Abstract
The utility model relates to the technical field of mining, in particular to short pass type united mining equipment. The short pass type united mining equipment comprises a top plate supporting and protecting mechanism and a base plate supporting and protecting mechanism, wherein top plate supporting and protecting mechanism comprises a blast hole and a top plate filling body; the base plate supporting and protecting mechanism comprises a base plate filling body, a false bottom, ore removal short passes, an ore removal heading and an ore pass; the blast hole is communicated with the top plate filling body and the base plate filling body. With the increase of the mining depth, a caving region is formed; a goaf region is fully filled by increasing the amount of the filling bodies; due to the top plate filling body and the base plate filling body, the stress conduction is reduced, and the mine ground pressure is effectively controlled. Furthermore, steel ribs are overlapped with the false bottom to isolate the caving region from a working region, so that construction is facilitated, and the safety is guaranteed. The false bottom is communicated with the ore removal heading through the ore removal short passes; the ore short pass has a hollow structure; the ore removal short passes can achieve an extremely good supporting and fixing effect; the stability of a mine is obviously improved; a worker is safe and works efficiently when removing ores in the ore removal short passes.
Description
Technical field
The utility model relates to the mining technical field, particularly a kind of short formula combined mining equipment of wearing.
Background technology
The mine structure is divided into armor rock and ore body lower wall country rock on ore body, and wherein on ore body, the armor rock mostly is the zone of fracture rock group that phyllite and chlorite schist form, the across pitch joints development, and poor stability, need supporting in digging; The silication of ore body lower wall country rock is strong, and the joint agensis is medium-hard rock, more stable.Zone of fracture rock group is mainly the quartz albitophyresi of lower wall and the contact zones of quartzy angle spot tuff, and the steadiness of this rock zone is poor, and wall caving, roof fall, the phenomenon that collapses are common.Along with security incident can usually occur in high-risk status in the intensification ore body of mining depth, compose the high ore body of high-grade, industrial value of depositing the even waste treatment that lies on the table because security reason is a lot, all brought great loss to mine and exploitation unit.
Particularly, in the little Tie Shan of silver ore deposit, the grade of ore of east stope Hanging orebody is high, and industrial value is high, but the inbreak location is more, belongs to uneasily mining orebody.The grade of ore of western stope Hanging orebody is up to 30% left and right, the ore body joints development, and two help steadiness poor, and usually built on the sand, the inbreak phenomenon often occurs in top board, also belongs to uneasily mining orebody for filling false bottom reason but the utmost point.Normal back production is difficult to by inbreak location or not guarantee of secure context, and loss ore deposit amount is very large, causes full ore deposit grade low.In order to coil the high-grade ore body in back production as far as possible, reduce loss of mineral resources, adopt short the wearing in back production of route associating to coil the high-grade ore body.
The utility model content
The purpose of this utility model is to provide a kind of stable, a kind of short formula combined mining equipment of wearing that production efficiency is high easy to use, safe.
The utility model solves the technical scheme that its technical problem adopts:
A kind of short formula combined mining equipment of wearing, comprise dish supporting mechanism and lower wall supporting mechanism, described upper dish supporting mechanism comprises big gun hole and upper dish obturator, described lower wall supporting mechanism comprises that lower wall obturator, the false end, ore removal are shortly worn, ore removal gallery and ore pass, and the big gun hole is communicated with upper dish obturator and lower wall obturator.
The described false end, be communicated with by short the wearing with the ore removal gallery of ore removal, and short the wearing of ore removal is at least one.
Described ore removal is short to be worn as hollow structure.
The described false end, adopt bar splicing.
Top board obturator of the present utility model and base plate obturator can all play support action to upper and lower armor rock, along with the increase of mining depth there will be goaf, increase obturator quantity is filled up the goaf domain space and is got final product, top board obturator and base plate obturator reduce the conduction of stress, effectively control rock pressure.Adopt the false end of bar splicing, by inbreak zone and working region isolation, convenient construction has also guaranteed safety simultaneously.The ore gathered is deposited at false the end, by short the wearing with the ore removal gallery of ore removal, be communicated with, ore deposit is short wears as hollow structure, can set up according to ore reserve that ore removal is short to be worn, short the wearing of ore removal can be played good support fixation, the stable mine solidity significantly promotes, and the workman carries out the ore removal operation in wearing ore removal is short, more safe and efficient.
The accompanying drawing explanation
Fig. 1 is roof timbering mechanism structure schematic diagram of the present utility model;
Fig. 2 is base plate supporting of the present utility model mechanism structural representation.
The specific embodiment
A kind of short formula combined mining equipment of wearing as depicted in figs. 1 and 2, comprise roof timbering mechanism and base plate supporting mechanism, described roof timbering mechanism comprises big gun hole 1 and top board obturator 2, described base plate supporting mechanism comprises that base plate obturator 3, the false end 4, ore removal shortly wear 5, ore removal gallery 6 and ore pass 7, and big gun hole 1 is communicated with top board obturator 2 and base plate obturator 3.The described false ends 4, adopt bar splicing, and wear 5 and is communicated with ore removal gallery 6 by ore removal is short at the false end 4, and ore removal is short, and to wear 5 be hollow structure, and ore removal is short to be worn 5 and be at least one.
During use, according to Zha Chubao hole, mineral reserve position 1, adopt the false end 4 of bar splicing, bar diameter is 20mm, be overlapped to form the grid of 250*250mm, bottom ore removal of the false ends 4 is short to be worn 5 and is communicated with ore removal gallery 6, top board obturator 2 and base plate obturator 3 are filled in top, the false ends 4, ore 8 is from the interior derivation in big gun hole 1, ore 8 passes top board obturator 2 and base plate obturator 3,, fall and be deposited on the grid at the false end 4, the workman imports ore removal gallery 6 in short 5 work of wearing of ore removal by ore 8, finally the ore in ore removal gallery 6 is imported to ore pass 7 and transports.Along with going deep into of mining, there will be territory, goaf 9, use top board obturator 2 and base plate obturator 3 to fill and can meet construction requirement.
