Description
Technical Field
The invention relates to the technical field of underground mining and filling of metal mines, in particular to a slope ramp arrangement method applied to an upward layered filling mining method stope.
Background
In the practical process of the upward stratified filling mining method in the metal mine, along with the application and popularization of the scraper, the mine shoveling operation and the tunneling slag discharging operation efficiency of the stope are greatly improved, and the labor intensity and the operation environment are obviously improved. However, as a large-scale mechanical device, in order to facilitate the entry and exit of a scraper and larger parts into and out of a stope, a slope is generally constructed in stable rocks on one side of the stope to penetrate through an upper horizontal middle roadway and a lower horizontal middle roadway as a main mining-preparation engineering content. And meanwhile, when the layer is changed in the stope, a layer-changing connection channel needs to be constructed again or the waste rocks specially mined are specially piled up in the layer-changing slope way. The typical ramp way arrangement method has the characteristics of large tunneling engineering quantity, high tunneling-mining ratio, complex tunneling and deslagging procedures, high waste rock transferring and filling cost and the like, and when the waste rocks are lifted out of a well, the waste rock conveying and filling method does not accord with the concept of non-waste mining and is not beneficial to controlling the production cost. How to reduce the tunneling engineering amount to the maximum extent, reduce the tunneling-mining ratio and realize the in-situ filling of tunneling waste rocks while meeting the requirements of the scraper on walking and overall mining accuracy is a problem to be solved urgently.

In order to achieve the technical purpose, the technical scheme adopted by the invention is as follows:

constructing the slope ramp section by section along with the rise of the layered stoping of the stope until the slope ramp penetrates through the upper horizontal middle section roadway;
the slope way is used as a safety channel and a layer transfer channel of a scraper when the stope is used for layered stoping, and the slope way is used as a main slope way between an upper horizontal middle section roadway and a lower horizontal middle section roadway after the stope is used for layered stoping.
As a further improved technical scheme of the invention, when an upward layered filling mining method is adopted to stope an ore body, a return type slope way is dug upwards from a lower horizontal middle section roadway at a position which is close to the boundary of the ore body or 5-10 meters of the stope boundary on one side of a stope, and the slope of the slope way is less than 20%.
As a further improved technical scheme of the invention, the slope way is constructed section by section along with the rise of the stope layered stope, and the tunneling height of the slope way is always ahead of the height of the stope layered stope of the production stope, rather than penetrating through the upper horizontal middle roadway and the lower horizontal middle roadway at one time; the ramp is turned back between two adjacent stopes, and the ramp is turned back once every 3 layered heights is raised until the ramp penetrates through the upper horizontal middle section roadway.
As a further improved technical scheme of the invention, a manway, an ore pass and a filling return air shaft are arranged in the stope, a slope way is communicated with each layer of stope recovery by a short communication way, and the filling return air shaft in the stope is used as a temporary ventilation shaft for ventilation operation.
As a further improved technical scheme of the invention, the waste rocks during the tunneling of the slope way are transported to the goaf of the layered stope nearby by the scraper, and the transported waste rocks are used for piling a transfer layer connecting road between two adjacent stopes or filling the goaf.
The invention has the beneficial effects that: the invention provides a novel method for arranging a slope way for an upward cut-and-fill stope, which saves larger tunneling engineering amount such as a sublevel drift and the like by arranging the slope way in an area close to an ore body and constructing section by section, can reduce the tunneling-mining ratio and the production cost, can well solve the problem of nearby filling of the waste rocks tunneled by the slope way and an interconnecting road, avoids inefficient transfer and lifting of the waste rocks out of a well, and has important significance for realizing energy-saving and environment-friendly treatment of the tunneling waste rocks. When the slope ramp is used as the content of the stope mining preparation scheme, facilities such as a waste rock chute, a chute yard, related connecting roads, a sectional drift waste rock chute, a yard and a sectional drift temporary air shaft of the slope ramp do not need to be constructed.

(2) The slope 4 is constructed section by section along with the rise of the layered stope mining of the stope until the slope penetrates through the upper horizontal middle roadway 7; the slope ramp 4 is used as one of safety channels of the stope and a layer transfer channel of the scraper when the stope is used for layered stope, and the slope ramp 4 is used as a main slope ramp between an upper horizontal middle roadway 7 and a lower horizontal middle roadway 6 after the stope is used for layered stope.
(3) The slope 4 is constructed section by section, and the tunneling height is always ahead of the height of the stoping layer of the production stope, instead of penetrating through the upper horizontal middle roadway 7 and the lower horizontal middle roadway 6 at one time; meanwhile, the ramp 4 is always turned back between two adjacent stopes, and the ramp 4 is turned back once every 3 layered heights rises until the ramp penetrates through the upper horizontal middle section roadway 7.

And the waste rocks generated during the tunneling of the slope 4 are transported to the goaf of the layered stope nearby by the scraper, and the transported waste rocks are used for piling a transfer layer connecting passage between two adjacent stopes or filling the goaf.
(5) Before filling, a stope communicated with the ramp 4 needs to build a filling retaining wall in the short connecting channel 5 close to one side of the ramp 4, isolate the stope (including the short connecting channel 5) from the ramp 4, fill the stope and the short connecting channel 5 synchronously, and permanently reserve the ramp 4 to be used as a subsequent main ramp. As can be seen from fig. 2, the short communication duct 5 of the stope level located below the 5 th level (the level communicated with the short communication duct 5 at B in fig. 2) is filled up at the time of production to the 8 th level (the level communicated with the short communication duct 5 at a in fig. 2), and cannot be seen, and only the single ramp 4 can be seen.
(6) If necessary, anchor rod (net) support or anchor (net) spraying support is carried out in the slope 4 so as to ensure the stability of the top plate and two sides of the slope 4.
