and are imbedded in underground (or being distributed in earth's surface or rock decay or rock deposition), to be available for
The natural minerals or rock resource of human use.Mining industry is that the mankind are engaged in one of ancient field of productive labor.The development of mining industry
Utilization with expanding mineral resources, the development to civilization of human society generate rush that is huge, can not be substituted with progress
Enter effect.The ancestors of the Chinese nation from from them being born, begin to be engaged in mineral exploration and exploitation as many nationalitys in the world
Utilize activity.Human history is divided into the Old Stone Age, the Neolithic Age, the Bronze Age, the Iron Age by historian, all
It is characterized by the Prospecting Target of The Main Minerals species of the utilization of people at that time.Exactly our ancestors reform of nature, the knowledge of natural environment and
During nature remodeling, during finding mineral products, understanding mineral products with utilization mineral products, social productive forces are promoted
Development and the progress of human civilization, certain basis is laid for large-scale Mining Development today.Therefore, in research China's ore deposit
During industry present situation, China's Mining Development history of roughly analyzing and researching first is beneficial.We are at the vast territory of great motherland
The world mankind are born, the vital area of procreation and development.Just lived from the ancestors away from the modern 2,000,000 Nian Qi Chinese nation, work and
Procreation is on this vast soil.To stopping during the Opium War (1840-1842) in 1840 from time immemorial, be Ancient Times in China geological cause and
The rudiment of mining industry, formative year.In this period, ancients are engaged in the exploitation profit of mineral resources under conditions of extremely arduous
With activity, indelible contribution is made that, and is modern age and modern ore deposit for Ancient Times in China civilization, social progress, economic development
Certain basis has been laid in the development of industry.At present, the mineral products about more than 150 for having industrial value in the world are planted, wherein more than 80 kind applications
It is extremely wide.Developed country is the key consumer of world ore resource.Russia, China, Brazil, Australia, India, Canada
The %90 in the world is accounted for U.S.'s iron ore storage capacity.The U.S., Japan, West Europe steel and iron industry are more flourishing, and Japanese iron ore is completely dependent on
Import, Australia, Brazil, Canada are iron ore big export country, and China's output of steel is at the forefront in the world.Mineral Resources in China
Feature is：Species is more, and reserves are big, and the amount of verifying such as tungsten, antimony, rare earth, vanadium and titanium, molybdenum occupies first place in the world, and other ore reserves also occupy
Forefront；Though Iron Ore Reserve is abundant, lean ore is than great；Associated minerals add sorting, the difficulty smelted than great；Skewness,
The more coals in the north, oil, the more non-ferrous metals in south.In exploitation of mineral resources, existing mining methods process is cumbersome, and the effect dug up mine
Rate is low, and collapsing for ore deposit hole easily occurs, and security incident is caused to people.
The content of the invention
It is an object of the invention to overcome above-mentioned existing mining methods process cumbersome, and the efficiency dug up mine is low, and holds
Easily there is collapsing for ore deposit hole, the problem of causing security incident to people, devise a kind of be based in exploitation of mineral resources to major diameter
The method of deep hole open stope afterwards filling mining, this method can improve ore recovery rate, reduce ore dilution rate, make full use of existing
There is resource, effectively control ground pressure and subsidence, the purpose for optimizing mining area surrounding environment, it is numerous to solve existing mining methods process
It is trivial, and the efficiency dug up mine is low, and collapsing for ore deposit hole easily occurs, the problem of causing security incident to people.
The purpose of the present invention is achieved through the following technical solutions：Based in exploitation of mineral resources to large diameter, deep borehole barnyard afterwards
The method of mining with stowing, comprises the following steps：
（1）Nugget is arranged：The vertical ore body arrangement of nugget, mineral building and the wide 15m of ore pillar, length is orebody thickness, fore-set and foundation
Thickness is 5m；
（2）Adopt quasi- cutting engineering：Adopt cut journey mainly undercut tunnel, ore removal wear arteries and veins, drilling chamber, drilling chamber connection roadway,
Return aircourse, dress ore deposit route etc., in mineral building bottom, driving ore removal wears arteries and veins, and wears in arteries and veins to enter to the tunnelling dress ore deposit that undercuts in ore removal
Road, drilling chamber is dug on mineral building top, drilling chamber connection roadway and return air are tunneled respectively along orebody trend in drilling chamber both sides
Tunnel, the tunnel that undercuts is tunneled in mineral building bottom, high 6m is dug on the mineral building mediad of tunnel undercuting, is cut on wide 2m to sector
Groove, fan shaped medium length hole is then beaten upwards from the tunnel that undercuts, along cutting groove explosion by row, ore forms moat ditch formula and undercuted sky after transporting
Between, provide the scope of freedom for ore back production；
（3）Back production and ore removal：Actual mining is divided into rooming and stooping pillaring, during rooming, from drilling chamber in mineral building
The vertical parallel deep hole of major diameter is beaten downwards on top, the ㎜ of blasthole diameter 165, is carried out using the explosive of high density, high explosion velocity, high-power
Explosion, using Uncoincided charge, bore diameter 165mm, coil diameter of getting it filled is 150mm, long 900mm, is implemented by powder charge suitable
Sequence, carries out explosion, the ore of avalanche in bottom by 63 m scrapers through filling ore deposit route, ore removal wears lane and stage transportation roadway directly fills
Main chute is transported to, being then transported to crude ore bin through belt conveyer after crushing cave is broken loads skip bucket, and the back production of ore pillar is in ore deposit
Room back production terminates and filled after maintenance work terminates to carry out；
（4）Filling：It is whole after rolling in mineral building ore, with consolidated fill of casting resin, treat that both sides mineral building has been adopted and used filling
Slurry consolidated fill and after having conserved obturation, the mode back production of ore pillar mineral building back production, is filled, mineral building fills with casting resin afterwards
Fill out and choose Gobi aggregate consolidated fill, Gobi aggregate tailing sand slush is chosen in ore pillar filling.
In summary, the beneficial effects of the invention are as follows：This method can improve ore recovery rate, reduce ore dilution rate,
Existing resource is made full use of, effectively control ground pressure and subsidence, the purpose for optimizing mining area surrounding environment, solve existing mining
Procedure is cumbersome, and the efficiency dug up mine is low, and collapsing for ore deposit hole easily occurs, and asking for security incident is caused to people
Topic.
