Description
Technical field
This utility model belongs to sub-terrain mines filling method two step back production nugget structure field, relates to a kind of filling method two step back production nugget post wall combination type structure.
Background technology
When sub-terrain mines filling method two step back production, a step mining blocks and two step mining blocks interval are arranged, current structural form mainly has two kinds, and one is wall structure；Another kind is pillar structure, is respectively used to different conditions.The nugget side exposed area of wall structure is relatively big, is mainly used in the mine that ore deposit rock relatively consolidates, and efficiency is higher；Pillar structure is mainly used in the mine that ore-rock stability is slightly worse, and efficiency is slightly lower.There is presently no a kind of desired configuration form, can be not only used for the mine that ore-rock stability is slightly worse, higher efficiency to be obtained again.
Thus, this utility model provides a kind of post wall combination type structure, can either be used for the mine that ore-rock stability is slightly worse, can obtaining again higher efficiency.
Summary of the invention
The purpose of this utility model is to provide a kind of structural form, can either be used for the mine that ore-rock stability is slightly worse, can obtaining again higher efficiency.
One step mining blocks of this utility model a kind of filling method two step back production nugget post wall combination type structure uses pillar structure, two step mining blocks use wall structure, one step mining blocks is made up of the pillar nugget of multiple independent back production, the pillar nugget of multiple independent back production is rods arranged in horizontal line, adopting wall nugget with two steps parallel, interval is arranged；Discharging tunnel is arranged in the side bottom two step mining blocks, so as the Ore of ore removal equipment shipment opposite side collection ore deposit funnel bottom, the dress ore deposit route being connected with discharging tunnel, in addition to leading to this two steps mining blocks collection ore deposit funnel bottom, is also open into an adjacent step and adopts the bottom of pillar nugget collection ore deposit funnel；Lead to haulage drift in one end of discharging tunnel, and the other end leads to return aircourse, fresh distinguished and admirable by haulage drift entrance discharging tunnel, then enters return aircourse from discharging tunnel；Drop shaft is arranged near haulage drift, is communicated with haulage drift by drop shaft connecting taxiway；Collect bottom nugget and in the middle part of the funnel of ore deposit, upwards arrange that cutting well is to nugget top, in collection ore deposit funnel bottom upwards, in dress ore deposit route corresponding to adjacent back production stage casing, top and discharging tunnel, arrange downwards big gun hole, in nugget, the Ore of avalanche uses carrier loader to be transported to drop shaft transferred to collective conveyance level by dress ore deposit route, discharging tunnel, haulage drift, drop shaft connecting taxiway in collection ore deposit funnel bottom；During back production, first adopt a step mining blocks, two step mining blocks are exploited after both sides one step mining blocks complete extraction filling maintenance terminates again, after funnel top, nugget Zhong Ji ore deposit ore body has been adopted, gather remaining ore body in the following nugget of ore deposit funnel again, remaining ore body beats shot hole blasting in dress ore deposit route, discharging tunnel, and the Ore of avalanche uses remote control carrier loader to transport.
In this utility model, a step mining blocks uses every one adopting one, adopting one every two and adopt one every three according to the steadiness of ore body, and the preferable ore body of steadiness uses and adopts one every one, and the slightly worse ore body of steadiness adopts one every two, and the poorest ore body of steadiness uses adopts one every three.
In this utility model, a step adopts pillar nugget except using in addition to positive tetrahedron, consolidates situation also according to ore body and uses other polyhedral structures, uses circular configuration when steadiness is poor；Collect ore deposit funnel bottom nugget and can also use moat ditch or flat-bottom structure.
When ore body upper lower burrs country rock steadiness is poor, adopts wall nugget in two steps and contact with upper lower burrs country rock and increase by a step at band and adopt pillar nugget, consolidated fill, two steps are adopted wall nugget and cuts off with unsteady country rock.
Structural form of the present utility model is the structural form in exploitation process, belongs to dynamic construction form, after back production terminates, and final total structure genomorph wall structure.
This utility model is compared with the most single wall structure or pillar structure, and a step adopts the pillar nugget scope of application relatively greatly, and two steps are adopted wall nugget and adopted exploitation in the middle of consolidated fill, the preferable nugget of steadiness in a step, safe and efficient.

Detailed description of the invention
See Fig. 1～Fig. 4, one step mining blocks 11～18 of this utility model a kind of filling method two step back production nugget post wall combination type structure uses pillar structure, two step mining blocks 21,22 use wall structure, one step mining blocks 11～18 is made up of the pillar nugget of multiple independent back production, the pillar nugget of multiple independent back production is rods arranged in horizontal line, adopting wall nugget 21,22 with two steps parallel, interval is arranged；Discharging tunnel 33 is arranged in the side bottom two step mining blocks 21,22, so as the Ore bottom ore removal equipment shipment opposite side collection ore deposit funnel 19, the dress ore deposit route 32 being connected with discharging tunnel 33, in addition to leading to bottom this two steps mining blocks 21,22 collection ore deposit funnel 19, it is also open into an adjacent step and adopts the bottom of pillar nugget 11～18 collection ore deposit funnel 19；Haulage drift 34 is led in one end of discharging tunnel 33, and the other end leads to return aircourse 37, fresh distinguished and admirable enters discharging tunnel 33 by haulage drift 34, then enters return aircourse 37 from discharging tunnel 33；Drop shaft 36 is arranged near haulage drift 34, is communicated with haulage drift 34 by drop shaft connecting taxiway 35；Collect bottom nugget and in the middle part of ore deposit funnel 19, upwards arrange cutting well 31 to nugget top, in collection ore deposit funnel 19 bottom up, arranging downwards big gun hole 41 in dress ore deposit route 32 corresponding to adjacent back production stage casing, top and discharging tunnel 33, the Ore 42 of avalanche in nugget uses carrier loader to be transported to drop shaft 36 transferred to collective conveyance level by dress ore deposit route 32, discharging tunnel 33, haulage drift 34, drop shaft connecting taxiway 35 bottom collection ore deposit funnel 19；During back production, first adopt a step mining blocks 11～18, two step mining blocks 21,22 are exploited after both sides one step mining blocks 11～18 complete extraction filling maintenance terminates again, after funnel 19 top, nugget Zhong Ji ore deposit ore body has been adopted, gather remaining ore body in ore deposit funnel less than 19 nugget again, remaining ore body beats shot hole blasting in dress ore deposit route 32, discharging tunnel 33, and the Ore of avalanche uses remote control carrier loader to transport.
In this utility model, a step mining blocks 11～18 uses according to the steadiness of ore body and adopts one (as first adopted 11,13,15,17 every one, after adopt 12,14,16,18), adopt one (as first adopted 11,14,15,18 every two, after adopt 12,16, finally adopt 13,17 again) and adopt one (when a step mining blocks number is less than or equal to 4 every three, the nugget number of back production simultaneously is 1), the preferable ore body of steadiness uses and adopts one every one, and the slightly worse ore body of steadiness adopts one every two, and the poorest ore body of steadiness uses adopts one every three.
