Description

Middle thickness low-angle dip breaking ore body mineral building pillar filling-up method
Technical field
The invention belongs to metalliferous deposit underground mining methods technical field, and in particular on middle thickness low-angle dip breaking ore body to Horizontal cut and fill stoping.
Background technology
The exploitation of low-angle dip breaking ore body is always the problem of underground mining method, does not all find safely and effectively adopt always Ore deposit method, in addition ore body crush, more increase ore body back production difficulty.Traditional mining methods have room and pillar stoping, filling to adopt The mining methods such as ore deposit method, breasting method mining codes, these mining methods for thin, very thin low-angle dip consolidate orebody mining effect compared with It is good but not good enough for middle thick low-angle dip breaking ore body exploitation effect above.
The content of the invention
Nugget is divided into several stalls it is an object of the invention to provide one kind, if being further subdivided into panel A dry stope, the middle thick low-angle dip breaking ore body upward horizontal slice mining with stowing that the back production in whole panel is completed suddenly in two steps Method.
To achieve the above object, the present invention provides following technical solution:
Middle thickness low-angle dip breaking ore body filling-up method, the mining codes carry out as steps described below:
(a)Ramp is arranged in the upper disk of ore body, ramp is crossed with each segmentation ore removal to be connected, and ramp is scraper first Machine and the walking passageway of personnel;
(b)Each stope is divided five to be segmented, a respectively segmentation, two-section, three segmentations, four segmentations and five segmentations, Connected between each segmentation using ramp;
(c)Arrangement hangs ore body roof layering gallery inside the stope of each segmentation, leads to as the scraper of ore removal in arteries and veins Road, arranges fragmented transport gallery outside the upper Pan Mai that two-section-five is segmented, and fragmented transport gallery is parallel with orebody trend;
(d)Arrange ore removal drop shaft in the upper disk of ore body, the top of ore removal drop shaft crosses and is connected with five segmentation ore removal, lower part and One stage casing ore removal crosses connected;
(e)The back production in whole panel is divided into Two step mining, a step back production stope arranged for interval, stope use from lower and Upper substoping, in a step after all mineral building back production, sand off, carries out two step stope minings;
(f)Back production one is segmented first, is crossed interior arranged along orebody trend from ore removal before this and is hung ore body roof layering gallery, so Play cutting upwards close to studding in extension ore body roof layering gallery afterwards to go up a hill, the scope of freedom and compensation space as stope explosion, Stope explosion falls ore deposit using shallow bore hole, and scraper is crossed into stope from ramp, ore removal, shovels after dress ore and crosses fortune by ore removal Go out, load mine car in stage haulage way, and so on, until a substoping finishes, cementing one point using cement tailings Section dead zone, crosses interior arrangement filling counterfort in ore removal after sand off, prevents obturation from flowing out;
(g)After one substoping, filling, go to two slicings, personnel and equipment and enter two points by ramp Layer, two it is layered and parallel arrange a fragmented transport gallery in orebody trend, fragmented transport gallery is connected with each ore drawing in stope crosscut, It is identical with a segmentation that two-section adopts cutting process;
(h)Scraper is crossed into stope from from ramp, ore removal, and shovel is crossed after filling ore by ore removal, fragmented transport Gallery transports, and pours into the drop shaft that ore removal crosses the end, and so on, until two-section back production finishes, it is cementing using cement tailings Two-section dead zone, crosses interior arrangement filling counterfort in ore removal after sand off, prevents obturation from flowing out;
(i)Three segmentations, four segmentations, the process for stoping of five segmentations are identical with two-section.
Preferably, extent length 100-150m, level interval 50m;Height of lift is 10m, orebody thickness 4-15m; Width of stope 18m, studding width 2m, point column is 4 × 4m.
Compared with prior art, the beneficial effects of the invention are as follows:
The present invention is adapted to the mining methods of thick low-angle dip breaking surrounding rock ore body in exploitation, and nugget is divided into several first Stall, is further subdivided into several stopes in panel, and the back production in whole panel is completed suddenly in two steps, and first step back production is adopted Field interval arranges that stope both sides, which are stayed, sets studding;A segmentation is divided in stope per 10m, after treating down each and every one substoping, is used After cement tailing cemented filling, the last segmentation of back production;Quasi- work arrangement disk on ore body is adopted in panel, to protect mineral building back production Security, stayed among stope set up an office column support goaf;Ore deposit, scraper ore removal are fallen using shallow bore hole;Treat that a step mineral building returns After the completion of adopting filling, two step stope of back production, the method for two step stope of back production is identical with a step back production stope.The present invention is suitable Run jointly and adopt middle thick low-angle dip breaking ore body, have the characteristics that back production safety, ore dilution are low.
