The invention will be further described below in conjunction with accompanying drawing.
The specific embodiment
As shown in Figure 1, a kind of stone mining technology that this specific embodiment provides is mainly used in the exploitation of common stone materials such as marble, granite, comprises the steps:
Once punching: as shown in Figure 2, on the stone material ore body 2 in mine 1, stamp a round 4 according to the position of the waste material 3 of default presplitting, for follow-up division is got ready.Presplitting is waste expects 3 as shown in Figure 2, and its length is C, and width is K, highly is G; In general, depth-width ratio G/K should split otherwise be difficult for dividing greater than 2, and is also inconvenient follow-up with its overturning.Spacing between the hole 4 generally should be between 10 to 100 centimetres, and preferred pitch of holes scope is 10 to 50 centimetres.
Once division: as shown in Figure 2, the hole of accomplishing fluently before utilizing 4 becomes large-sized waste material 5 with the part (the waste material 3 of presplitting) of stone material ore body 2 from stone material ore body 2 division open forms.Division can be used quick-fried rope controlled blasting, perhaps expansive agent for cement slurry static blasting, but preferred spalling device comes spalling, and relevant spalling device and method please refer to a kind of rock introduced among the Chinese invention patent ZL200710076924.X or concrete cracking method and device and comes spalling.
There is unsafe factor in quick-fried rope controlled blasting, and explosive force is bigger to stone material destruction, makes that the volume recovery of stone material is very low, has wasted valuable non-renewable resources, has also caused environment pollution, thereby slowly has been eliminated now.Though expansive agent for cement slurry spalling method is safer, need to consume more expansive agent for cement slurry, thereby cost is higher, has compressed limited profit margin, make that a lot of ore deposits are main and be unwilling to use.And expansive agent for cement slurry is very responsive to infusion time and temperature, and early stage is seldom consistent with the expansion rate of expansive agent for cement slurry in hole 4 of later stage perfusion.In addition, expansive agent for cement slurry is influenced by environmental temperature, is lower than 5 degrees centigrade and just can't have used basically; Chemical time is long, needs five or six hours at normal temperatures, is unfavorable for continuous, sharp work.At last, expansive agent for cement slurry pollutes the environment, and is not inconsistent with current environmental protection concept, thereby will be eliminated.
Relevant employing spalling device and spalling method realize the details of division, please refer to Chinese invention patent ZL200710076924.X, and this paper no longer describes in detail.
Need to prove, split the law is that the position, aperture from default hole 4 tears apart rock, and the spalling rule is the even application of force on the whole length in hole 4, the rock spalling is opened, both effects are more or less the same in fact, and when just adopting split the law, too dark hole is nonsensical, and the spalling rule can be applied to darker hole 4, can also adopt the series connection of more piece spalling device in case of necessity.
Back down: as shown in Figure 3, the famine material 5 that separates with stone material ore body 2 is backed down, make its overturning, convenient follow-up secondary split also avoids influencing the exploitation of follow-up waste material.This step can adopt hydraulic pressure apex stone device.Hydraulic pressure apex stone machine is a kind of novel mine special-purpose machinery according to the characteristics design of stone mining, is mainly used in mobile, the overturning operation of oversize rock material, has simplified original operating type greatly, and this part belongs to prior art, and this paper no longer describes in detail.
Secondary punching: as shown in Figure 3, on the famine material 5 under the exploitation, punch 6, for follow-up secondary split is got ready according to predeterminated position.This be because the famine material 5 that separates from stone material ore body 2 has tens cubes, more than 100 cube, even hundreds of cube be inconvenient to transport and following process, so is needed secondary split.The secondary punching is the same with the method and the mode of once punching employing, and this place is no longer described in detail.
Secondary split: as shown in Figure 4, do not have the partial segmentation of defectives such as crackle to open on the famine material 5 with bulk, formation can be transported the directly oversize rock material 7 of processing of back, and described oversize rock material can further be processed into sheet material or other finished product or semiproduct.The remaining part that defectives such as crackle are arranged is a waste material 8, can carry out the processing of subsequent step.
Splitting method and mode can adopt the spalling device and method that adopts when once dividing, and this place is no longer described in detail.But secondary split can also adopt the hydraulic pressure splitting machine.Splitting machine is to be energy source with the hydraulic oil, drive the piston rod assembly motion that is connected with piston by piston, and use the wedge amplification principle dexterously, promote two split blocks and do the action of splitting, its splitting power can reach the hundreds of ton, even go up kiloton, can be in tens seconds on kiloton megalith easily splitting open.Since splitting machine have volume little, in light weight, easy to operate, safe and reliable, use flexibly, friction when high efficiency, work, no impact, noiselessness, no dust, cleavage direction controllability, characteristics such as economical and practical, be extensive use of in extraction industry such as quarrying, mineral products and infrastructure at present, a kind of machinery especially is absolutely necessary in urban construction, river course mediation, disaster relief and rescue, work such as remove obstacles.Certainly, this step can also be adopted modes such as blade saw, string bead saw, rope saw, and with the waste material of bulk further separately, but this class methods efficient is low, energy consumption is high, cost is high, therefore advises that preferred splitting machine comes splitting.
Cut: waste material 8 remaining behind the secondary split is cut the stone material product or the semiproduct that become than small-sized.Behind the secondary split, flawless major part has become bigger building stones 7 in the waste material of bulk, but also has some to exist the part of flaws such as crackle and less stone not to be utilized, and this paper is referred to as waste material 8.The stone machine is cut in the employing of this step, and remaining waste material 8 and less stone behind the secondary split are cut into the stone brick, and the stone brick may also have several different specifications, a little bit smaller more also can cut stone or the stone matter mosaic that becomes littler.Cut Shi Jiye and belong to prior art, this paper no longer describes in detail.
Broken: as will to cut rubble and/or stone flour that the remaining stone in back is broken into all size.Through after cutting, the major part of waste material has all obtained effective utilization, but some littler stone is not utilized, and may cause waste and contaminated environment.This step is used crushing engine, and the stone of remaining smaller szie is carried out fragmentation, can sieve into the rubble of different size after the fragmentation, is used for different purposes.
A kind of stone mining technology that adopts the specific embodiment of the invention to provide not only can improve the lumber recovery of high-quality stone material greatly, promotes the profit of stone mining enterprise; And key is to make full use of this non-renewable resource of stone material, the approaching a hundred per cent of effective rate of utilization.
Above content be in conjunction with concrete preferred implementation to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
