Abstract
The invention discloses a building block type constructing method of a standardized prefabricated module of a bottom structure of underground mining. The method includes: designing concrete standardized modules with certain size, shape and strength according to arrangement of a mining scheme; tunneling a drilling passage at a region for arranging the bottom structure, performing drilling explosion in the drilling passage to form a space for constructing the bottom structure, conveying the concrete standardized modules for mounting when the space is formed, and bonding the concrete standardized modules by field concreting or other gelling agents. The method is suitable for various mining methods which need to construct bottom structures. The building block type constructing method has the advantages that complicated fine explosion in rock mass is avoided, safety and efficiency are achieved, process is simple, maintenance is easy, and ore recovery ratio is increased.
Description
Technical field
The present invention relates to a kind of construction method of underground mining polycrystalline substance, particularly relate to a kind of polycrystalline substance standardization Prefabricated block modular construction method that is applicable to the metal mine underground mining.
Background technology
In traditional mining technology, polycrystalline substance generally is to utilize the explosion means in protolith, to form, and its problem of facing is that complex procedures, efficient are low, difficult forming, poor stability, and in use as occur destroying and then be difficult to maintenance.Simultaneously,, reclaim difficulty, cause ore loss ratio high, bring very big economic loss because polycrystalline substance presses the ore deposit amount big.
Summary of the invention
Technical problem to be solved by this invention is to propose a kind of need not in rock mass, to carry out complicated meticulous explosion, and operation is simple, safe and efficient, the underground mining polycrystalline substance standardization Prefabricated block modular construction method of easy-maintaining and raising ore recovery ratio.
In order to solve the problems of the technologies described above, underground mining polycrystalline substance standardization Prefabricated block modular construction method provided by the invention according to the deployment scenarios of mining scheme, designs the concrete standard module of certain size, shape and intensity; Rock drilling route of driving in arranging the zone of polycrystalline substance; In the rock drilling route, carry out driling explosion then; Form a space of constructing polycrystalline substance; After this space forms, transport the concrete standard module and install, adopt poured in place concrete or other gelling agents bonding between the concrete standard module.
Polycrystalline substance to moat ditch form; At first tunneling a specification in the stope bottom along its length direction is the rock drilling route about 3m * 3m; The cutter up-hole carries out explosion in the rock drilling route then, thereby forms the space of a rectangular shape on rock drilling route top, and this space is carries out the space that the moat groove structure is constructed; After constructing the space and forming; Promptly by plan prefabricated concrete standard module is carried out building block system and install, the concrete standard module is built completion on ground in advance, adopts concrete or other glue gels bonding between the concrete standard module and between concrete standard module and the country rock; To the polycrystalline substance of funnel form, it constructs the space is cylindrical.
In the polycrystalline substance use, damage as finding the somewhere, directly the corresponding standard module is replaced, need not to construct fully again or discard.
In the rock drilling route, carry out driling explosion, form a space of constructing polycrystalline substance.This spatial altitude should be than the big 1～2m of polycrystalline substance of design.
Adopt the underground mining polycrystalline substance standardization Prefabricated block modular construction method of technique scheme, the invention has the beneficial effects as follows, ready-made standardized module is transported to the scene and installs in advance, has greatly improved the efficient of constructing of polycrystalline substance; Reduced the technical difficulty of on-the-spot meticulous explosion; Reduce the working time of workman in exposed space, improved safety; Polycrystalline substance can not pressed the ore deposit, has improved the rate of recovery of ore.Simultaneously, this polycrystalline substance good stability, receive ore faces long-pending big, the ore removal job safety.
In sum, the present invention is that a kind of need not carried out complicated meticulous explosion in rock mass, and operation is simple, safe and efficient, the underground mining polycrystalline substance standardization Prefabricated block modular construction method of easy-maintaining and raising ore recovery ratio.

The specific embodiment
Below according to accompanying drawing and combine the specific embodiment that the present invention is described further.
To shown in Figure 5, to the polycrystalline substance of moat ditch form, at first tunneling a specification in the stope bottom along its length direction is the rock drilling route 2 about 3m * 3m like Fig. 1; The cutter up-hole carries out explosion in rock drilling route 2 then, thereby forms the space of a rectangular shape on rock drilling route 2 tops, and this space is carries out the moat groove structure and construct the space, the height in this space should be than the height of design bottom structure big 1～2m.After constructing the space and forming, can prefabricated concrete standard module 3 be carried out building block system by plan and install, concrete standard module 3 is built completion on ground in advance; Adopt concrete or other glue gels bonding between the concrete standard module 3 and between concrete standard module 3 and the country rock 2.
The polycrystalline substance of funnel form is constructed process such as Fig. 6 to shown in Figure 9, and it constructs mode and moat ditch bottom structure, and to construct mode similar, the main distinction is that explosion forms construct the space with cylindrical be good, and the country rock between adjacent funnel is advisable not destroy.
In the polycrystalline substance use, get final product as finding the somewhere damage, can directly the corresponding standard module being replaced, need not to construct fully again or discard.
