Description
Technical field
The present invention relates to mining technical field, and in particular in a kind of high stratification mechanization suitable for underground mine
To stoping method.
Background technology
Mining refers to the method for the extracted ore from nugget, including adopts three work such as accurate, cutting and back production.Back production be from
Complete to adopt standard, cut the process of extracted ore in the nugget of work.Process for stoping includes falling 3 kinds of ore deposit, ore removal and underground pressure management works
Industry.
Existing mechanization Upward slicing process for stoping includes rock drilling, charge explosion, turquoise processing, ore removal, stope filling
Etc. link.Wherein, rock drilling is to carry out Drilling to rock mass to arrange up-hole hole pattern；Charge explosion is recurred toward powder charge in blasthole
Quick-fried blasthole hole pattern；Turquoise processing refers to after one is layered stope explosion, is manually entered processing top plate and highwall turquoise in stope,
Ensure top plate and slope safety；Ore removal is to carry out ore out of stope；Stope filling is used after Slice stoping ore removal
Fine cementing or tailing cemented filling, packed height are layering Blasting height, retain certain altitude as lower secondary clearing explosion
Compensation space and equipment availability space, body to be filled reach the stoping operation that next layering can be carried out after intensity.
Existing common mechanization Upward slicing stoping method is in order to control Stope roof and highwall, it usually needs will return
Mining height degree is limited in below 3.6m, and outage is only in below 8.5m after back production, therefore mining efficiency is than relatively low, and ore removal is made every time
It is both needed to manually carry out turquoise processing before industry, greatly threatens the personal safety of operating personnel.
As the constantly increase of scale and being continuously increased for mining rate and mining depth, underground are integrally exploited in mine
Safety production condition also worse and worse, the safety in production pressure that stoping operation faces also increasingly increases.Especially for scale
For huge and poor structure top, pillar Stope, existing common mechanization Upward slicing stoping method can not meet ore deposit
The needs of mountain production, it is therefore necessary to be improved to existing process for stoping, peace could be realized while production task is completed
Full production.
The content of the invention
Based on this, it is an object of the present invention to provide a kind of high stratification mechanization raise mining method, it is with back production height
Degree is big, mining efficiency is high, can effectively improve the advantages of security reliability of stoping operation.
The technical solution adopted by the present invention is as follows：
A kind of high stratification mechanization raise mining method, including the step of drilling arrangement, ore caving and ore removal,
The drilling is arranged as：The central area of stope is first divided into slotting area, then will surround the region in slotting area
Auxiliary region is divided into, and slotting area and auxiliary region is equal to Width of stope along the total length in length of stope direction, then by stope
Region division beyond slotting area and auxiliary region is Ce Beng areas；Then, 9 hole depths of center arrangement in slotting area are not less than 5.4m
Centre cut hole, wherein powder charge in 5 centre cut holes, remaining 4 centre cut hole is the emptying aperture of not powder charge, then this 9
Multiple keyholes of inside and outside two circle of peripheral disposition composition in a centre cut hole, and toward powder charge in each keyhole；In auxiliary region
Interior arrangement multiple via holes composition hole patterns, and toward powder charge in each via hole；Arrange that multiple sides collapse hole composition hole in Ce Beng areas
Net, and collapse powder charge in hole toward each side；
The ore caving is：Collapsed according to the centre cut hole in slotting area, the keyhole in slotting area, the via hole of auxiliary region, side
The firing order progress explosion that the side in area collapses hole falls ore deposit.
Stoping method of the present invention is rationally designed by being arranged to the blasthole hole pattern in stope, especially by
The blasthole Hole pattern parameters in slotting area are optimized, are needed to set the keyhole of suitable number according to explosion, and arrange and do not fill
The scope of freedom when emptying aperture of medicine is as explosion, the comprehensive stability for improving rock stratum in whole exploitation process.By Stope test,
Uniform using ore fragmentation after the stoping method explosion, Stope roof is more smooth, and the protection to highwall preferably, without obvious is broken
It is bad, therefore manually upper ore deposit heap progress turquoise can be reduced and handle this dangerous larger operation procedure, realize efficient mechanization
Production.Furthermore back production is highly increased to more than 5.4m by the stoping method, make after disposable back production outage more than 8.5m, greatly
It is big to improve mining efficiency, and by increasing apart from unstable formation and the entity stoping width of obturation, can effectively improve
Security reliability during whole rock drilling, avoids operating personnel in fractured rock, real apart from top stage casing or first floor obturation
Rock drilling when body thickness is smaller, avoids ore-rock accident inbreak from caving in hurting people or smashing objects.
Relative to existing common mechanization Upward slicing stoping method, the mining efficiency of stoping method of the invention is more
Height, security reliability higher, operation are simpler, and existing equipment and material can be used directly, without buying large-scale set again
It is standby, it is only necessary to the more bit change when constructing slotting area, and without being giveed training again to operating personnel, improving cost is low.The present invention
Stoping method be particularly suitable for the poor top of structure, pillar Stope, back production can highly be increased to 7.2m, then disposable back production
Outage can reach 9m~12m afterwards, greatly improve production efficiency.
