Abstract

The invention discloses a high-dipping medium thick ore body mining method. Filling is executed in an upward horizontal segmental manner. A middle section of an ore body is divided into five segmental flat alleys (1) according to a vertical height direction; a steel wire rope and a pipe seam anchoring rod are arranged in a goaf of a first segmental flat alley (1-1) of the middle section; a paste body, which is formed by adding cement into concrete C25 or tailings and serves as a cemented filling body (4), is used for filling the goaf; dry-type filling bodies (3) are filled in second, third, fourth and fifth segmental flat alleys (1-2, 1-3, 1-4 and 1-5) of the middle section; a studding (5) reserved in a mining field is replaced by an artificial rubble concrete supporting column (6). The high-dipping medium thick ore body mining method is simple in construction, and can be used for effectively improving the ore recovery rate and the safety and reliability of a mining field.

Description

A kind of high-dipping middle thickness orebody mining methods

Technical field

The present invention relates to a kind of mining methods, especially on high-dipping middle thickness orebody to formula horizontal fragmentation filling method.

Background technology

High-dipping middle thickness orebody is dug up mine, and sublevel open stope method and the dry filling method of adopting carries out back production more always, and each stage casing of sublevel open stope method, segmentation need be stayed and establish a large amount of fore-sets, studding, and poor stability; Dry filling method stope all adopts rubble dry stowing, and protect top in order to ensure withstanding during lower stage casing back production, each stage casing at least needs the ore bed of a loss segmentation, ore recovery rate is low, and dry stowing can not make goaf filling connect top, filling effect is poor, and security reliability is poor.

Summary of the invention

The technical problem to be solved in the present invention is: provide a kind of high-dipping middle thickness orebody mining methods, the effective ore recovery rate improving stope, and guarantees that Stope safty is reliable.

Technical scheme of the present invention is: a kind of high-dipping middle thickness orebody mining methods, to the filling of formula horizontal fragmentation on adopting, first according to vertical height, stope is divided into multiple stage casing, is then divided into five slice drifts by vertical height in each stage casing, from the first slice drift, upwards exploit piecemeal; After first sub-level drift stoping in this stage casing terminates, in the first slice drift goaf, arrange wire rope and pipe seam anchor bar, close stope and import and export, then lotion C25 concrete or tailings being added cement production systD is fills up to goaf as cemented fill; Stage casing second and third, four, five slice drifts all adopt dry-placed fill filling.

The vertical height of the slice drift in described high-dipping middle thickness orebody mining methods is equal, and is 12 meters.

During back production, the studding first in back production dry stowing stope, namely first back production second and third, four, studding in five slice drift stopes, then build the artificial shore supports goaf of rubble concrete by laying bricks or stones.

The filling method that the present invention adopts dry stowing and consolidated fill to combine to underground goaf, construction is simple, and stope is safer, and reliability is higher.The cemented fill of the first slice drift, as Man-made False during next stage casing stope mining, avoids the ore bed of a loss segmentation.Stay the studding established to adopt the artificial pillar of rubble concrete to replace to stope, effectively improve ore recovery rate.

Accompanying drawing explanation

Fig. 1 is ore body structural representation of the present invention;

Fig. 2 is section A-A schematic diagram.

Detailed description of the invention

As shown in Figure 1, a kind of high-dipping middle thickness orebody mining methods, to the filling of formula horizontal fragmentation on adopting.In stope, ore body 7 is divided into a stage casing according to 60 meter Chui Gao, is divided into five slice drifts 1 in this stage casing by vertical height 12 meters.Slice drift 1 is arranged in bed top 15 meters of along ore bed, adopts accurate ramp 2 and is arranged in bed top 40 meters of.

After the first slice drift 1-1 back production in stage casing terminates, arrange wire rope and pipe seam anchor bar in the first slice drift 1-1 goaf after, close stope and import and export, C25 concrete is fills up to goaf as cemented fill 4.The cemented fill 4 of the first slice drift 1-1 in this stage casing is as Man-made False during next stage casing stope mining.In stage casing second and third, four, five slice drift 1-2 ~ 1-5 all adopt dry-placed fill 3 filling, the stope of dry stowing, first stope is entered by the construction crossdrift of the slice drift 1 of bed top, studding 5 reserved in first back production stope after entering stope, build the artificial pillar 6 of rubble concrete after studding 5 back production by laying bricks or stones and support goaf top plate, after the ore of rooming again.

Claims (3)
