Description
Technical field
It is specifically a kind of to exploit breaking type thickness mine using coal mine tunneling machine the present invention relates to a kind of metal mine mining methods
The method of body.
Background technique
The domestic metal mine exploitation overwhelming majority falls miner's skill using conventional blast, and the construction technology is simple, cost savings,
It is very high to fall mine efficiency, mechanization and large-scale production easy to accomplish.But for breaking type metal mine, traditional is quick-fried
Miner's skill of declining then exposes many drawbacks, and since ore body is broken, the exposed area of permission is small, exposure duration is short, therefore, one
As in the case of, these mines have that mining efficiency is low, and operating personnel's quantity is more to some extent, and support pattern is single and safe
Property is poor.Especially breaking type thickness ore body is difficult to realize safety and high efficiency since the easy bulk of ore is caving after blast disturbance.
Coal mine tunneling machine is called boom-type roadheader or stone head development machine, because the country is applied at first in Coal Mines lane
Road tunnels and obtains this name.Suitable for tunneling break up coal rock hardness degree f=4 ~ 8, other roadway constructions, section configuration can be used for
It is any to adjust.In general, cutting head of roadheader power resists in 40 ~ 400 kW, main screw lift in 10 ~ 160 t, cutting rock
Compressive Strength reaches as high as 170 MPa.Since development machine has the characteristics that driving speed is fast, high-quality, safe and efficient, big
The application on medium size coal mine mountain is very universal.
As attention degree of the state and society to mine safety is higher and higher, the metal mine of ore body breaking type is come
It says, traditional miner's skill that falls needs to improve.Since the developmental joint fissure of breaking type ore body is easy into after ore is disturbed
Block falls off, and therefore, is acted on using the lasting rotation of coal mine tunneling machine cutterhead and drilling, sufficiently splitting between expansion breaking ores
Gap can preferably control ore peeling rate, to complete machine breaking.Simultaneously as the disturbance model of tunneling machine cutting ore
To enclose very small, the overall stability in goaf is preferable, as long as using reasonable mining technology, immediate support exposure ore-rock, filling
Goaf, so that it may so that breaking type thickness ore body realizes safety and high efficiency.
Summary of the invention
The technical problem to be solved by the present invention is to be directed to the deficiency of existing mining technology, a kind of safe and efficient land productivity is provided
With the method for coal mine tunneling machine exploitation breaking type thickness ore body.
In order to solve the above technical problems, the technical solution adopted by the present invention is that: a kind of exploited using coal mine tunneling machine is crushed
The method of type thickness ore body comprising the following steps:
(1) the level haulage gallery outside orebody trend arrangement arteries and veins, arranges a plurality of crosscut, crosscut perpendicular to orebody trend
Interior arrangement ore chute, people's row ventilating system and filling drop shaft, ore body end arrangement " Z " font turn layer equipment connecting taxiway；
(2) coal mine tunneling machine back production is utilized, carries out route type back production by direction along the pulse, one by one successively back production or interval back production；
(3) scraper follows coal mine tunneling machine loading for ore, is then transported to ore chute；
(4) barren rock consolidated fill is carried out to excavation using scraper, realization is adopted when filling, and reaches Mining-filling balance.
In the above method, it is on the country rock of ore body end according to ore body middle section height that " Z " font, which turns layer equipment connecting taxiway,
The multilayer segmentation that degree divides, and every layer of step-by-step arrangement slice drift are connected with the equipment that the gradient is 15 ° inclined gallery of going up a hill between slice drift
Lead to and is formed.
In the above method, the spacing of the crosscut is 50 m.
In the above method, the ore body is typical breaking type gold mine thickness ore body, 15 m of ore body average thickness, strike length
For 200m, single extracting drift specification is height × wide=m of 3.0 m × 3.0.
When the above method is used for gold mine thickness ore body, specifically include:
(1) the level haulage gallery outside orebody trend arrangement arteries and veins arranges a crosscut, arrangement in crosscut every 50 m
Ore chute, people's row ventilating system and filling drop shaft, ore body one end outer " Z " font of arrangement arteries and veins turns layer equipment connecting taxiway, for setting
It is standby to turn layer and cable passage, also serve as pedestrian and vent passages；
(2) coal mine tunneling machine enters stope from arteries and veins external equipment connecting taxiway, and first back production chassis is continuously tunneled along the pulse, using route type,
Single extracting drift specification is height × wide=m of 3.0 m × 3.0, and scraper is caught in the scratch board conveyor tail portion of coal mine tunneling machine
Ore, is then transported to ore chute, coal mine tunneling machine along orebody trend primary excavation complete strips along the pulse after, return to arteries and veins peripheral hardware
At standby connecting taxiway, successively back production or interval recovery mode carry out next back production along the pulse one by one for selection；
(3) in coal mine tunneling machine exploitation process, barren rock and cementing material are poured into the sublevel fill stoping drop shaft of upper layer, fill drop shaft
Arranged beneath quarrel, scraper utilize the push of scraper, extrusion capability from quarrel place scraper barren rock cementing material to goaf
Realize filling, artificial uniformly water spray to barren rock cementing material realizes consolidated fill, and wherein scraper packed height is up to 2.5 m-
2.8 m, residual altitude are carried out connecing top by artificial packed barren rock and cementing material.
In the above method, when the coal mine tunneling machine carries out one by one successively back production, 10 need to be greater than to scraper melt flow length
M after barren rock cementing material reaches initial set, just carries out next back production along the pulse, realizes that Bian Caibian fills, continuous stoping.
In the above method, when the coal mine tunneling machine carries out interval back production, without waiting, stope is adopted, is filled mutually there are studding
It does not influence.
In the above method, in the coal mine tunneling machine exploitation process, supporting will follow up in time, and top and help containing mine
Supporting, the bolting with wire mesh helped using metal material without mine are carried out using non-metallic rock and high strength fibre net.
In the above method, after often having adopted the ore of one layer of segmentation along the pulse, coal mine tunneling machine retracts slice drift, carries out equipment
It goes up a hill after caving, coal mine tunneling machine immediately enters next layer of back production.
Compared with existing mining technology, the present invention has well solved breaking type thickness orebody mining problem, is dug using coal road
Mine and ore removal are fallen into machine and scraper cooperation, then is filled with scraper and hand fit, mining, ore removal, filling procedure are reached
Efficiently, it works continuously, operation number is reduced, and labor intensity reduces, and yield is promoted, and the safety is improved, and is brought apparent
Economic benefit.
Mechanization degree of the present invention is high, reasonably devises and adopts quasi- engineering, optimize back production and filling procedure, realizes and adopt
Mine, filling continuous operations, reduce operation number, reduce labor intensity, greatly increase production efficiency.
