Description

Truck cooperates with ore removal sublevel drilling block chambering method
Technical field
The present invention relates to a kind of mining methods of metal mine underground mining, specifically a kind of truck collaboration ore removal segmentation chisel Rock block chambering method, it is adaptable to the thready pulse that the firm thick and extremely thick high-dipping ore block of ore-rock or the parallel extra narrow vein of high-dipping are constituted The exploitation of band.
Background technology
The thready pulse band that the parallel extra narrow vein of the thick and extremely thick high-dipping ore block or high-dipping that are consolidated for ore-rock is constituted, typically Ore deposit block chambering method back production, vertical long hole sublevel drilling rank are fallen using vertical long hole sublevel drilling block chambering method and horizontal deep hole Section mineral building method back production ore body has mining rate big, and ventilation condition is good, the advantages of mineral building production capacity is big, but due to using electricity The ore removals such as rake, drop shaft, exist to adopt to a certain extent and cut that quantities is big, the low shortcoming of ore removal efficiency.Horizontal deep hole falls the ore deposit stage Mineral building method back production ore body has labor productivity high, the low advantage of mining cost, but has one to polycrystalline substance when there is ore caving The shortcomings of fixed destructiveness.
In recent years, the trend that mining link and flexible transport are China's underground mine production technique development is simplified, Under the guidance of collaboration exploitation mining technical concept, secondary innovation is carried out to traditional sublevel drilling block chambering method, it will help In ensureing to fall the collaboration of ore deposit and ore removal operation on time and ore deposit amount, the production efficiency in mine is lifted.
The content of the invention
The shortcoming that the present invention is directed to traditional sublevel drilling block chambering method cooperates with ore removal sublevel drilling there is provided a kind of truck Block chambering method.This method uses truck and the direct ore removal of ramp, improves mechanization degree, improves ore deposit and ore removal Harmony.And polycrystalline substance is simplified, reduce ore transhipment cargo handling operation and Cai Qie quantities.Stoping strength is increased, it is raw Yield is greatly improved, and finally realizes safe efficient, the inexpensive collaboration back production of ore body.
To solve above-mentioned technical barrier, the technical solution adopted by the present invention is:A kind of truck cooperates with ore removal sublevel drilling rank Section mineral building method, comprises the following steps:
(1) the thready pulse band division of the parallel extra narrow vein composition of the thick and extremely thick high-dipping ore block or high-dipping that consolidate ore-rock Nugget is divided in stage, stage, nugget is divided into mineral building and ore pillar, several segmentations are highly divided into along mineral building;
(2) before mineral building back production, drawing chute, short drop shaft is constructed in bottom using haulage drift, way shaft of divulging information is utilized Sublevel drilling tunnel is constructed, and slot raise expansion side is dug by drilling drift and forms cutting groove;
(3) during mineral building back production, stamped in sublevel drilling tunnel to fan shaped medium length hole, upper advanced two artillery salvos hole of segmentation is adopted With the artillery salvo hole ore caving of elementary errors segment blast 3~5, the ore of avalanche is directly loadable into through short drop shaft and drawing chute under gravity Truck, truck is transported to earth's surface through ramp, until mineral building back production is finished.
The thready pulse band division of the firm thick and extremely thick high-dipping ore block of the ore-rock or the parallel extra narrow vein composition of high-dipping Nugget is divided in stage, stage, nugget is divided into mineral building and ore pillar, and stage high 50~60m is highly divided into several along mineral building Segmentation, is segmented high 10~12m, mineral building 30~50m of length, the wide 8~10m of studding, 5~6m of fore-set thickness.
The thready pulse band division of the firm thick and extremely thick high-dipping ore block of the ore-rock or the parallel extra narrow vein composition of high-dipping Nugget is divided in stage, stage, nugget is divided into mineral building and ore pillar, several segmentations are highly divided into along mineral building, including it is as follows Step:
It is the short drop shaft that 4m × 3.5m haulage drifts dig 3m × 2m using specification, 2m × 2m ventilation people's rows is arranged in studding Courtyard, using this upraise 3m × 3m sublevel drillings tunnel, and it is the expansion of 2m × 2m slot raises to dig specification by drilling drift Side forms cutting groove, is stamped in drilling drift to fan shaped medium length hole, and inner side blasthole and level are at least into 55 °, so as to ore profit Glided with deadweight, upper advanced two artillery salvos hole of segmentation, using the artillery salvo hole ore caving of elementary errors segment blast 3~5, drawing chute mouthful, which is installed, to shake Dynamic ore drawing machine, and ore drawing machine goes out mine mouth end apart from roadway floor at least 2.5m, the ore of avalanche is through short drop shaft and drawing chute Truck is directly loadable into, truck is transported to earth's surface through specification for 3m × 3m ramp, until mineral building back production is finished.
The ramp gradient is 10%~15%, and the ramp turn of bilge gradient is 0~3%.
The ramp is two-way traffic with haulage drift joint, meets empty wagons and the current requirement side by side of fully loaded car.
The present invention protrusion technical characterstic be:
(1) overcome that conventional segmented rock drilling block chambering method ore removal efficiency is low, adopts and cuts the big shortcoming of quantities, improve life Efficiency is produced, reduces to adopt and cuts quantities.
(2) truck and the direct ore removal of ramp are used, mechanization degree is improved.
(3) polycrystalline substance is simplified, ore transhipment cargo handling operation is reduced.
(4) stoping strength is big, and productivity ratio is greatly improved, and stoping operation is safer.
